When an object has a ‘transparency’ texture and you apply a Gloss Finish to it, the transparent parts behave very oddly.
Far away from the ‘glossy reflection’ they are transparent.
The closer the surface gets to the ‘glossy reflection’ point, it the more OPAQUE it gets. (this is wrong)
The TRANSPARENT part should STAY TRANSPARENT, and should not gradient from transparent to opaque.
When I disable the COLOR map, then the DARK BAND goes away, so the gaps now transition from TRANSPARENT to OPAQUE WHITE. (this is still wrong)
In my example below, notice the spaces inside the metal Texture. At the far edge they are correctly transparent, but at the center of the highlight they are completely opaque and white!
This is in the RENDERED view mode in Rhino SR9 (5.9.40609.20145, 06/09/2014).
Is this a known bug for transparent textures on objects?
Also, enabling the ‘Bump’ texture (actually a Normal map) gives very strange results! (I can zip the files and send them to you if you’d like to take a look).
