i am wondering if casting shadows from a light on a geo with a phong MAT using an alpha textured shape is possible ?
Basically, i am using a rectangle SOP on which i apply a circle texture (black and white) to cut a hole inside it. Phong MAT is set with alpha ON. A filled rectangle is placed behind this layer as a background on which i try to cast a shadow from the hole.
Using a light on that geo works as expected but as soon as i turn shadows on, the hole turns black.
I don’t know how it works under the hood, but it seems like shadows are not possible through an alpha textured SOP right ?
Of course it is working if i import a 3D rectangle mesh with a hole inside.
See attached file : turn shadows on/off in the lightCOMP

Thanks a lot.
