In my scene in Maya i have electricity and fire coming from a couple of objects. I rendered them and everything was fine so i put these on a display layer to hide them before adding particle clouds, however, my renders are now completely black. No objects appear at all unless i have my display layer with fire and electricity visible, and even in this instance the cloud effects are bright blue, despite having changed the colour. I'v used Maya Software and MR with both results being practically the same.
If any one could help me in fixing this i'd really appreciate it. thanks.
