How to Make an Environment Scene in Speedtree

Natural vegetation is an indispensable element in games and scenes in the film and television animation industry! The production of some vegetation can almost add true feelings to the film. Fox Renderfarm, your TPN-Accredited cloud rendering service provider, share with you a tutorial about how to make an environment scene in Speedtree.

For the game masterpiece "Mysterious Sea", the scene production, from plants to objects, including objects, stickers and other details are close to the real, comparable to the general production of film and television movies.

There are also many scenes with vegetation in the film. For example, in the movie "Fantasy Forest", the large-scale vegetation scenes in the lens brought shocking visual effects to the audience, and almost all of them came from the realization of CG technology.

Compared to the realistic vegetation of "Fantasy Forest", the fantastic scenes of the movie "Avatar" many years ago have shocked everyone.

Then let's have a look at the technology behind the vegetation scene!

Tools used: Speedtree

At present, there are much vegetation making tools. Speedtree is definitely one of them. It has been used in many games, movies, CG animations.

The working principle of Speedtree is to generate branches through bones and generate trees through node connections. For example, the trunk is generated first, then small branches are generated on the trunk, and so on, and finally leaves are grown on the branches.

Its editing function of upstream is powerful and convenient. It can quickly adjust the length, thickness, bending, quantity, and random deformation of vegetations through parameters; it can create almost any type of vegetation in reality with a good model. At the same time, Speedtree also provides the animation function, which can generate the effect of natural wind and growth animation; the new version also adds the adjustment of the four seasons, which can control the process of leaves from green to yellow.

Speedtree is a really good tool for the environment artist!

How to Make an Environment Scene in Speedtree

Zhang Wei is an environmental artist and vegetation artist of a film and television animation company. He has participated in the production of many animation projects. He is good at researching and producing any kind of film-level and television-level special vegetation. Here, he will introduce the production of a single tree.

ZBrush High Model Creation

In ZBrush, the blockout of the trunk, roots, and ground is quickly made. After the shape of the tree is completed, the overall posture of the tree can be adjusted and details added. These details include bark, bumps, etc., all of which are completed with a basic brush.

The final thing vegetation needs are the shape of the tree. It is best to mix several different shapes together to make the shape of the tree more natural.

UVS and Textures

Use ZBrush's plug-in Decimation Master to reduce the surface of the model; export it to RizomUV VS; adjust the problematic points with Maya; split the UV and map in Mari; texture the stone and bottom and moss in Substance Painter. Then the production is completed.

Creates Assets in Speedtree

I use Speedtree to modify unique shapes. Leaves, vines, roots, grass, and other local shapes can also be made, including adding details to the tree, making realistic plant maps, etc.

At first, I only made the texture of the tree, but in order to make the tree and the ground better, I added some vines to the tree and planted some grass around the ground, and added some decorative stones around the stone and grass.

Maya Rendering

Then all the files are combined into a MAYA file. After the texture of the trunk and stones is built, the atmosphere of the scene can be adjusted while performing the light test.

After determining the final effect, it’s time to carry forward layered rendering. The last step is to put it into Photoshop to adjust the color and contrast.

Maya Tutorials: Game Props Modeling
Maya Tutorials: Game Props Modeling
Fox Renderfarm, a leading cloud rendering service provider in the CG industry, will share with you the game props model produced by Maya. In this Maya tutorial, we will introduce how to create a game-style 3D model based on conceptual design drawings, from ZBrush carving to high poly and low poly UV texture production. The following is a brief description of the process of making 3D models of games. I hope that you can have some understanding of the models used in games. Concept Before making a model, there are usually some conceptual drawings as reference for making. In this case, you can directly put the reference drawing in the production software Maya as a reference. Modeling Before importing into ZBrush for sculpting, you can first do some preparation work in Maya. If the model is relatively simple, such as stone, tree trunk, floor tiles, etc., they are relatively simple. You can use ZBrush to sculpt High Poly directly without making a Low Poly model. If the model is more complex, such as a biological model (animal or the like), you can make a Low Poly export OBJ file in Maya and sculpt it in ZBrush. ZBrush Import the low poly model into ZBrush for sculpting. From Blocking, make sure that the scale is appropriate. The most important thing is that the model does not deviate from the conceptual diagram. It is necessary to determine the overall ratio first, and then it is the part of some accessories, and finally the detail part. This process only uses the basic brush. Retopo The number of model faces sculpted by ZBrush is very high, which may be as high as hundreds of thousands of faces, or even millions. Such models cannot be used in-game engines. Therefore, the high poly model sculpted by ZBrush needs to be topologically a low poly before it can be used in the game engine. The topology process uses a topology software TopoGun, TopoGun can help the model Resurfacing and Maps baking, and the details of the model will not be lost. If you are making a single static map, then the model does not need to rig bones, it is not necessary to make low-poly and Normal map. UVS After the topology is completed, it is the job of the UV. Normal maps can be baked after the UV is split. The UV can be organized using some plug-ins included in Maya, or can be produced using other software. You just need to expand them and adjust as needed. Try to be as reasonable as possible. Schematic diagram of UV deployment and placement Normal map Before bringing the model to Substance Painter, you need to bake the details of high poly onto the developed UV to make the texture. Baking and texture can be made using Substance Painter or Toolbag, especially Substance Painter has many tools and functions, which is very suitable for realistic and cartoon-like texture production. These textures represent different information such as Normal map, Specula, Hight, and Gloss. The higher the accuracy of the texture, the better the final display effect of the model. Import the baked texture into the most commonly used Substance Painter software to create PBR textures. Some parts can be adjusted using some preset textures, and then output different textures according to different needs.

3ds Max Tutorials: Semi-realistic 3D Game Scene Interior Production Sharing(1)
Fox Renderfarm, as the best 3ds Max render farm in the CG industry, the tutorial we shared for you this time is from the 3D artist Thepoly, on how to use 3ds Max and Maya and other software to make a semi-realistic 3D game scene interior production process. This project uses the standard PBR process, using 3ds Max to complete the basic model building, and determine the object scale. Complete high poly carving in ZBrush, topology in Maya, baking in Marmoset Toolbag 3, Substance Painter to complete the production of PBR materials, and finally use Marmoset Toolbag 3 for rendering. Production process The production is divided into three parts: - Modeling - Material production - Rendering Modeling Before production, determine what materials, what objects are in the scene, and the overall ratio, and then determine the production order according to the ratio. Most of the scenes are walls and stones and wooden furniture, so they are the key part of the production. Quickly build up their approximate proportions in 3ds Max. Complete the medium polygon model After establishing the proportion of large objects, continue to build down the remaining objects in the scene. And further, enrich the details of the model. There are a lot of repetitive objects, just make a few different shapes. This does not seem to be too repetitive. Taking the above book as an example, many different types have been produced, which can reduce visual duplication. There are two fabrics in the scene, here is a pillow as an example, This product uses the cloth calculation that comes with 3ds Max. The specific process is as follows, Create blocking objects, Create a pillow basic model (the higher the number of segments, the better the simulation effect, but it also stuck). Squash and find the fabric in the modifier, Analog computing Finally, get a simple pillow model. (The folds of the fabric should be sorted out, the above is a simple demonstration. The curtains are the same, MD may have better results) Next, import the model into ZBrush for sculpting. Carving High Poly Take the wall and stone of the house as an example: After importing the medium-surface model into ZBrush, it is because of the irregular shape of the stone. You can use Dynamesh in geometry editing to edit the model. The No.1, No. 2, and No.3 brushes are used for large-scale carving of stones. The No. 4 brush adjusts the shape to prevent insertion. Finally, the No.5 and No.6 brushes flatten some edges and corners to make the structure hard. Thus reflecting the texture of the stone. The big idea of the wall is the same. Finally, use the noise in the surface, adjust the curve and noise ratio, etc. to simulate the graininess of the wall and the stone surface. Finally, add some details such as cracks and bumps to enrich the picture. Use the No. 6 brush mentioned above and press it again to achieve better results. (This part of the production reference is very important)

Behind The Scenes: Sagittarius(2)
Scene refinement Three main buildings were built according to the position in the original painting, and then the entire background was spliced out with these three buildings. This step is relatively simple. Then put the objects made at this stage into the main scene, adjust a few materials, such as metal, leather, SSS materials, give the corresponding model, add an HDR skylight, and test the entire scene. Biological refinement Now it's time to break the symmetry between the character's head and the monster's head model. This step needs to enrich the details on the skin, such as adding some wounds or something. At this time, you need to split the head UV. Use ZBrush to export the displacement map to view the effect in Maya. The ZBrush export displacement method is as shown above: first connect the displacement map exported by ZBrush in Maya. You need to open the subdivision level in the object properties. In this way, the object can restore the display effect in ZBrush. Lighting When the model with refined objects is put into the scene, you can start to adjust the lights. Decrease the intensity of HDR light and use it as a secondary light source, with a film light source as the main light source, and adjust the effect of the light and dark boundary line in the sun with parallel light. The effects at this stage are as follows. Use of character XYZ Here you can start to try the smallest level of detail processing on all objects, such as the XYZ replacement texture of the skin, the metal texture and damage traces of the equipment itself, and the skin after the XYZ replacement, as shown below: Equipment refinement The effect of making detailed equipment: UV The model is almost finished. Now it ’s time to split the UV. Here, UDIM is used to facilitate textures, a set of UDIM, a set of background, a set of skin, and then the cumbersome UV process. SP texture production After splitting the UV, the textures are created. All textures are made in the substance painter. A set of UDIM models are directly imported into the Substance Painter. As long as the options shown in the figure above are checked, they will be automatically recognized. When making textures, it is mainly due to color changes. The color changes should be rich but they cannot cover his original main color. Of course, the roughness changes are also very important. The following picture is the effect of Substance Painter. The skin needs to be color maps, roughness maps, and rough range maps in the Substance Painter. The color maps are obtained by mapping the real face skin (the same method as XYZ). The roughness can be converted using the previous XYZ three-channel conversion then overlay some random ALPHA textures. The rough range is to control the position of the highlight, and it is hand-drawn. Generally, the forehead, the tip of the nose, and the highlights on the cheeks are more obvious. Maya texture connection After the three pictures are drawn, you can add the rough range in Maya, and paste the roughness below: The color map is attached to the arrow in the figure below, and then radius gives a red color (light transmission effect). We also need to apply the XYZ displacement and ZBrush-derived displacement that we created earlier to the displacement channel, After the first pass of the texture, you can test the rendering, and then you need to adjust it according to the picture effect. Then the monster's head also needs to draw a map. Just like the human head, it needs three pictures of color, roughness and rough range. The next step is to replace the wings. The method of wings uses patch stitching. First, make a single feather map in three or four different positions, and then stitch it. What it looks like at this stage, Xgen hair production Let's start adding hair, XGEN for hair, each part should be separated into different Maya files when making hair, and then integrated into the main scene. Mainly how to import into the main scene, first clean the Maya file of the Xgen hair that is made separately, leaving only the growth bodies and the grown hair, and then directly import the cleaned Maya hair file in the main scene, and the imported file will be prefixed with a name. The prefix cannot be deleted, otherwise an error will occur. Rendering When rendering, you need to add AOV channel as a later auxiliary layer. The entire scene is divided into the foreground and the background for rendering separately, and the later scenes are stacked together to facilitate the final effect adjustment. Finally, the final picture is rendered, White mold, And the detail,
