VrayRT background image resets buffer every update

[Moriah]

When working in RT mode, if i have a background image, every time there's an update it clears the buffer and restarts the render. If i turn the bg image off it works properly and doesn't clear it.

Plus its way slower to update with a bg image on.

Could this be fixed please?

Vray 3.20.03

Hi,

Would it be possible to post here or send a scene to support at chaosgroup.com that reproduces the issue ?
Thank you!

RT CPU or GPU ?

Can also confirm this.
I had a dome light + HDRI which was then instanced into env map slot. Every time i rotated the dome light it would stall and take ages to update.
If I cleared the environment map slot, it would then begin to update instantly.

Oh so that happens in the environment slot too? I was refering to the actual bg image on the buffer CC panel.

I can send a scene, but it's pretty basic, just add something to the env/bg image slot and compare speeds on and off. CPU and GPU btw

I would like to ask for a scene, because I can't replicate it here for some reason. Please post the file here or send it to support...
