Tutorials on realistic foliage dynamics June 25, 2017, 7:23 a.m.

Primarily interested in dynamics right now.
Extremely vast subject.

Ideal goal would be to render a single small potted plant that is affected by some type of external force. Turbulence? Velocity field? Fluid? Wind?

And at a more basic level, a single leaf.
How would you model it so that

1) It will have some bend or flexibility

2) Be simple enough to scale up in number

What solver would be best to use?
I've been going thru cloth sim tutorials, wire solver tutorials, etc

Not a whole lot of tutorials out there and the few I could find are quite old.
Any plant experts out there?

Randomly choose between mutliple source objects for copy To operation June 23, 2017, 9:15 p.m.

Not sure how to do this but I need to randomly choose between multiple source objects in a copyTo point SOP.

Imagine a Sphere with Scattered points on the surface.

Now using a copyTo SOp imagine having to copy not just 1 object to these points, but randomly choose between multiple.

ie For 3 objects instead of copying just a green colored grid, randomly choose either a red, green or blur grid for the copyTo points (on the sphere) operation.

Retopology with imported models in H16 June 23, 2017, 11:15 a.m.

H16 has a number of new and or improved SOPs for massaging your geometry.

Can anyone share their preferred workflow when it comes to importing geometry from other 3d apps?

What if the source is a lidar or laser scan? Does it make sense to convert to VDB then remesh?

Is it a good idea to ALWAYS use a PolyDoctor SOP?

What about the sequence or order of SOPs? Do you always add a normal and Subdivide last?

Any feedback appreciated!
