Vray 3.5 Beta - 10 sec. hang at "Merging light cache passes" when stopping a render

[Alex_M]

Vray hangs at "Merging light cache passes..." for ~10 sec. when stopping a 700x1000px region render on 4500x2530px image. This happens only if beforehand I've loaded a 4500 px render from history that contains lens effects and denoiser render element. When I run the region render I've disabled all render elements and lens effects so the hanging shouldn't be coming from Vray denoising anything or applying lens effects. If I render from a cleared VFB (no image is loaded from history) the render stops immediately as to be expected. Is this normal? I can send the scene along with the necessary vrimg file that I load and seems to cause the slowdown.

That's weird and sounds like a bug, can you send us the files for investigation?

[Alex_M]

I just passed along the scene and the vrimg file.

I forgot to add that there's a long wait not only when stopping the render at the Light Cache phase but also when stopping the actual rendering. I've removed all maps and materials as they didn't seem to affect the reproduction of the problem.

Where did you send the files to support@chaosgroup.com maybe?

Yes, that's the email. Should I send again or maybe to a different email? Please note that the link will expire in a week.
