I am having a hard time getting PNG's to become transparent on clear areas. This is in accurate mode. Any thoughts? The transparent areas end up rendering as darker areas with white speckles.
I was trying to do the same thing yesterday...multiple .png's with transparent backgrounds on the same part (an interactive button).
The artwork came from Illustrator, so I tried increasing the resolution to 600ppi and even re-saving in Photoshop to no success.
Ultimately, I had to fire up Maxwell to get it done, but will circle back and let you know if I make any progress because I really want to use visualize more.
Hi Chris,
I tried a quick test here and I'm not seeing the same general issue. I created a basic transparent background, decal image, in photoshop and I don't see artifacts behind the transparent area as you've shown. I tried both Fast and Accurate.

Hey Chris,
I took some time to try some different options to see if I could improve the alpha ghosting. It looks like the substrate material affects the label. However, I did find that exporting as a TIF gave better results.
In this image, the big power icon is a PNG, the small TIF, and the white is a PSD (didn't acknowledge transparency at all) - over a "Soft Touch Black" material:
In this image the material was changed to "Smooth Black":
I'll continue to try to improve my workflow, but I'm wondering if the normal map causes interference with the alpha?
Best,
Dexter
The second image, small power icon is perfect. Looks really crisp. I will mess around with the settings.
If you drop the roughness to 0 of the base appearance with a normal map, the decal transparency ghosting goes away. In fact, the higher roughness values negate the normal map's effect.
At least, on the work I'm doing - YMMV.
Hope that helps on your end!
