No Decay lights for RT GPU

V-Ray V-Ray GPU Requests

Would it be possible to have no decay working in GPU for lights?
It’s massively used in archviz to flood light inside.

I noticed at the same time a bug :
If you create a light with no decay in production mode.
You switch to RT (straight in cuda), it will render black. If you untick no decay, it will render, and once you re-tick the no decay, it will render as if it wasn’t ticked.

Unfortunately the “No decay” property of the lights is not supported in RT GPU.

I noticed at the same time a bug :
If you create a light with no decay in production mode.

I can’t reproduce it in a simple test. Which V-Ray build/3DS Max version you are using ?

Hey,
Can’t reproduce it here either, one off I guess.

Hope the no decay will be implemented anytime soon as it’s quite critically used in interior archviz.

I think this used to work at some point, will check it out.

I run in the problem too that I miss the no decay option a lot. Please bring it back.
