Keep particle geometry all the same visual size despite distance from the camera
I’ve got a thinking particle emitter sending out particles that end up sticking to scene geometry wherever they make contact. I would like to render the geometry (a circular disc) associated with each particle at the exact same visual size so that if I were to measure any two dots they would be the same pixel size. I think I need to tie the scale (somehow in xpresso probably) of each particle’s geometry to the distance from the camera. I have started to try and use pGetData and pSetData nodes in xpresso but with no luck so far. Does anyone know how to do this? What connections should I be making? Thanks in advance.
