Emissive material issues !

Hellblaster

Hello,

I'm here because I have a problem with my emissive material. I'm quite a newbie in UDK.

When i'm on unlit mode, the texture is fine, but as soon as i bake light, regions that shouldn't be glowing appears black. Maybe the problem come from my node ? I've tried with a new texture with only windows diffuse (on the screenshot) or with an alpha mask but i keep getting this problem. Maybe the amazingly skilled people here have an explaination ?

Thank you !

And forgive my poor english skill

Here are the screenshots. The first in unlit mode, the second in lit.

Does you object have a lightmap? If not, the engine will try to bake lighting into the object's vertices. The verts will probably bake black since they are so close (or in) to the wall.

Yes i have a proper lightmap for the windows, but in fact i have no light but my emissive texture, it came from this... Is there a way to light my diffuse whitout a light, like with the bounces of the GI ?

check the properties for your object and search for "use emissive for static lighting". should do the trick

Thanks for tips but i've already checked this, i've also played with the parameters, emissive boost.. but i keep getting this. I think i will put a small point light.

Thank you !
