Surface Test Possible Issue

[rjanders0003]

It's expected.

Once you changed the test to volume outside, you immediately sent out all the particles to second event.. and they stay there.
So when animation is going on, all particles are in second event, and unable to detect anything (they are no longer in first event), unless you add another surface test to second event (where particles chilling and drinking beers. )

Hope that helps

Thanks

I should have realized that !! - The deeh moment, is I did add it to 2nd event to test that, but forgot to pass it onto a 3rd event to see color change - Sometimes lack of thinking happens
