Rendering material transmission over alphaMap

LR17 · February 7, 2023, 8:58am

Hello,
is it possible to render correctly (even with a hack, not a general solution) a material with transmission that is occluding another material which has alphaMap? In my use case I know for sure that the material with alphaMap will always be behind the one with transmission. I’m currently setting depthWrite = false to both materials and a lower renderOrder to the object that is behind, but the result is not correct.

Thanks!

According to https://github.com/mrdoob/three.js/issues/22009#issuecomment-864604563 seems that currently Three.js does not support displaying a material with alphaMap through a material with transmission.
