such a big limitation - or am I mad?

I'm trying to simulate a projector map - you know, light shining through a net curtain for example, casting a shadow onto an object.

I'm pretty sure octane has no support for projector lights, so I created an object with an opacity map (lace) and put that in front of the light - the light does not shine through the object, the lace curtain completely blocks out all light. I've tried switching to path tracing but that does not work either.

So, am I going mad? Or is this not possible with octane? I'm working on VFX for a short film and maybe I'll have to use another renderer.

be sure to turn on "alphashadow" in PMC kernel

made a short test. diffuse material with mosaic opacity texture.

cheers

edit: works also with direct light and path tracing

here a single sided specular material, index=1.0, map in transmission port and fake shadows on (option in specular material).

Hey Boris

Thanks for this!!! Always wondered what that checkbox was for, just didn't think....I'll jump back on tomorrow and test.
