UVW Tag Transfer Function Slow
-
I'm working on a possible effect, where I'm building on a CAD part, via the volume builder and mesher.
All fine!
However, the original CAD part is already carefully UVW mapped. I've found that the "Transfer" function works really well, transferring those original UV coordinates to the meshed object.
However...it's exceptionally slow / laggy. So much so, that I'm not sure I'd want to risk trying to render something like this.I can't exaclty post the actual project, being that it has client CAD at its core.
But in general, is it expected that transferring UV's from a simple shape, to a more complex meshed shape, will slow down?
(I kind of figure it should...)Thanks!

Hi entry-newspaper,
You give me nearly nothing to work with, no polygon counts, etc. Sorry.
A CAD file can represent a single piece or an entire machine. In contrast, Volume Meshing offers a wide range of density options. Even adjusting the Volume Mesher Adaptive setting to 0.5% can significantly alter the outcome.
So there is no answer for this one-time process in general. I checked the current version 2025.3.3, and it is fast. But I doubt it resembles your setup.Perhaps Remesh helps to optimize the result a little.
I'm not clear what you mean by rendering (still or animation?). Since this is a one-time process, the first image shows if it is OK or not.
If you feel that this setup is not as fast as comparable ones, please get in touch with tech support.

Hey, so sorry, Dr. Sassi. My original post is nearly worthlessly vague. I'll see whether I can find a minute to create a simpler proxy scene, so you can see precisely what I'm trying to accomplish.
But quickly, it's an animated effect, whereby I'm sort of turning the CAD part into a liquid-type shape, ultimately resolving in the shape of the original CAD piece. So the UV transfer has to deal with a frame-by-frame evolution of the volume / mesh builder.
More to come... -
Thanks for the reply, entry-newspaper.
I didn't want you to feel bad; it was more of an explanation for why I couldn't answer in a precise way. Sorry, it was received that way! I'm aware how my words can be received around the world in different ways. Yet, this happens. I should be more careful. Thank you for keeping going.
In the object manager>Object> Object Information. Tell me the number of the Volume object after it is made editable. That will help me to check.
Cheers
