surface wrinkles - super gnu - 04-06-2019
im going a bit potty trying to shrink wrap something. im finally getting somewhere andfter spending a whole day tweaking settings semi-randomly.
both cloth and collision object are pretty high res, and im up to 1/16 and 8 steps.. Every time i change one setting i have to rebalance all the others..
however, there is one effect which im not sure how to fix.
see attached screengrab. i get this bumpy, mottled effect over my collision objects.
im using "shape radius" for both my particle and collider radii, since it seems to give the most stable result. i was going mad trying to use "scale radius" to be honest im still not sure when i should use one or the other.
any suggestions? i wont be able to use this for my project, unless i can get a super smooth stable result. i can fix it to an extent with a relax after simming, but that kills too much detail if i turn it up high enough to fix the mottling.

check out the previous thread on shrink wrap .. that may help you

yeah that was my thread.. very helpful it was too, and im getting reasonably good results.. my issue is glitchy surfaces where collisions are happening. as per screengrab.
its basically due to not really understanding the whole collision radius concept, and knowing when to use each of the different modes.
ive done a few more iterations now, and ive found that "shape radius" for particle collisions and "scale radius" with a multiplier of 0.9 for geometry collisions seems to give a clean result.

When I set up those other files, I noticed that the radii really need a progressive scale adjustment for certain effects. I didn't get a chance to see if that is already built in there or not, but if not, it would be nice to have the option to link it to the bias value for some art-directed results.
