Ahich is more efficient, cutout transparency or translucent transparencies?

If I were you, I’d build a solid mesh with a solid material for the inner shapes of the clouds, and then build various fins/cards for the edges and whisps, that use a translucent material.
Make that happen, the measure performance. If performance in a real scene is okay, then you’re done!
The benefit of the opaque inner body is that that will render using the optimum static opaque geometry path. The second material for the transparent bits will then come after in the translucent pass, and as long as you don’t have too much overdraw, you’ll likely be fine.

So basically like the cloud int he second picture? Awesome, thanks ill give it a shot.
