Re: render tree mixer/texture limit

[Matt Lind]

To get around the node limit, did you ever consider the FXTree?

Each texture in the scene is represented by a clip in the FXTree's Clips 
menu with an input and output.  This allows you to apply image FX (paint, 
composite, layer, transform, crop, filter, ...) to each texture without 
increasing the size of the render tree.

Yeah its an odd project and honestly we tried Maya, C4D and Houdini and Soft 
was the best option! Basically have a bunch of growing textures UV mapped 
onto tracked geometry to simulate a spreading ink/paint looking thing. 
Simulations were too difficult to control, too much R&D and didn't allow us 
to tweak little parts of the effect or create seams, etc. Made a crap load 
of offset animated textures, brought them into the render tree, moved a 
bunch of texture supports around and done. Looks/works great…just hit a 
ceiling with the node limit. Oh well.

Hot damn that worked! Thanks!! Tried to set it to points initially but it
didn't do anything unless I cranked it super high, makes sense now.

Re: strands generated on points

[Steven Caron]

Wow, been a while for me but... Don't use Emit On Surface and instead bring
in the mesh, plug it into a get data (set to point position) then plug that
into an Add Point node. That's bare bones so you'll need to init some
variables for simulation... Ie. Mass, size, shape, etc

Re: strands generated on points

[Jens Lindgren]

This one is easy :)
First, in you Emit from Surface Compund set Select Rate Type to Total
number of Particles and set Emission Type to Point. Rate doesn't really
matter when you want to emit from mesh vertices.
Then the secret sauce... Go in to your Emit from Geometry compound, then go
in to Generate Points compound. In there, bring up the Generate Sample Set
node properties and set Rate Type to All Points.
Tada!

strands generated on points

[Kris Rivel]

Trying to make a long exposure effect of a stick of LEDs twirling around.
Have a nice animated grid of strands flying around and it looks great.
Problem is the particles generating the strands are just emitting on a grid
and stick to their emit location so they're not lined up nicely on the
emitter. They're just spread around randomly. Hoping I can keep this but
only generate one particle per point...but keep the "simulation" working so
I can turbulize it etc. and keep my generate strand trails which only seems
to work on simulated particles, not a simple "add point" on empty cloud
setup. Any ideas?
