Alpha channel in Tiff map causes hard crash, Enscape for Revit

  • Hi,

    I encountered a bug in Enscape for Revit a few days ago. I was using Enscape 2.9 and Revit 2018.3. In a project which always loads well into Enscape, I created a new Revit material and gave it new maps, including two greyscale Tiff maps: a bump and a glossiness (specular). I applied it to a few objects. When I started Enscape, it caused a hard crash: no mouse movement, I had to press the power button for a few seconds. After restarting the computer, Revit and Enscape, the exact same problem happened.

    I opened my Tiff maps in Photoshop and realised that one of them (the glossiness if I remember well) had an alpha channel. Effectively it had two channels: greyscale and an alpha. I deleted the alpha, saved and restarted Enscape, and now it worked fine.

    I guess this is low-priority, but could you look into it? It may be computer-specific. I'm using a MacBook Pro 16" with the Radeon Pro 5600M card, and the latest Boot Camp, Windows and drivers.

    Thank you,
