Super slow rendering/baking with emissive material

[3Digit]

Hi there,

we have tried V-ray after it was released it works pretty well but using emissive light material makes the rendering super slow and noisy. We use quite a lot of emissive in our Unreal scenes and it's not something we'd like to give up.

Is there any way to make baking/rendering with emissive material faster?

Thanks
Istvan

Hi, Istvan

Thank you for bringing our attention to this. At the moment there aren't any settings for speeding the rendering of emisive/light materials. In future we will add a special Light material that will be optimized and boost up the speed of rendering and will act like the mesh light in V-Ray. Unfortunately the downside of it will be that you won't be able to use textures and that your mesh has to have only 1 material slot. If there are multiple materials in the mesh then the optimization will not have effect. At a later stage this will be improved as well. We will mention when this feature will be available in the Announcement section of the forum so make sure to check that.

Best regards,
Alexander

Has the problem be fixed with the new update?

Hi, Istvan

No, this speed optimization has not been yet implemented.
