Hello Again,

Just curious to see if there's a way to randomly flip the U coordinates or V coordinates independently per particle. e.g. I can set my fire flipbook particles to flip on the U coordinates at spawn time so some look mirrored.

Thanks in advance,

Hi Ryan,

Currently those properties are per renderer because of the underlying implementation of UVs generation. We have a ticket in 2.4 in https://support.popcornfx.com/issues/3359 to address UV scrolling as a whole for renderers, and your feedback definitely falls under that topic.

In the meantime, you should be able to change the billboard's billboarding mode to planar aligned, and simply flip the normal or side axis to flip the billboard per particle, which should have the same visual effect.
