I try to color PRT Volume by Gradient Ramp and measuring distance beetween particles and Point Helper where the helper is located in the center of PRT, thus at least one particle should be close to zero length between, but if you look at Debug List, minimum length about 20, I dont know whats going onhttp://clip2net.com/s/7cBhbK
The InputPosition channel in Magma is in Object space. Unless the PRT Volume is at the world origin, or the checkbox “Use World Space” is checked, the particles will report their position relative to the origin of the PRT Volume and not relative to the world origin. So if your PRT Volume is offset by about 30 units from the world origin, your magnitude of the subtraction will always be off by that amount. The PropertyQuery from external objects always reports the World Space position. So you can either convert the InputChannel:Position -> ToWorld or the PropertyQuery:Position -> FromWorld to bring both values into the same space.
