I dont know if the title is clear enough
I am doing an animation with a milling tool that goes on a specific route (up and down ) over an over again and everytime the tool crosses the mold it emit particles - chips of metal.
Instead of doing keyframes for everytime it cross I decided to do some xpresso that tells the emitter to start emitting when Y axis of the tool is below a given number (compare node) my problem is that I need the emitter to emit between two points (higher point an lower point), this way the emmiter is emitting particles until it reach the lower point and stop until the tool go back down the next time. I tried to find an “and” node to attach to the compare node and I have found none.
I need the emitter to emit only on the way down
Please try to help
thanks in advance
