Decals appear washed out when rendered in PhotoView. The attached image shows the orange ring decal (a PNG file with transparency) before and after rendering (right image). I've tried boosting the luminous intensity, but that just seems to make it more washed out (albeit brighter) to the point where it appears white. I'm trying to simulate a glowing orange ring illuminated by LEDs underneath, so I want the color to be more intense, the way it is on the left before rendering.
Any tips or ideas?
