@troubled its a particle emitter, when I unchecked the camera option I couldn’t see the particles, but I uncked transmission.
Ok thanks for all the tips guys. The current pic is with the bounce up to 12, I also added a couple more transmission planes, and changed the glow a bit, this is a very low sample version (50).
I don’t think it’s perfect but I’ll leave at that so I can move on to learning other stuff. Actually learned loads from this, first time using cycles, and first time compositing and actually pretty much the first decent thing I’ve made in blender (even if it is from a tutorial), thanks for all the help guys.
