I started using spidtree to create a trees for our 3d scene and ran into a problem.
After export into obj I import trees into 3ds max and divide polygons into independent meshes based on material ids, that will be a different surfaces with its material in one mesh in unigine. After import in unigine and set materials I have 2 problems: billboards dont work in meshleaf materials, foliage remains static. When I enable foliage animation in material editor, foliage detached from tree and fly near it. I try to use materials from demos with trees, result don't change.
