@lukad Oh yes, sorry.

If one want to get particle info for now, you can use the following expression to evaluate the depsgraph:

bpy.context.depsgraph.objects.get(object.name)

This object can then be used to get the particle system and get its data as follows:

Node Tree

Yes, we are aware about this issue. Unfortunately, this is related to Blender itself, so we will implement a fix as soon as this gets fixed in Blender.

Should this be reopened? I see that the fix was reverted in 6158c32ffcb19b70303dfb8cd271acc9d3290e5b and it's still broken in the blender2.8 branch.
I also tried using the fix by checking it out directly and it wasn't working for me.

@OmarSquircleArt
Thanks for the solution and this project! I just got an another question, If there is a way to add a GroupInput between Expression and Object Input? I want to control the source object. 😄
