How can we scatter 2d multiple times (with different parameters) so we can also check for collisions between individual instances? [image] @pcallender @dennis.lynch @jiehanw

The other thread is about collisions with racks and static objects. This thread is about collisions between instances.

Right - but i initially thought that the same thing might be leading to both issues (not using rep.sequential) but this is not the case for the other thread. it may be for this - can you better describe what you are doing here - are you trying to first, run some scatter (say with non-colliding “wor…

Yes - currently I try to achieve that by supplying different seeds.

Got it - then you’ll want to do something like this - with rep.sequential(): with items1: rep.scatter2d() with items2: rep.scatter2d(no_collision=items1) ` The seed shouldn’t matter so long as you do collision checking. if it samples the same seed on the next scatter, it w…

How do I do rep.sequential() in the Replicator YAML?

good question. Here is an example snippet that should work (it works for me, let me know if it does for you). Note how the scatter nodes use they same seed (they are not specified) but the second scatter with the cubes does not overlap the spheres. If you comment out the “no_coll_prims: [spheres]” …
