3D Cylinder lighting problem

Hey guys, I've recently updated photoshop to the latest and now I seem to be having some 3D previewing issues. The first picture blow shows exactly how I like it before I start to turn the cylinder left or right.

After I double click the Cylinder_Material texture in the layers panel to put another graphic on this 3D cylinder. It comes out dark like so:

I tried resetting preferences, playing the lighting. Everything but no luck. Does anyone know what's going on here?

    For the initial issue, go to Scene properties and check remove backfaces.  That should get over the GPU black preview issue.

      @davescm wow thank you!  Opened this morning and did a quick 3D, sure enough looked really dark again.  Did your suggestion and it worked immediately!  Not sure I understand why anyone keep that feature enabled, would assume there's a good reason though.

      It shouldn't be needed, and was not needed in previous versions. It is really intended to cut down rendering by not calculating light paths to hidden faces. But in this version, the dark preview bug appeared and checking remove backfaces gets around it.

        Photoshop has a known bug in their sniffer script for Gpu and the work around... as you know, is just shut it down and reload it

        the issue you have is not the same as the op... the best fix is to force Photoshop to use the main Gpu on your system but to do that you need a Gpu driver that Microsoft can't replace whenever the mood hits them

        Having the same issue and it's frustrating!   My work PC was recently updated to Windows-10 seeing 7 is at end of life.  Rendering artwork for bottles the cylinder preset is great, but now for some reason in Photoshop 2020 when I enable the preset the artwork is incredibly dark.   Just like Phillip's image above, however this isn't after any graphic swapping.  It's the inital render when converting my flat artwork into a cylinder.   I think my old PC and sub-par graphics card are having issues with newer Apps like PSD-2020.   The only way I could solve is to close & re-launch Photoshop.

        it boils down to how much alike the two different images are... also things like Png vs Jpeg

        Photoshop is not designed to rendor in real time guys... to some amount Dimension is better at that if you have a good system

        after making a change you have to redo the lighting i.e, rendor again

        Unfortunately that's the same conclusion I came to. 😞  Ah well, I got it figured out haha.

        I am having the same issue on my imac pro. When I update the texture the IBL scenario changes for some reason. I have to go into the IBL and adjust the lighting and intensity each time. I have tried editing the texture a few different ways and each time it changes the cylinder lighting back to dark as shown in this example. 

         

        Is this a bug in the latest update?
