Image planes as rendered. Images are .png although .jpg does not work either.
Particles in viewport
Basic settings so no idea what’s up.
.blend File
Nevermind I duplicated a plane with cycles camera visibility unchecked.
I noticed this post by chance after I asked a similar question. I wonder if you’re doing the same tutorial. Anyway, after reading your post, it occurred to me I should just use another plane for my snowflake emitter. It worked. I still have no idea why the other emitter plane wasn’t emitting flakes that were rendering. So thanks…
