instance of instance?

Hi,

Kinda stuck here. Built like a little raspberry out of little spheres. Now i’m trying to do 4 other little raspberries, if it makes sense. I’m applying the same chop technique as in building the rasbperry but it doesn t work:(.

Hi there,

I’ts not possible to instance geometry within instanced geometry.
Instancing is happening on your GPU. Which means it clones & displaces the already created vertices of a mesh on the GPU. The clones stay on the GPU, so there is no way to know where the clones in 3d space are, so impossible to create new instances on those ‘cloned’ positions.

What you can do is creating a raspberry in SOP world (using copySOPs and so on) and then instance the full raspberry. Though this solution might be a bit troubling if you want to move the spheres as well.
Not sure what the best touchdesigner driven approach for this would be. (I would solve this by creating a vertex shader, but that requires GLSL programming and is a bit more complex)

Hope this helps

Cheers,
tim

thx, tim!
