VRayUserString doesn't animate

[mQvfx]

I believe this issue is being looked at by the support team, but please allow me to post it here in case there are people who have run into the same issue.

I have many cards (poly planes) with image sequence textures.
I'd like to be able to assign only 1-set of VRayLightMtl + file texture node to all the cards, with each card gets different frames from the sequence. I use VRayUserString_attrName to do it:
https://docs.chaosgroup.com/display/...userattributes

I use an expression to set VRayUserString attributes on each card with 4-padded frame numbers.
For example:
[at frame 1]
card_a = texture frame 0001
card_b = texture frame 0006
card_c = texture frame 0015
card_d = texture frame 0029

[at frame 2]
card_a = texture frame 0002
card_b = texture frame 0007
card_c = texture frame 0016
card_d = texture frame 0030

[at frame 11]
card_a = texture frame 0011
card_b = texture frame 0016
card_c = texture frame 0025
card_d = texture frame 0039

This works when rendered only one frame at a time, but it stops working when rendered in batch. It renders all frames the same as frame 1, which seems that VRayUserString is not working as it should.

I can provide a simple test scene data (about 8MB zipped).
Should I put a box.com download link?

I believe the forum supports up to 10MB zip archives so it would be better to attach the file here.

OK, I've attached a sample scene setup to this message.
Any help would be appreciated.

The combination of dynamic attribute and Expression does not work by batch?

He is waiting for the reply of ChaosGroup.

Thanks for uploading the scene. We are investigating the issue, as soon as we get any update from the developers we will let you know.

bump!　bump!

We have reproduced the problem and we are currently looking for a solution.

This should be fixed in the nightlies, as well as in the stable builds and the official update: http://forums.chaosgroup.com/showthr...-now-available
