Where Can I Find A Skin Simulation Tutorial? Jan. 22, 2020, 3:09 a.m.

Moin, unknown user,

with so many ways of simulating things (not only) in Houdini, your question is quite vague. You can start your journey by reading white papers about “soft body simulations”, study documentation on various “physics simulation” out there, read some medical papers on skin … or you can watch some of the large number of Houdini tutorials. In order to really help you, it might be a good idea to show what you are doing, how far you have gotten on your own and where you are struggling.

Based on what you are describing, my suggestion is to split your simulation into two steps: Either simulate one layer (skin first, clothes second) after another. Or, different approach (depending o your actual setup), only simulate those parts of the skin that are not covered by cloth and use the skin “under cloth” as mere static/animated collision geometry for the cloth simulation.

It really depends on what you are after and whether you are doing isolated shots for cinematic reason or want to bake geometry for game-exports etc.

COP Substance - plugin for Houdini Jan. 16, 2020, 4:10 a.m.

Hi, Oleg,

just pointing it out here, don't shoot the messenger :-D

Honestly, I'd be careful with companies like Adobe. I would not expect their lawyers to accept an argument like “my product is called Cop substance” … actually, I would ask them and, if so required, change the name of my product, just to avoid an unnecessary quarrel on a battlefield that I neither could win nor profit from.
They'd probably not ask but sue you right away … so I would definitely take the action and ask them.

That said: License bought - and I will try to find the time to look into it, too! :-)

Hi,

just stumbled over this - fantastic work, I love it! The price - if I see it right - is extremely low and absolutely fair. I am going to buy a license right now, even though I have no personal use for it because efforts like this NEED to be supported.

That said, I would strongly recommend to not call it “Substance” in any way. I haven't researched whether Adobe (now owner of that stuff) owns rights to the name, but the original authors most probably do. Besides, they do own patents (which, as far as I have followed discussions about what they got patented, I found funny, as the same kind of things have been done since the beginning of coloured computer graphics )
It would be quite sad if you had to shut down because of name-infringing or even patent-issues.
