Hello!

I've looked at several tutorials for vellum muscle sim but I was wondering what's the easiest way to add the muscle sim solver vellum on my skin mesh (make the muscle affect skin).


Thanks!

Hi Alexandra,

I partly answered this question in your other post here https://www.sidefx.com/forum/topic/96576/?page=1#post-424734, [www.sidefx.com] but since you are asking about the easiest way I thought I'd just add the following information.

Firstly, you would not use the muscle solver vellum for your skin mesh if you have separate muscle geometry (the tutorial video linked by Edward in another one of your posts uses the skin as a franken muscle, which I believe is a different type of workflow to the more typical one you are trying to follow).

Instead, after your muscle sim you will want to follow it with a tissue sim, using a tissue solver vellum node. Again, the best example and explanation of this setup is here https://www.sidefx.com/contentlibrary/muscle-and-tissue/. [www.sidefx.com] If you are happy with the tissue sim as your skin surface, you can then point deform your rest skin with the tissue sim. This would be the easiest sim method.

However, if you want more detail in the skin in the form of skin sliding and wrinkling, then you would use your tissue sim to drive a skin sim using a skin solver vellum node, as outlined in the example file.

I hope this helps!

Kind regards,
Liesbeth
