Vray IPR rendering Proxy view

[JamesB]

Hello,

I think this issue has been present in the last two versions (I just updated to version 9.3.3 and the issue remains).

This issue is occuring when opening older scenes which proves this bug is new.
It also happens with newly created Forest Pack objects.

The issue is:
Vray IPR renders the FP objects according to the viewport display settings, not the render settings as it should.
If the viewport display is set to Mesh it will render correctly, when set to Proxy it will render a meshed version of the viewport proxy, and when set to Points-Cloud it will render nothing.
Production render mode works as it should.

Windows 10 Pro N 22H2
3DSMax 2026.2 (28.2.0.20659)
Vray 7.20.04.00000

Attached are the FP settings

Hi,

I'm sorry to hear that you're facing these troubles. I can confirm that we have already received reports of IPR-related issues also from other users, and we are currently analyzing it. It will need to be investigated more thoroughly by our main developers, and hopefully, a solution will be found soon.

Unfortunately, the IPR / IR mode has several limitations 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 and a series of cheats are being used (from the renderer side and from our side) to make it work.

Best regards,
