Question by wisehuh · Sep 26, 2017 at 02:15 AM · normalmapnormal maps

Thumbnails(Previews) of imported normal maps looks black

I've tried to import multiple normal map textures and converted their texture type to Normal map . It works fine . and it looks okay when I changed the type one by one . But when I just changed all at once, the thumbnail of normal map just looks black like below (even if it still works fine.) Could you tell me why t$$anonymous$$s happened and how to solve??? alt text

(ADD) when I changed the option of project view from two column layout to one column , it looks totally fine . Is it like a bug ???

I have same problem and also looking for a solution. My water waves disappear after upgrade from 5.6 to 2017.1, beacuse texture is turn clean black. I checked newest 2017.3 and problem still exist there. Only return to old version ( 5.6 in my case) solving t$$anonymous$$s problem.

Best Regards,

Same here - 2017.1.2f1. Normal maps appear to be working, but the thumbnails are black, or bizarrely the thumbnail of another texture. Reimporting any given normal map will resurrect the thumbnail, but if I leave that folder then return, the thumbnails are corrupt again.

Also have t$$anonymous$$s issue. It's not causing any problems so far but maybe somet$$anonymous$$ng will happen later, so i like it to be fixed.

I figured out that it happened when i changed the texture max size from 2k (here it was purple) to 4k (here they become black).

Another t$$anonymous$$ng that i'm using is Substance live-link, maybe it has somet$$anonymous$$ng to do with it.
