Set as new Default not working for Vray materials and maps

[Vizioen]

Not sure if it's a wish or bug, but as the title says, when trying to set default values (for instance bump on 100), 3ds Max doesn't remember these settings. I've tried with a couple of maps, but nothing sticks. Max's native materials and maps support this.

Latest official Vray and latest 3ds Max 2025.

Hm, the bump multiplier seems to be written in the DefaultParameters.ini, so the issue is that it's not read for some reason. Most of the parameters I tested do work, though. I'll write back with more info.

EDIT: Try saving the New Default bump map multiplier from the bottom (maps section). It seems to work as expected from there (the upper one is an alias and probably the issue affects aliases only).

Hi Aleksander, thanks that seems to work. I also tested other ones like flip green channel in the normalmap, at first it didn't stick, but now it does, so might have been a pebkac issue.

FYI: Logged the issue (internal bug-tracker id: VMAX-14571). If you find some other parameters that don't stick, do write again.
