Is there any way to use a texture on a mesh light?
Put your texture where it says “Use texture”?
Oh how did I post in the 3dsmax forum, thats a new one
I mean to post in softimage 
Ahh, perhaps someone else can chip in and help. I have no experience with Softimage.
Unfortunately this is not possible.
It’s a property and there is no way to attach a texture to it.
