I was also thinking getting rig from Mannequin and using it in Blender with a new character mesh. One of the issues is that if the skeleton doesn’t match one from Mannequin, it won’t be accepted to Marketplace. I wouldn’t be able to make a new character from scratch and make it UE4 standardized.

Plus that only solves issue “conventionally animating Mannequin in Blender”. I could constrain it in Blender, but then it will be a total pain to get angles and limits correct. I guess Maya’s bone axes are different than Blenders? I’ll do some testing when I get time but you should be able to constrain the mannequin rig to your blender rig and drive it that way. Use this to add subtle color change effects without adding multiple tree models.We just had a long conversation in the hall about this and I guess there are some issues as to how the mannequin was built (specifically built for a Maya workflow). The SpeedTree Color Variation node (also pictured below) adds color variation to the material based on the models position/orientation. Use this property to control how quickly each plane disappears based on its viewing angle. LOD Type - Use this to control whether SpeedTree models smoothly transition between LOD states or pop between them like standard Static Meshes.īillboard Threshold - Billboards are modeled as a cluster of planes, each with a different billboard image applied. If vertex processing performance is an issue, this is a good way to reduce the vertex overhead on SpeedTree objects quickly. This value matches what you set in the Modeler on import. Wind Type - This property controls the complexity/quality of the wind shader applied to the material. Geometry Type - This setting controls what type of geometry is rendered and is set automatically. There are several options available on the SpeedTree node: With it connected, you will get SpeedTree wind and smooth LOD transitions.
If you disconnect it, everything rendered with that material will be identical to a Static Mesh. The SpeedTree node connected to "World Position Offest" (pictured below) is the only SpeedTree specific component. These materials get the basics in place but can be improved and tailored to suit your scenes.
#NOT YOU IMPORT 3D BLENDER MODELS INTO UE4 FREE#
It is important to note that you are completely free to edit the materials generated by the importer. The materials are of particular importance. Material assets for each component (draw call) of the model. Texture assets for each atlas, billboard atlas, and tiling texture map on your model. You can edit options on this asset like you would any other Static Mesh (e.g., LOD ranges, lightmap resolution, etc.). Once the import process is complete, you should have the following new assets (pictured below):Ī Static Mesh that represents your model. You can also add vertex processing to the materials, which puts a special SpeedTree node into the material that can handle wind, billboarding, and other effects computed per-vertex on the tree.įinally, you can import any collision primitives that were set up in the SpeedTree Modeler into collision information on the new SpeedTree mesh. In the import dialog, you can also choose to include detail, specular, and branch seam blending in the materials used on the 3D tree. Just importing the billboard mesh also creates a Static Mesh that can be used with UE4's foliage layers.
Or, if a tree will only be used far away and you want to save loading the 3D geometry, you can only import the billboard.
If a tree will only be used close-up, it is a "hero" tree, or you otherwise have trouble with the billboard as the lowest LOD (as is sometimes the case with dynamic shadows falling on the flat billboard geometry), you can choose to ignore the billboard mesh.
First is the choice between 3D geometry, billboards, or both. You have a number of options during import that are presented to you in the import dialog. You may want to make a folder for your model to keep the resulting assets organized as pictured below. The SpeedTree model will be imported into a normal Static Mesh object. This is the file you will import into the UE4 Editor. When you save a model in the UE4 version of the Modeler (or use the compiler for custom licensees), you should have a.
