when using VRay or Arnold Materials, textures will only be imported if they are located in a folder named "tex" in the zip root directory special Cinema 4D objects (Text, Extrude) can only be hidden by setting their visibility to hidden for rendering (bottom red dot) and not by hiding their parent objects .c4d files larger than 1.5 GB might not process successfully objects with multiple selection tag, materials and UVs in certain constellations might not preserve uv mapping correctly when using multiple texture offset U and V and and Length U and V on multiple objects with same material, Aura™ only imports one. (workaround: create a individual material for each individual offset.)
