Rhino WIP 7.0.20203.15405, 21.07.2020 ▶ System info PNG alpha channel transparency is not working. I think that two builds ago it was working. Maybe by coincidence but I noticed it stopped working after @andy made some changes discussed in the thread Refreshing Textures got slower & annoying - #12 …

I noticed that 8-bit PNG texture files looks like they have almost inverted colors or are completely black. The same texture files opened in the Photoshop or Windows look correctly. [image] 8 bit png file: [kolko] 32 bit png file: [rhino png test] test file: rhino png test.3dm (203.6 KB)

I can duplicate that. V6 is okay, V7 is not. https://mcneel.myjetbrains.com/youtrack/issue/RH-59602 Thanks

Thank you for looking into this problem. The problem seems to be fixed at the first glance, but there are still some issues. Transparency is ignored when it comes to casting/not casting shadows. Rhino 6: [image] Rhino WIP: [image]

New bug: https://mcneel.myjetbrains.com/youtrack/issue/RH-59754

@Czaja I’m having trouble repeating this new issue. How does this file look on your system in V6 and V7? rhino png test V6.3dm (246.0 KB) Make sure your “Rendered” working display mode is set to defaults

@John_Brock , It looks that it was my fault, my presumptions based on the previous bug was wrong. Sorry for the false report. I was experimenting with the view modes and didn’t realize that I set transparent objects to always cast shadows. [image] [image]

I have cancelled that second defect report. Thanks
