hey guys

how can i animate particles or objects along the blue surface (surface is deformed by bones). i need to visualize airflow inside a device.
i could do it with a prerendered image sequence mapped on the surface, maybe there is a better way. could this be done with flocking?

thanks for help,
Andy

Could you not create a curve, skin that to the bones also and use as a motion path for the objects, curve constraint or similar?

If you're willing to place control items again, try particles with the path wind. This takes a sequence of nulls to control the flow of the particles.

Cheers,

You could animate a procedural texture along the object with our without UVs.
You could also use the same bones to animate a particle object that morphs along the bone chain which could be pretty simple considering you already have the bones in place.
After that you could use actual particles as the others have suggested.

i used wind path in some other projects with mixed feelings ;-) loosing particles in sharp curves and stuff.
morph along bone did work but the particles distributed on the undeformed surface instead of the bone deformed surface...

at the end i used the deformed surface and animated a turbulence texture on the uv. for the UV offset i animated a null on the Y and used that in node editor. is there no time node?

thanks for your inputs,
Andy

You can animate UVs in the texture layers panel or by using nodes.

Apply 'morph along bone' to a line of points, and apply HVs to the points, instead of messing with emitters.

Cool trick Mr Rid! :thumbsup:

DP's spline deformer is probably easiest, instead of morf-thru-bones.

yes, was kinda wondering why it wasn't mentioned...
