Stiffening options is good, especially after import. In v1, you could select vertices and 'rigidify' by neighborhood or extension. However I never understood if this was just replacing the 'extended stiffness' options from import dynamic params (also labeled neighborhood/extension) or what. Regardless, I still haven't found a way to make something VERY stiff while still letting it be affected by gravity (e.g., buttons, belt buckles).

Another problem I have is self-intersection. I usually have self-collision turned off to make the sim faster, but even when I turn it on, I still tend to get areas where the mesh overlaps itself a bit. Ways to prevent this would be cool. I'm sure I could figure it out if I played with stuff like detection distance, etc more.

Reset sim -- Is there a way to accomplish this? I know you can go into sim history and regenerate the entire scene, but re-importing everything seems like overkill when you just want to reset back to the beginning by removing the sim-created morphs.

Params! This one is huge. The pdf has technical explanations of everything. It would be cool to have 'practical explanations'. For example in dynamic params we have stretch, softness and node weight. I NEVER alter these from the default. The pdf shows some technical stuff, but that's it. What I'd like in the tutorial is real life stuff like - 'See how this dress goes flat like a bedsheet after sim? Want it to retain a bit more of its original shape (folds etc), simply change stretch/softness/weight to xyz.' I know I'm just making stuff up, but you get the point. Clothing going 'flat' is a real-life problem I have with VWD (dForce tends to maintain dress pleats, etc better by default), so showing how I can mess with params to solve a real-life problem would be HUGE (for this specific problem, maybe I need to mess with rigidity instead, not sure). So a common problem/solution approach would be ideal for me and I suspect many users. Here are some other common problems:

These are just a few ideas. I'm sure there are tons of others, but wanted to mention some in case you were looking. Tutorials take time and time is money, so I'm not expecting practical examples of every problem/scenario (that would likely be impossible anyway), but wanted to mention some just in case you needed a pool to pull from (and more importantly, to illustrate how explaining the params in a real-world problem-solution example format would be most helpful).

Overall, I love VWD and am looking forward to upgrading to v2 once I can afford it. Thanks for creating it!
