Hi, I’m a bit stuck with a certain effect I want to achieve.
I’m spawning some particles using the ‘Move to Nearest Distance Field Surface GPU’ module, however, I want to mask these particles by slope.
For a visual representation, in the video example, I want my particles to spawn on the floor, but not on the straigth walls, like the particles spawning on the cube side faces.
Thanks in advance 
So, using the out variable of “vectortonearestsurfacenormal”, and setting the axis you want to do a dot product with you can set up a “kill” parameter to limit the axis on what surface normal a particle will spawn. In my example I use colors to show which surface normal the particel is being aligned with.
Heres the setup in the particle system. I hope that this helps a bit
Yes!!! I believe that this method would be the best option for this case!
This is what I was looking for! Works perfectly! Thank you very much
