The attached images have a difference I was not expecting. The scene has an emitter plane in a black diffuse tube pointed at suzanne. The only difference between the two scenes is that one has a specular emitter and the other a diffuse emitter. Why does the diffuse emitter emit so much more light? Why is the specular emitter so much more focused? Shouldn't they be of the same brightness? Does a specular emitter only emit once in the direction of it's normals, while the diffuse emits equally through 180 degrees from the normal?
And secondly why does suzanne appear to have specular reflection when the specular emitter is used, or is that just the way the render is accumulating? The suzanne model uses a diffuse white material.

Re: 'emitters' and material type
That's a strange one - Ono is best suited to answer this.
Re: 'emitters' and material type
Could be a bug. Dmn, can you please simplifiy your scene, maybe so there's just one emitting triangle in a box?
Re: 'emitters' and material type
i don't have such issues. i tried with and without emission scale - same result
Check normals, dude!
Re: 'emitters' and material type
I was running blendigo 2.0.10. Updating to v2.2.1 fixed the problem. It seems there was a bug, or an incompatibility. Thanks for the responses.

therefore always write the version you usedmn wrote:I was running blendigo 2.0.10. Updating to v2.2.1 fixed the problem. It seems there was a bug, or an incompatibility. Thanks for the responses.

Re: 'emitters' and material type
Yeah sorry SmartDen. Or update to the latest version before posting about a problem. I should know that by now.
