Shadows for transparency and 2-sided materials.

Currently I can’t find a way to make 2 sided materials get a shadow from the back side

The way is rather simple

So I see that you’re referencing the two sided materials, and yes that is currently turned on in the verge settings for the material. After some fiddling around I found that my issue was actually a setting on my light, which I had deleted and re-instanced in 3ds Max.

But as for the cutout planes, I see what you have achieved in the pictures, but I’m not actually sure how you’ve done it. Can you elaborate a little?

I gave you a reference to the particular parameter: shadowSide

About the screenshots:
object.material.side = v3d.DoubleSide – in both cases double-sided
object.material.shadowSide = v3d.FrontSide – the first image
object.material.shadowSide = v3d.BackSide – the second image

The plane has a flipped square in the center.

If you want both sides casting shadows at the same time use
object.material.shadowSide = v3d.DoubleSide

Ahhh, okay. I couldn’t see the geometry there so I thought you had a single quad and you were trying to show me a cutout.
Do you have any idea about the cutout/transparency shadows?

I don’t know what exactly you want to get. More details. If you don’t want semi-transparent materials casting shadows then just disable shadows for them.

I’m trying to planes with cutout materials. So for example, this grass is a plane with a texture on it. I’m trying to get the shadow to be that of the grass, rather than that of the entire plane.
