Triplaner texture and frozen transforms

[francomanko]

Hi,

I dont know whats going on here, but im getting strange artifacts when using the triplaner texture and freezing the transforms on some geo. I've attached the scene and image. In the scene, if you freeze the objects in the group, the texture seems corrupt, as shown by the objects in the 'frozen_transforms' group in the maya scene.

This is with maya 2016 and vray 3.60.01 but it seems to happen on vray 3.5 release as well.

Any help is much appreciated.

Thank you for providing the scene file. We managed to reproduce the following issue and this was reported to pur system. I will update this topic as soon as we have any progress.

Hi, im getting the same issue but with Anisotropy reflections and geo thats been smoothed and transforms frozen. This is only when the rotation is frozen, translate and scale doesn't cause any issues. Im guessing its a normal's issue, but i cant seem to fix it.

This is maya 2018 using nightly build

thanks

Can you send us that scene to support@chaosgroup.com ?

hi, I've attached the scene in its project folder..you will probably have to repath hdr map. I think its something to do with smoothing and freezing transforms ( or something ive done wrong), in the scene there are 4 cylinders..first 2 are unsmoothed, the second has transforms frozen and seems fine, but with the third and fourth, theres a problem.

Thank you for the file.
I can't identify where exactly is the issue in this setup, so i prefer to log it in our bug system and someone from the dev team will look into it. When i have any information will post it here.

ok so the issue is with the nasty reflection on the far right cylinder in the image...this is a duplicate of the geo next to it, but the only difference is the transforms (rotation) have been frozen, which seems to cause the error. It also only seems to happen on the geo that has been smoothed, the first too (pre smoothed geo) seem fine...so guessing its a normal issue.

Yes, it's totally reproducible when I duplicated the 3rd cylinder and made its transformations frozen, however I will be able to give you more information on why this is happening when our developers update the case in our system. For now it's looks like a bug to me, but let's wait for a while.

ah i understand..thanks
