Generate custom sample set
Generate custom sample set
I'm a bit lost here.
While the "Generate Sample Set" node only emits once (if you set it up like this) I seem to miss the point of how I'm able to do this with the "Add point" node by itself.
How do I set up a particle emitter which uses custom input (point location), but emits only once at the start frame and then not any more?
Cheers

Get a Current Frame node and an if node. Plug the Add Point node into the True port.

That's something I tried. But I didn't succeed with frame 0, only with frame one and above. Can't I emit on frame 0 or did I set something up in the wrong way?

Re: Generate custom sample set
Are you trying this on a simulated ICE Tree? If so, you could try "Execute Once"...
And yes I think emitting in a simulated tree normally starts at frame 1, but I'm not 100% sure.

(Quoted from here)Note that ICE particles are actually emitted only starting the second frame of the simulation frame range.
Stay safe, sane & healthy!

Re: Generate custom sample set
Frame calculations start on the first frame it can calculate stuff for which is not frame 0. If you want frame 0 then you need to set your simulation environment to start at -1.

Thanks guys!!!
Yes, simulated ice tree.

Re: Generate custom sample set
Build a simple trigger. By default all custom attributes inits with 0 ( identity in case of matrices ), so you can use it and execute anything independently of your first frame value
