I have a problem with a textured object in Cycles:

On the Render and Viewport I see a missing texture, but no texture is missing.

It seems not to be a matter of included or external stored textures. In both cases I have the same problem. The texture shows up correct in the Viewport after reconnecting the Materialnodes in the Node-editor, but after switching to solid Viewport Shading and switch back to rendered it shows the missing-magenta again.

The material nodes I used are the ones I always use and they worked fine until now. The problem seems to be independent from the used Blender version. Tested the scene in several versions.

How can I fix this?

To explain some uploaded Screenshots:

pseudo-missing texture: pseudo-missing texture

after reconnecting nodes: after reconnecting nodes

Update: I use the following Node-setup: Texture Coordinate (UV) -> Texture Group (DiffuseMap:Color-Data, Glossiness-Map: Non-Color-Data, ReflectionMap: Non-Color-Data, Normal Map: Non-Color-Data) -> PBR Dialectric Nodegroup (like the one from Blenderguru Tutorial) -> Output

After some more experiments with that problem i found out that the problem seems to be triggered by the Reflection Map. When it's disconneced it works fine. When i connect it then it still works in the viewport and it has the right influence on the used Material. After switching the Viewport Shading to solid and back i have the Pseudo-missing-Texture (Magenta) again.

Update 2: Tested a bunch of different connections between the nodes... but after quite a lot testing i can find no conclusion where the problem is.

Here are some more pictures of the node-setups that i tested: The ones that seem to work:






And the ones that bring me the missing-error:



Also tested mixing the Glossy and the Diffuse BDSF with a fix 0.5 value instead of using the Reflection Map... that was resulting in absolute random behavior. Sometimes it worked... sometimes not.

Found a solution! Converted the 16-bit png-files into 8-bit png-files. With these the problem doesnt seem to appear. But I'm still curious. Perhaps someone has an idea why that happens with the 16bit Textures.

  • $\begingroup$ I can't be sure (so I won't post it as an actual answer), but I suspect that the 16-bit images are big enough that they don't load the same way as 8-bit textures. It seems like the 16-bit textures are "timing out," if such a thing were possible. Almost as if it took too long loading the image, so Blender just assumed it was missing. This might be a bug, and it'd be worth searching the but tracker to see if it's been reported. $\endgroup$

I'll have a look at the bugtracker... to see if it's been reported. If not i'll post that in there. (Thanks Matt!)

  • $\begingroup$ This whole thing is quite weird. I went through a dozen of my hundred saved blends (old and new) and always used 16-bit textures. None of them had the missing texture shown. Have you tried to only convert the non-color data textures to 8-bit? $\endgroup$ Aug 25, 2016 at 2:47
  • $\begingroup$ Tried now... and it seems to work if i convert the non-color data textures to 8-bit. It also works with only a 8-bit normal texture and the rest 16-bit. $\endgroup$ Aug 25, 2016 at 3:20
  • $\begingroup$ How exactly do you do that? $\endgroup$ Aug 1, 2020 at 0:15
