Hey !
I have a boolean operation on a 3D text and I want to emit partciles when the text disappear due the boolean intersection of a sphere.
I tried to do a boolean operation and emit from that but it doesn’t seem to be working, I need to animate a region and tell to blender to emit partciles only in this region of the mesh ?
How can I do this ?
Already many thanks.
See Example below that was created in Houdini.
The guy in the video uses Dynamic Paint but you can also simply create a vertex group on the Emission object with all vertices in the group. Then add a mask modifier and use this vertex group with the “use vertices that are not part of region defined” button aka the reverse button.
the boolean method is not the most optimized ( even in houdini it’s not the most optimal way ), normally you would use a texture that you can emit particles from and another delayed one that will mask the object, there’s no heavy calculation here ( if you have dense mesh )
Continuing the discussion from Emit particles from boolean operation?:
Thanks for the helpfull tutorial !
