Level Design Make Material not cast shadows
- Thread starter Murphy

Far as i am aware, a light casts a shadow. To a static mesh.
I didnt think materials cast shadows. Isnt it just a static mesh casting a shadow onto it?

Yes, but StaticMeshes have materials on them too. In my case I have a StaticMesh which contains glass, but the glass casts shadows as if it was solid.
Now, I could split my StaticMesh in two seperate models, one for the glass and without the glass, but if there was a possibility of making a material not cast a shadow (like a texture with a completely transparent alpha channel or the black parts of a masked texture) I could just apply that to my glass.
It's possible to turn off the collision per material, so I figured it might be possible to turn off that it can cast shadows.

What about a masked wirefence texture? Or not masked but with a completely translucent alpha channel? The translucent parts won't cast shadows. So the material definitely has something to do with it.

really ? mostly a shadowmap is used in combination with a wirefence or something like that. but maybe I`m completly wrong.

I don't know what a shadow map is, but you can do it via projector, which is the best way to do it because it's the most versatile and you can make it project on moving things (like players and their weapons) too, but if the resolution if the lightmap is high enough you can get pretty cool looking shadows on it too if you let light shine through a wire-fence.

depending on how many instances of this window you have it may be easier to split it into two different models, and on the glass part go into the properties and set cast shadows to false. you can still use the same texture for both models.

Does the frame really need to cast shadows? I would just set the whole mesh to not cast shadows. You can use a projector on the ground if you really want to have a nice looking shadow. Or just split the mesh into two parts as mentioned before.

It's not a framed window, it's something bigger that has window-planes in it. I'll split the model then.
