Mesh Light Support

[philip_nel]

Rendering commercial interiors we often have organically shaped bulkheads that's lit up with led strips.
Typically we'll add a vray mesh light in 3dsmax in order to create enough sampling - just adding a vray light material doesn't give proper results.
Would be great if Vantage support mesh lights in future updates.

What is the issue with the light material? Can't get the proper brightness or it's too noisy? It's easiest for us to translate mesh lights to emissive materials in Vantage (we should have done it already).

VRayLight or VRayMtl self illumination
Their light emission intensity seems to be inconsistent with the brightness of the object. Can't produce very obvious lighting effect

Try increasing the value for "Max. sec. intensity" in the Advanced rollout of the Render tab or disable "Clamp sec. rays" entirely. Note that this might cause more noise and fireflies.

p.s. note that with the recently modified UI, you can input a large value in the text box beyond the current maximum that the slider allows.

I have tested that they are different. VRayLight will always get better results

Yes, this result is expected from very bright emissive materials like this one, when it is the main source of light. The plane is lit randomly through GI as the sphere does not count as a light source to get sampled directly, so there is a lower chance to hit the sphere from further away. You will get a similar difference in quality with V-Ray.

Yes, so I'm just explaining why we need VRayMesh support
