Sometimes UV Issue

[haniel1107]

Hello,
sometimes I have a problem with UV. Sometimes the order of material and UV is important. Not always, not on every scene.
But would like to know the reason, as I have a file with a lot of elements imported, where this behaviour is mixed...

Please take a look the screenshot. File with one object attached
Thanks..

Hi haniel1107 ,

I downloaded the scene, but could not get the same error you had.
Btw a good rule of thumb would be having a somewhat proper UV layout and staying away from the overlapping techniques, unless it's an asset meant for game engine and you want to save some resources.
Hope this helps

Hi Yunal,
thanks, for the tip, but this is an object out of a large turbosquid scene.
I am using last nightly build of vray5, win 10 S24.

BTW when you duplicate the object the error won't appear on the duplicated object... only if you move the uv tag on this object I've sent.

Thanks,
hani

Hello haniel1107,

Upon testing, I managed to reproduce the same issue. It looks like it happens when the UVW tag is placed after the material tag. If the order is changed, the issue is not reproducible.

I have now reported this to our developers (bug ID: VC4D-1119) and I will let you know once we have any updates on the matter. Thanks.

Happy you could reproduce it. Thank you!!

Hello deyan.hadzhiev or CG, do you know when this could be fixed. Or is there a trick or script I could use.

For example, I have a scene here with over 5thousand objects where the uvw tag is placed after the material. This happens when you import from maya ... I can not work on my clients request before I have brought all uvw in place...
As you can imagine, this is really bad... and costs me a job

Help or a fix is much appreciated and urgent..

And let me please add another request here... maybe you could consider to make a hotfix with it, as alone this bug is a hotfix worth, otherwise renderfarms like rebus will ignore this fix... ???
