Opacity maps to light materials?

[Will Gibbons]

I'm sure there's a perfectly logical reason as to why this isn't allowed, but I'm wondering what it is. I have a plane with a light material applied. I now wish to apply an opacity map to it so it appears to be a grid, not a solid plane. I'm assuming I need to model it and then import it.

Anyone else have faster workarounds or know why this is?

hmm - that reduce the solution to just emitted material type.
And in this case I found a funny effect. I used box map for the transparency texture and it creates the wrong rays. With proj to y everything is fine.

Excuse the German UI language - I guess you know my options.

Hmm. Yeah, interesting discovery, but not exactly what I was going after. Thanks for giving it a shot and sharing!
