I am new here, so excuse me if this is the wrong section/an obvious answer.
I have recently been following along in the Nature Acedemy's videos. I encountered an issue in the flower section of the grass tutorials (week 1). For some unknown reason, my particle system that renders a flower group (which were created on a separate layer) as black halos. The flowers are there, however without any material. They each have their own separate materials, just as solid colours.
Any help would be graciously appreciated.
