Indigo Renderer Forum

Ok so, I've been working on a scene and slowly appending objects as I got into the "master file". And recently I created this new lamp mesh.

And whenever I add it in, it's the only one emitting light, and when I take it out, all the previous lamps work perfectly.

Ideas?

Something like this was discussed on this forum recently.

Can you elaborate:
- which exporter version
- lamp settings
- anything else relevant
- provide a sample .blend file ?

Oh yeah of course, sorry

Originally I was using Blendigo 2.4.8 with Indigo 2.4.7GPU beta but I upgrade both of these to 2.4.10 and the issue is still present.

All lamps are mesh lights: blackbody 3k degrees. the new one is actually a blend of scpecular with diffuse emitter (not sure if thats legal or not).

I'll send you the blend files by PM, it's my competition scene and I'm not done so I dont want to post it in thread yet.

I had the same problem when I my lamp was one object with two materials, one specular (perfect mirror) and one diffuse emitter. None, or only one, of the lamps would emit light. I think the problem is mixing specular and emitter because it went away as soon as I just changed the specular material to a phong with high IOR and exponent.
