V-Ray 5 Version 1.4 constant crashing

[dabel61]

Hi, I recently upgraded to V-Ray 5 Version 1.4.

I am finding that V1.4 is very unstable when rendering in the VFB in interactive mode and changing light settings on the fly.
My settings can be seen in the first attachment. The rendering Engine is set to CUDA with both CPU and GPU engines engaged.

I have a few lights in the model; some IES and some simple ones from the Asset Editor.
Playing around with the light object attribute settings causes crashes within minutes.

Is there anyway to roll back to version 1.3? I have a sense that it was more stable, but I am not sure, since I only added these lights to my model recently.
See lights in second attachment.

Thanks

Hi Doug,

We cannot seem to produce such issues when changing parameters in Interactive (see recording), would it be possible to forward us a sample project file so we can try to reproduce this in our environment? You can send it via our contact form, just make sure to mention this thread (or my name) in the email. Thanks!

Other than that, you can, of course, revert to update 1.3 and confirm whether the issue is gone - if you select Show all versions you will be able to download it from here https://download.chaosgroup.com/?lic...248&product=47
