I imported an .obj file with a texture, originally exported from Reality Capture. The texture shows completely Black(material preview). I Tried importing the same file into the Blender on my Windows laptop instead of my Mac. ..and the textures are working fine there. Tried it with .fbx as well, and it does the same.. PC shows, Mac does not. I would really appreciate if anybody can tell me what's going on? Im sharing screenshots.. B.

On Mac textures show black

On Mac

On Windows textures show fine enter image description here

  • Are we missing one picture? Is the mac using an AMD GPU? – susu Jan 19 '21 at 20:18
  • Susu, Yes AMD Radeon HD 6970M 2048MB. Both Pictures look like album covers.. should I just delete the pictures.. is it a bug? – Boris Jan 19 '21 at 20:21

    You show two pictures that are the same image, so it hard to understand the problem. Also, macs and AMD are the worst platform for blender. On top of that AMD's drivers have been having a lot of problems lately. Try downgrading to an older version or enabling high quality normals. https://blender.stackexchange.com/questions/204297/amd-gpu-material-in-material-preview-mode-and-rendered-mode-is-entirely-gra – susu Jan 19 '21 at 20:25
  • I corrected the images. The iMac is from mid2011, I prefer it because it has a big screen. Checked the link. enabling high quality normals didn't work.. looking how I can downgrade the GPU driver to an older version on a mac.. thanks – Boris Jan 19 '21 at 21:23
  • Try clearing custom split normals https://blender.stackexchange.com/questions/175080/material-is-always-black-and-on-cycles/175127#175127 and https://blender.stackexchange.com/questions/120675/object-appears-black-while-rendering-while-other-objects-look-normal/120677#120677 – susu Jan 19 '21 at 23:05
  • Are the mac and windows running the same version of blender? – susu Jan 19 '21 at 23:12
  • It looks like if you have a thunderbolt port you might be able to use the Mac as a secondary screen for the PC. I actually do IT for a living, so I just happened to remember something about this: https://www.techjunkie.com/how-to-use-an-imac-as-a-monitor-for-pc/ – Allen Simpson Jan 20 '21 at 00:37
  • Sorry Susu, clearing custom split normals didn’t do the job either. I am using 2.91.0 on both computers. Additionally, I installed Blender on a newer MacBook Pro and opened the same Blender file there, and it shows the textures. Following this, I uninstalled 2.91.0 from iMac and installed the latest 2.92.0 version. Unfortunately, textures don’t show again. I guess it's really the GPU then, isn’t it?. Bummer.. the old iMac is actually working wonderfully with Blender. – Boris Jan 20 '21 at 22:37
  • Hey Allen, Thank you for the advice. However, I’m confused. 
Below I’m sharing both of my computers Specs

    Can you please tell me if I can actually use my iMac as a monitor for my PC laptop? If so, do I need any specific cables or adaptors?

  • I solved this issue by decreasing my resolution to 1920 x 1080 from 2650 x 1440. It worked when I reassigned my image textures. It prefers working with smaller sized textures (MB wise) but it works. Good luck to those who have the same problem. – Boris Jan 26 '21 at 18:54
