IMSTK-Unity: Burning a texture mapped deformable

[dervishan]

I converted the surface mesh I had into a tetrahedral form using TetWild. The script provided a surface mesh output for the new form as well. I performed UV mapping on this output using Blender and added as child object and used as physics and collision geometry as in the tutorial. At this point, my object became a deformable one with texture mapping as in the screenshot below.

My settings at this point as follows:

However, when I added the Burnable script, the texture disappears. How can I solve this problem?

Hi dervishan,

Thanks for reporting the issue. There’s been a recent fix for this bug here: BUG: Fix UV mapping for deformable dynamic geometry (9c87dbfb) · Commits · iMSTK / iMSTK-Unity · GitLab

You can either update your imstk-unity version to this branch: Files · refactor-needle-interaction · iMSTK / iMSTK-Unity · GitLab

or just fix it locally for now by looking at the commit I provided. It’s a single line fix.

When I finish cutting the cloth, the edge UV looks wrong. What is the reason?

Update: I found a similar problem with Example-PBDThinTissueCut in imstk

Has been resolved, needs to deal with the UV partition in the SurfaceMeshCut.
Only Example-PBDThinTissueCut has been processed so far. Pending further testing
