Contributor alexn007 Posted August 19, 2022 Contributor Report Share Posted August 19, 2022 (edited) Hoping someone can help me out here. I'm trying to get this to work, and I'm up against a bit of a time constraint. I've been trying to bake a ptex displacement map from my highpoly mesh object to my lowpoly mesh. But after the bake process the model doubles in scale, but this only seems to happen when baking to Ptex. Am I doing something wrong? Here's a video with my process. Thanks for any help with this! ptexBakeScale.mp4 Edited August 19, 2022 by alexn007 1 Quote Link to comment Share on other sites More sharing options...
Advanced Member Elemeno Posted August 19, 2022 Advanced Member Report Share Posted August 19, 2022 tried to replicate ... honestly cant , works fine ... might be due to symmetry? Quote Link to comment Share on other sites More sharing options...
Contributor alexn007 Posted August 20, 2022 Author Contributor Report Share Posted August 20, 2022 (edited) I've tried the symmetry sug, even on multiple computers, even unistalled and reinstalled. happens every time. what version are you on?

Contributor alexn007 Posted August 20, 2022 Author Contributor Report Share Posted August 20, 2022 I'm using .41. I'll try 39 Quote Link to comment Share on other sites More sharing options...
Contributor alexn007 Posted August 20, 2022 Author Contributor Report Share Posted August 20, 2022 I just tried in version .39 and still having the same results. It only happens when trying to bake in ptex, all the other bakes are good. Not sure what to do or if this is truly a bug. @Elemeno are you saying that you are now seeing this in version .41 or are you not seeing this at all? Thanks for looking at it, by the way. 1 Quote Link to comment Share on other sites More sharing options...
Contributor alexn007 Posted August 20, 2022 Author Contributor Report Share Posted August 20, 2022 @Elemeno My steps are to bring in a mesh either through the sculpt room option in the opening menu, or to import it through the import as vertex paint mesh. How did you bring in the high poly mesh? I'm wondering if that's what I'm doing wrong, although I would think it wouldn't matter how or where we bring in the source mesh. I'm working on a project where my high poly mesh is millions of polys, and I find if I bring it in through the paint room first, I run out of memory, but If I bring it in as a vertex paint object it's fine, except for the ptex baking scale issue I'm seeing here. I would like to try and replicate your steps and see if I get a better result. Would you be up for sharing your steps? Thanks again for any help. I'm really trying to do this in 3D Coat so I can share this process with my coworkers. Quote Link to comment Share on other sites More sharing options...
Contributor alexn007 Posted August 20, 2022 Author Contributor Report Share Posted August 20, 2022 (edited) @CarlosanI've Identified the problem. Not sure if it's a BUG or just a setting that needs to be fixed to make sure the scale in 3D Coat is the same across all rooms. If you import the same object in the paint or modeling room the scale will be different than if you import from the sculpt room or import via file>import>for Sculpt/vertex painting. The image below will show the difference, and this is exactly the difference I see after baking with Ptex. The large mesh is from the model room or Paint room import, the small mesh is from the sculpt room or vertex paint import.
