Thread: follow gradient
Post: RE: follow gradient

You're not dampening the velocity at all right now, which is leading to the issues you're seeing. Put a Slow operator above your Surface Force with 100% strength, and increase the gradient ascent forc...

Thread: C# scripting, range（）
Post: RE: C# scripting, range（）

All C# syntax is valid - and the Math.Random library has range functions, or you can use tyFlow's exposed random range functions. Just initialize a generlic list of ints and fill with random values.

Thread: tyMesher bug (?)
Post: RE: tyMesher bug (?)

Hmm...I'm unable to reproduce the issue in the file you posted above. Does it occur immediately when you load that file w/tyFlow PRO? Or does a setting need to be tweaked to have the problem occur?

Post: RE: spin op "Relative to radius" missing?

Value operators should now be used for relativistic logic like that - although you're right, the legacy parameters are still in the docs in various places.

I can see that VRay is querying frame 0 at a certain point in the frame prep process - this causes tyFlow to update to frame 0. Nothing I can really do to prevent that from what I can tell. If you sen...

Thread: TyCache Performance
Post: RE: TyCache Performance

PointCache just updates the mesh vertex list. tyCache updates the entire mesh - the tradeoff is more flexibility at the cost of performance.
