(Resolved) IPR Keeps on restarting (Vray 5)

[tobiasroesli]

Hi, I saw that there's a similar Post already.

I have the Problem that IPR keeps on restarting but the difference is that I use Vray 5 (vray_adv_50050_houdini18.5.40
I changed Graphic Cards today from 2x RTX 2080 Ti (NVLINK) to 2x RTX 3090 (no NVLINK). Since then it's doing it like that. worked normal before.

Nvidia Driver : 460.89-desktop-win10-64bit-international-nsd-whql

I'll send the dump file to support.

Cheers!

It's fixed with the newest nightly (vray_adv_50050_houdini18.5.408_b6775a0_11069)

Thank you for sharing, Tobias.

We seem to be still having this problem. IPR restarts X amount of random times before maybe randomly working.

Maybe this log can give some ideas

Same here with vray 4. Please fix this, it's almost impossible to work that way. We switched to 18.5 and had to update vray to make it work with the new houdini version. I can send a scene where it happens via mail if that helps.

This is still happening for me in h18.5.596 py3
Seems to trigger when I go into the /mat/ context to modify a vray mat builder material. Works after a houdini restart, until I go into the /mat/ net again

edit: it works for some models, might be related to instancing? I'll see if I have some time to create a repo
