Bake material is used to correctly display the following textures : CoronaAo, VrayDirt, CoronaMultiMap, VrayMultiSubtex and MultiTexture. As default we don’t bake material.
When Bake material is activated, we’ll bake material at four times the resolution of the object's lightmap. That will create large texture, which slows loading time and increase memory usage. Therefore, by default, we don’t bake material to have better performance.
To activate Bake material:
- Use “Validate” window to select all object with a texture that requires baking.
- Select objects that you wanna bake then check the “Bake material” checkbox. That’s complete.
