Maya rendering error solutions


Plugin configuration errors

Phenomena:

  1. Arnold renderer is used by the local file and Vray is configured on the platform, causing the inconsistent platform configuration with the local use.
  2. The plugin used in the local file is not configured on the platform.
  3. The version of the plugin used in the local file doesn’t match the one configured on the platform.
  4. Rendering failure or incorrect rendering effects.

Method: check if the renderer used locally is consistent with the one configured on the platform or not, if not, make them consistent.

Black Arnold rendered images

Phenomenon:

The renderer is Arnold and the rendered image is black or with black grids.

Method:

Check whether any elements are lost in the scene, such as missing texture or missing the texture in ass or missing ass files. Try to export the log to see if there is any error or warning.

Frame coverage problem

Phenomenon:

The rendering job succeeded and also the frame job didn’t fail, but the sequence in the output only had the first frame or only one frame.

Method:

Check if “Renumber frames” is ticked in the scene, if yes, untick it and save the scene, then resubmit the job.

Problem of outputting multiple frames from renderer

Phenomenon:

The renderer is V-Ray renderer, the frame jobs have been rendered for a long time and one renderer outputs multiple frames which are not for the current frame job.

Method:

Check whether the Animation mode under Render Settings is Specific Frames or not. The animation mode of Specific Frames will cause the marks of start frame and end frame rendered by Maya cmd inactivated, and hence all the frames in the same node will be rendered. Switch to Standard mode.

Output path problems

Phenomenon:

CPU works normally during rendering, the output is 0 kb and the name also has special characters; or the CPU works normally during rendering and log has no obvious errors but the rendering fails.

Method:

Open the scene to check the output path; or the output is wrong as it can’t have any special characters and absolute paths.

Unable to switch layer for processing

Phenomenon:

error message as: Error: file: C:/Program Files/Autodesk/maya2015/scripts/others/mayaBatchRenderProcedure.mel line 539: Cannot switch from ‘defaultRenderLayer’ to ‘SEA’ because of an override to a missing node within a referenced scene. Reload the referenced scene if it’s unloaded, clean up the referenced scene or remove corresponding reference edits if the node has been deleted in the referenced scene.

Methods:

  1. Open your scene first to check whether the manual layer reports errors.
  2. Openthescene to run the following MEL command: "C:/Program Files/Autodesk/Maya2015/scripts/others/fixRenderLayerOutAdjustmentErrors.mel"; fixRenderLayerOutAdjustmentErrors;

  3. Check whether the window has error prompt, if not, save the scene for reanalysis.

  4. After running the above MEL command, if any error is reported and it still can’t be submitted, run the following script in the python window to find the references to the problem, start from the second step to operate, and save the corresponding file if no error is reported on the running result and then resubmit it.import maya.cmds as cmds render_layer= cmds.listConnections(“renderLayerManager.renderLayerId”) all_layer = cmds.ls(type =‘renderLayer’) print cmds.listConnections(“renderLayerManager.renderLayerId”) print cmds.ls(type =‘renderLayer’) for layer in all_layer: if layer in render_layer: print layer else: cmds.delete(layer) print cmds.listConnections(“renderLayerManager.renderLayerId”) print cmds.ls(type =‘renderLayer’)
  5. If the problem remains unsolved after the above steps, it’s suggested that you import all references in the scene to the scene, save it as another scene and resubmit the analysis job.
  6. If it’s 2016.5 2017 2018, then try setting the environment variables and restart the client: MAYA_ENABLE_LEGACY_RENDER_LAYERS=1.
