So firstly, for the color issues, you can use the ‘color overlay’ layer style in Photoshop to easily adjust colors of your mesh then just save as png and reload with previous texture.
Secondly, for rendering, the texture that was in your model for some reason wouldn’t render the transparency. The new texture I added did. Didn’t look that far into it but there’s something wrong with that particular image (for me anyway). Seems to render the transparency fine after swapping out.
As for the UV, I don’t have fancy UV tools like WrapR (and couldn’t use it anyway as I’m on a Mac. For this text, I set the copied the mesh 3 times and rotated for front, bottom and sides and made sure texture was set to ‘projected’. You can see some warping at the very corner where the sides and backs come together so could do one more projection at 45 degrees to fix that spot.
Hope this helps.
