3ds Max Scene File Specification

Render file requirements:

  1. All assets path must be within the E-Z disk drive, such as E:\project\files.

  2. File name and path name must be in English letters or numbers. Please avoid using special characters or Chinese (or other languages) letters as it might cause some issues in the later stage.

  3. Create a camera for a special plugin.

The impact of rendering due to the improper scene:

  1. Resulting in rendering time too long.

  2. Resulting in failed rendering.

  3. Resulting in incorrect render result.

Examples of failed rendering or incorrect render result causes:

  1. Scattered materials – no fixed folder is used and exists in many different disk drives or many folders are having a too long path.

  2. Material name or path has special 3.Reference object path is ABCD disk drive path or network path (which is unsupported on our platform).

The correct parameter setting set up:

  1. Or scattered assets, it is better to put all assets under the same project directory.

    pa4 1 Select the project folder you wish to use, then click “Make New Folder”. Please do not use ABCD disk drive path, network path or IP path.

    pa4 2 After a new folder is made, there will be some sub-folders which are automatically generated, please put the assets to the corresponding sub-folders.

    pa4 3

  2. Or asset or path that contains special character or symbol such as space, dot “.”, comma “,”, dash “-“ and other unidentified character or symbol, please rename the asset or path.

    pa4 3 1

  3. For any asset path that is using ABCD disk drive or network path, please change the relevant path to other disk drives such as E-Z disk drive path (especially for the reference files).

    pa4 4 Find the reference file or reference scene, open it and click “Merge” in order to merge the scenes. For larger reference file/scene, please change the path to the E-Z disk drive.

Mentalray FGM Rendering Error

Mentalray FG file not being uploaded will affect rendering:

Resulting in incorrect render result. b. Resulting in flickering sequence animation.

Mentalray FG file errorr cause:

FG map file is not uploaded (Desktop client is unable to retrieve Mentalray FG parameters information).

This can be solved by:

  1. Please use RayvisionSync transmission tool to upload .fgm file to our platform (Upload path has to be the same as the path in the scene).

    pa5 1

  2. If no .fgm file is used, please select “Off (Do not Cache Map to Disk)” under Final Gather Map.

    pa5 2

PNG Format Output Error

A pop-up window will appear on desktop client during render process, causing CPU to stuck and eventually leading to fail rendering.

Scene Loading IES File Error

  1. It might be due to the IES files inside have special symbols, such as "? |". Special symbol cannot exist within IES file.

  2. What is IES file:

    a. Introduction

    pa7 3
    p7 1
    IES standard file format, photometric data files in IES format can be created using the IES LM-63-1991 standard file format for photometric data. (IES stands for Lighting Engineering Association.) However, only the information related to 3ds max is described here. For a complete description of the IES standard file format, see the IES standard file format for electronic transmission of photometric data and related information developed by the IES Computer Board.

    The luminous intensity distribution (LID) of a light source is measured at a node of the optical network to obtain a set of fixed horizontal and vertical angles. The poles of the net are along the vertical axis and the lowest point corresponds to the vertical angle of 0 degrees. The horizontal axis corresponds to a horizontal angle of 0 degrees and the direction is parallel to the length of the light source. This type of optical network is generated by C-class goniometers and is most popular in North America; other types of goniometers supported by the IES standard file format are not discussed here.

    Photometric data is stored as an ASCII file. Each line in the file must be no more than 132 characters in length and must be terminated with a carriage return or line feed sequence. Longer lines can continue by inserting a carriage return or newline sequence. Each field in the file must begin with a new line and must be accurately displayed in the following sequence.

    IESNA91
    TEST Number of test report data
    MANUFAC Manufacturer of light sources
    TILT=NONE

    b.Features
    If the absolute metering method is used and the intensity values do not depend on the different lamp levels, the initial level lumen of the lamp is used in the test or -1. The multiplier for all the values in the file. This makes it easy to scale all the values of the Kendalla in the file when the device is measured in unusual units - for example, when the photometric values are obtained from a dialog box using a ruler on a goniometer chart. The multiplication factor is usually 1. The vertical angle in the optical network.

    Horizontal angle in the optical network.

    1 Unit type for measuring the size of the light-emitting opening. 1 for feet and 2 for meters.

    The width, length and height of the light emitting opening. At this point, Lightscape ignores these dimensions, since the specified luminous intensity distribution can be associated with any one of the light source geometry bodies supported by Lightscape. Normally it is specified as 0 0 0.1.0 1.0 0.0

    The vertical angle settings are listed in increasing order. If the distribution is fully listed in the bottom hemisphere, the first and last angles must be 0 ° and 90 °, respectively. If the distribution is fully listed in the top hemisphere, the first and last angles must be 90 ° and 180 °, respectively. Otherwise, they must be 0 ° and 180 °, respectively.

    The horizontal angle settings are listed in increasing order. The first angle must be 0 °. The last angle determines the degree of transverse symmetry that the intensity distribution shows. If 0 °, the distribution is symmetric about the axis. If it is 90, each region is symmetrically distributed. If it is 180, the distribution is symmetric about the vertical plane. If greater than 180 and less than or equal to 360, the distribution exhibits no transverse symmetry. All other values are invalid.

    The settings for the Candela value. First list all the kendra values corresponding to the first horizontal angle, starting at the value corresponding to the minimum vertical angle and moving the associated vertical plane upwards. Then the Kandler values corresponding to the vertical plane by the second horizontal angle are listed, and so on up to the last horizontal angle. Each vertical slice of the value must start at a new line. According to the instructions previously specified, open a longer line between the values on demand.

  3. Load error solution:

    a. Use Notepad to open IES file

    b. Delete the special symbol and save the file:

    pa7 2

    c. Open the 3ds Max file to reload a new file.

Scene Material Routing Problem

  1. There are 3 kinds of scene material routing problems:

    a. There are no corresponding materials in scene material file path, such as the scene file mapping path is F:\images\aaa.jpg, but images in local F set folder has aaa.jpg file (as shown in figure).

    p8 1
    b.Scene material files are not in the corresponding local place, such as scene file mapping path is M:\sucai\bbb.jpg, and after use it was put inside the F:\images folder, not in M set folder corresponding path.

    p8 2 c. One same material file in different positions, and using one same texture map in the two paths in the scene, such as there is a 111.jpa map, respectively on M:\sucai folder and F:\images folder, scene CCC.max, a teapot with the M:\sucai\111.jpg, a cylinder with the F:\images\111.jpg. In the process of uploading file analysis, 111.jpg is being uploaded to one path, but the other path without this texture map.

    p8 3

  2. Possible error may be caused by material routing/path problem:

    a. Wrong rendering result.
    b. Rendering failed, log map is missing or texture map cannot be uploaded to input.
    c. Preprocessing failure.

  3. Solution:

    a. Open the file and check if the scene material path is the same as local path:

    p8 4 b. If the paths are not consistent, press “Shift+T” to open the map info window, view the missing map information:

    p8 5
    c. Right click on the missing texture, select the “Set Path...”:

    p8 6 d. Click on the “Set Path… - Specify Asset Path”, then select map file path, then choose the needed map, click use path:

    p8 7 e. Verify the Specify Asset Path inside to show the path of the map, then click OK:

    p8 8 f. If different objects using one same texture map under two different paths, please change to one same path, this will also save analysing & file uploading time.

Scene Unsaved Information Solution

  1. Scene unsaved situation can lead to following problems:

    a. May lead to fail rendering b. Cause analysis process unable to obtain the related file parameters information.

  2. Solution (Set save scene information):

    a. On the menu bar, select “Customize – Preferences… – Files – Save File Properties”:

    pa9 1 pa9 2 b. Enable save file properties by checking "Save File Properties” and then submit the task to our platform for rendering.

Photon Model Errors and Solutions

  1. Problem:

    a. With the Animation (rendering) transfer to the Animation (prepass) for calculation of photons, resulting in rendering failure.

    b. With the From file transfer to Animation (prepass) for calculation of photons, resulting in rendering failure.

  2. Solution:

    When submitting the setting in our farm, please keep the same photon rendering mode with your local. (Under the condition of without modifying parameters)

    a. Use From file transfer to any of the below red boxes option for calculation of photons mode:

    pa10 1

    b. Use Animation (rendering) transfer to Animation (prepass) option for calculation of photons mode:

    pa10 2

Modeling Plugins Lead to Rendering Problems and Solutions

  1. Some modeling plugins do not collapse if the model is easy to go wrong, the proposed general use of collapse, for example, a few plugins, use the following modeling plugin, it is recommended to use polygon to deal with: Roofdesigner Quadchamfer Railclone Groundwiz Volumebreaker Scalpel Rayfire Floorgenerator

  2. Modeling plugins on rendering effects: a. May lead to wrong rendering result. b. May lead to 3ds Max software to crash during rendering.

  3. Modeling plugin example: a.1st type: roofdesigner

    The following is built in 3ds Max scene.

    pa11 1
    If this is the plugin model, please follow the following diagram for modification:

    Select the model, right-click the mouse, find Convert To: Convert To Editable Mesh, to edit polygons.

    pa11 2 Editable Mesh can be converted to editable polygons can be displayed.

    pa11 3 This is displayed as a polygon before submitting the render. b.2nd type: quadchamfer parametric modeling.

    The following is built in 3ds Max scene

    pa11 4 If this is the plugin model, please follow the following diagram for modification:

    Select the model, right-click the mouse, find Convert To: Convert To Editable Mesh, to edit polygons.

    pa11 5 Editable Mesh can be converted to editable polygons can be displayed.

    pa11 6 This is displayed as a polygon before submitting the render.

No Plugin is Figured Leads to Rendering Errors and Solutions

  1. For example: Using desktop client to submit test.max file, the following is the detail of test task: Software and plugin: 3D max 2011, VRay 3.30.05, FumeFX 3.5.4 Test project name: CEshi, only configure the 3ds Max 2011 without other plugins, resulting the render to fail.

    i. Re-drag the same scene file, then tick the ""Add config" in the pop-up window:

    pa12 3 ii. Tick the plugin that corresponds to your scene file:

    pa12 4
    pa12 5 iii. Click "Next" to next step.

Software and Plugin Loss Leads to Error and Solutions

  1. Supported Software a.Issue: The task is failed due to our platform does not have the software that corresponds to your render file. b.Solution: The user need to communicate with our customer service to confirm if we support the software that corresponds to your task in advance. If the software is right but task still failed, please check the project configuration software and make sure the version is correct.
  2. Supported Plugin a.Issue: If the user forgets to configure the plugin that corresponds to your scene in a project or the configured plugin has not been activated during the submission of a task, such as: If you are using RealFlow in your scene but our farm does not have the same version (exact version) of RealFlow which corresponds to your scene, although the task will successfully render the scene, the render result would be wrong. The following render results show correct and incorrect result: p13 1 p13 2 If you are using V-Ray as the renderer in your scene but our platform does not have the corresponding V-Ray version or does not configure the right version, then the task will be failed.
    b.Solution: The user need to configure the same exact version of plugin in the scene while the user is submitting a task.

TGA Output Format Compression Setting

  1. Issue frame0000_composed got stuck for a long time and showed "error" in a multi-tile/distributed rendering task. It is found that the file is still in the copy status, the finished file is 68GB. The render log showed that it is still in copy status.

    pa14 1 pa14 2

  2. Solution The user has to tick “Compress” option in V-Ray setting, or else the output file is big. Below are the reference figure for tick and untick “Compress” option:

    pa14 3 pa14 4

Blank Material Path Leads to Wrong Render Result and Solution

  1. Issue
    The corresponding map path is blank inside the max file explorer, generally caused by using the third plugin to import model or material, so the map path is blank which cause the program is unable to get the correct maps, then the render result has lost maps.

    p15 1
    Wrong Render Result:

    p15 2 Correct Render Result:

  1. Issue The Desktop Client app cannot recognize the file, fail to upload the file. Show map missing:

    pa16 1
    Show map correct:

    pa16 2

  2. Solution a. Using Asset Tracking (Shift+T) in 3ds Max to search the long path or special character file.

    pa16 4 b. Tick the file then tick "Browse". Find the map in the file browser window.

    pa16 5 c. Modify the map name and tick "Open" to open it.

    pa16 3

External Reference Problems and Solutions

  1. External reference file common problems: a. External reference file is not loaded. b. External reference file within the map file or the cache cannot be read & recognized.
  2. External reference problem affects: a. Render output is wrong, missing the reference part of the object. b. Render failure due to tiles or cache file is missing. c. Analysing/Pre-processing failure.
  3. Solutions: a. Please check whether the scene file loads the correct external reference, and external reference files need to be on the E-Z drive for absolute path.

    p17 1 b. Please merge the scene.

    p17 2 c. If the user is using the reference object, please merge into the main scene (as shown in figure), check all the three boxes in red frame.

    p17 3 d. Choose the reference documents what the user needs.

    p17 4 e. Choose what the user needs.

    p17 5 f. Click double-click the 3ds Max file, the user can see the loading objects that the user has chosen.
