How to train multiple clothes simultaneously

[xqyd]

Hi, Great jobs for your paper and code! I have one simple question: How to edit the smpl.json file so I can train the tshirt and the pants together?

Since these two obj files are located in the same folder, and multi-layered clothing simulation is a must for many applications, I want to know how to do it in your current code. Thanks!

Hi, thanks for your interest in my work!

To train multiple garments at once, the easiest solution is to merge them into a single mesh in an OBJ file. Note cloth-to-cloth interactions are not modeled in this approach, but it is possible to do it. To see how, you can look to a similar work of mine, PBNS (https://github.com/hbertiche/PBNS). Briefly, the idea is that collision loss is applied to garments iteratively, from inner-most to outer-most, with previous layers considered as part of the body (collider).
