Hello out there!

So this is my first post in this nice forum. So....let's go!

I want to build up a little TP Setup where particles shoot on a polygon object. That's not a problem. Now I want, that the Polygons, that were hit by a particle should be deleted/hided or fall down on the ground. Anyway, the particles should destroy the Polygon object and I don't know how I can seperate those polygons from the whole object. Can anyone help me out?

Thanks Guys!

Here's a setup in which each poly is deleted as it is hit by a particle. There's also an option to add each poly to a selection tag upong being hit. This and deletion are of course mutually exclusive. Polys can be added to the selection tag cumulatively or it can have only the last poly hit. (Note that if all selection tag polys are deleted, the object will be forced to wireframe display due to the texture tag hosting an empty selection tag.)

User data are on the XPresso tag and include link fields for the object and selection tag.

Thank you very much. This is a nice script. I'm going to check it out right now.

Thank you!

The file above has been updated to fix whacked poly identification with certain meshes. This latest version also introduces support for triangles.

Here's another example using particle-driven poly selection with the Extrude Object.
