Hello. I'm now trying to make my image such that the background can be seen through some glass (and fire!). I've tried adding a mask and then changing the opacity and using the brush tool. But doing that seems to allow me to 'see' through the glass (via the mask) to the green background, but then I loose the edges of the glass, so that it doesn't look right. The image i've attached is pre me trying the masking. Any suggestions how I can do this without loosing the effect of it being glass? Thank you
