VRayBitmap and named tags

[Mnietek2707]

Is this supported in Vray GPU? I try to use user-defined properties in filename.
I can't get this to work...
In CPU mode - no problem...
V-Ray 5, max 2020

Do you mean the <frameNum> tag? There is an issue with this tag in V-Ray GPU (internal bug-tracker id: VMAX-10451). I'll bump its priority additionally.

I mean User-Defined Properties. From help https://docs.chaosgroup.com/display/VMAX/VRayBitmap:
"You can specify node user properties between the < and > brackets. At render time, V-Ray takes the tag name and looks it up in the node's User Defined properties for the shaded object to determine the value of the tag."

Pardon. From what I tested, it actually works the other way around (works on GPU, not on CPU). What the specific V-Ray version build you're using? Could you attach a simple scene here?

Simple scene: User Defined tags.zip
V-Ray 5, hotfix 2 (5.00.05 build 00001)
Below renders from CPU and GPU respectively.
Interesting is that during light cache calculation images are visible and then later on disappear...

You're right, there seems to be an issue with tag values as numbers on GPU. I've logged it (internal bug-tracker id: VMAX-10551) for developer analysis. As a workaround, try setting your object user-properties to "awers=srodek1" (rather than "awers=1") and do the necessary correction in the VRayBitmap location name.
