UVW changes are not updated in RT

V-Ray V-Ray GPU Issues
1

In all my scenes I don’t notice any UVW updates in RT. Scaling, rotating using the unwrap uvw gives no realtime feedback.

Is there already a fix for this? Closing RT and re enabling all the time is not the point of RT me thinks :wink:

Which 3ds Max version are you using?

3dsmax 2008 x64

Unfortunately we are not able to support this for 3ds Max 2008; it works fine for 3ds Max 2009 and later though, because they have a new API specifically for tracking scene changes.

no problem Vlado, completely understandable

6

are there any other 2008 and below limitations for rt besides this?

7

We cannot capture some scene modifications, e.g. some modifiers, objects being created (you need to exit the create mode for the object to be detected); there are no other functional differences.

We are currently allays on max2008 64 for the pipeline production (“we don’t change a horse that win”, french expression, don’t know if it exist in english ;)), but we had already seen the limitation on max 2008 with VrayRT, so for some job, we are switching to max 2010, but it’s really a pain in the ass.
Does VrayRT work the same way on max 2009 ? (for all beside the fur?)
I haven’t done tests yet, but if it’s the case, we could switch on 2009 in place of 2010.

V-Ray RT works the same in 3ds Max 2009 and 2010.

Hello,

I am also experiencing this problem in max9…is there a fix possible?

Thanks

I found that hiding the object and then un-hiding it, updates the UVW mapping…not great, but loads better than restarting max…

Yep; moving the object will also work (or anything else that causes V-Ray RT to re-export the entire mesh again).
