Hello, I'm trying to extend the surface of a whiteboard so you don't see the edge by adding a plate of the whiteboard beyond the edge and then using a mask to blend them together. It looks fantastic in the preview window, but when I render it out, the edge is still barely visible, like the opacity was set to something other than 100%. I tried using mask add, subtract, the plate as top layer, the plate as bottom layer, making sure feathering isn't affecting it. Rendering in 16 bit just in case. Nothing will make it be solid when it renders.
