Vray IPR blank materials issue
« on: January 31, 2023, 08:15:22 PM »
Hi,

We've been noticing for a while now then we using Vray IPR, from a certain moment, FP will not assign materials to certain objects. It seems like a memory/cache issue because at the beginning (first run) it will be fine. But later when changing objects and re-running IPR (or whilst running IPR) some object will just be white or black.

And it's not the objects, because hitting the vray refresh button will just make the issue move to another object, with the previous object now rendering fine. Today I've cycle through 5 rounds and then everything was rendering fine again.

It just seems to hit after a certain amount of time in a file, not because of a certain action. Any other reports of this issue, or a fix?

Thanks!

up to date MAX2021, latest vray/FP/RC, win10.

Hi,

First, let me mention, that the IPR / IR mode has several limitations (in V-Ray and in Corona as well) and it's hard and sometimes even impossible to fix issues that occur with the Interactive Rendering as 3ds Max wasn't primarily designed for it - a series of cheats are being used (from the renderer side and from our side) to make it work.

If possible, please feel free to send us your scene (ideally simplified and containing just this problematic object(s)) to helpdesk@itoosoft.com to check it here. In case of a big file size, please use a web-sharing service like WeTransfer. Ideally, if you'll be able to reproduce it on a minimal scene, which you can send us, it would be great. Thanks in advance.

Best regards,
