For some reason VRay doesn’t call function “eval” of VRenderLight, but other ones (compileGeometry, init) are called.
Where am I wrong?
Perhaps V-Ray does not recognize it as a V-Ray light; did you implement the I_VRAYLIGHT interface for your ObjLightDesc object?

Yes, I did.
I found, if I call eval from Illuminate it works.
I am trying to optimize VRay Mesh Light.
Base Mesh Light
Modified Light
Nice improvement! 
yeah no kiddin. Looks better AND renders faster? Sign me up! 
What did you have to change to improve the meshlight?
Actually I wrote new light sourse type as modifier for geometry.
New comparison with GI IrMap + BF
211 VrayLights
1 modified geom object light with 211 polygons
incredible. I was always of the opinion that there had to be room for improvement with the vray meshlight/material, but this is pretty awesome.
Wow. Fantastic, research. Thats is a considerable difference.
Great Job!
A few requests:
* Can you post images with GI disabled?
* Can you do a very small animation (just a camera move)?
Thanks alot and keep up the good work.

What sort of optimization you use?
I’m guesssing some kd-tree/bvh and you search the lights close to the shade point first because they’ll have the greatest impact asuming the brightness of the light sources is the same?
I calculate light flux of source to decide how many sample I should use for this source.
Now I have gotten really clear and fast result.
That’s looking great, nice work!
Is this stable with an animated light source?
