FUR. HAIR. Deform Groom using Sim curves?!?

Recommended Posts

Hi, 

Anyone knows a good way to deform groom using sim curves? as guidegroom deform doesn`t seem to work for me and pointdeform has some other issues.

Do I really have to sim low res curves and then apply hairgen for full res?

Problem is that i have my groom done already and want to sim approx 10% of curves and only the long ones and deform my groom by those curves. Obviously I can`t acces Furtility, so is there any other good way using Houdini to do it?

Thanks

Here is the simple example of what I`m talking about:

That`s one way to do it.

pointdeform based on connected piece, but for each is heavy even on this basic scene. On my groom it would take ages...

Anyway I could do something like this without a use of for each loop??

Cheers

I guess I could speed up everything by using compile blocks. Just need to take out timeshift from foreachloop. Never used compile though.

Ok so Compile block made it wayyyy faster.

But I`m still curious what is the best way of deforming groom to sim curves. This can`t be it...

I mean it works, but still slow...

Has anyone done it in houdini???

you could speed it up a lot separating the capture step from the deforming step. You capture once, which takes lot of time and it would be always the same, and just deform on every frame.

I'm referring to point deform's capture and deform parameters.

Thanks Andrea.

I`ll give it a go!

I`m using the setup with compiled for each with point deform for this project. But there must be better way of doing it. Anyone? :)
