Delete selected particles and their trajectories I have a (baked) particle cache, I can enter &quot;Particle Edit&quot; mode, but I can't seem to be able to delete selected particle trajectories. Can it be done? How?
Example
I've created a minimal example: there's an emission object and a &quot;kill particles&quot; collision object. A &quot;dupli&quot; object is added just for visibility.

Let's say I want to remove retroactively all the particles that aren't killed by the obstacle.
Attempts
Several other related questions have answers that mention Select+X and Select+Del (in Particle Edit mode) as ways to remove trajectories or trajectory points: it wasn't specified. I'm unable to do either.
In &quot;Path&quot; select mode, I can't seem to select anything, with either  RMB or C+LMB:

In &quot;Point&quot; select mode, I'm able to select trajectory points (but I wouldn't know how to select all the trajectories: there's no Ctrl+L functionality). However, X and Select+Del show no effect.

Same for &quot;Tip&quot;:

The &quot;cut&quot; brush also seems ineffective:

File
you can download my minimal example here:
As far as I know, there is no way of deleting individual particles.

BUT - possible workaround:
In particle edit mode, deselect "Keep Root", hover your mouse over a strand, press L to select the whole strand (you'll have to repeat this for every single strand) and move them somewhere else. They'll still be in the scene, but out of the way at least.
