As said in the title, I have objects that do not project shade and I do not know why it happens.
Ideas of when this can happen. Is it an export problem? opacity textures or others? All my trees have this problem. A tree does not project a shadow (no trunk, no foliage and another tree where only the trunk casts the shade, but the foliage of the plant projects the shade perfectly, but not the tree ???
I add all the sub objects to the shadow generator with addShadowCaster().
Thank you for your lights
