heyhey, guys.
currently having a similar issue, just with self penetrating muscles. I found a post, where a user suggested to check the muscles in every solved frame, if they are self-penetrating.
I've written a check_per_frame script and found some problem areas, where self penetrating occurs regularly on specific frames, like the thin tips of the biceps.
Just wonder if it s even possible to make a self-penetration free full body muscle sim. I've cleaned the whole arm area, but it still happens. (by cleaning, i mean there is no more penetration between muscles or muscles with bones on the start frame)
my collision spacing is already on 0.004 and substeps 4. i ve also activated self-collision for the biceps.
the reason why i try to make a self-penetration free muscle sim, is because i ve got some difficulties siming the fat layer. The fascia seems to align well, but as soon as there are bigger movements, the skin would go through the fascia, where it gets stucked.
I thought the instability might come from the self-penetrating muscles.
do you guys have any suggestions for stabilizing my fat skin ? i mean, the muscle sim actually looks good besides of those tiny self-penetrations.
appreciate any help !
