Textures disappearing in texture viewport shading (Cycles render mode)

Hey there guys! Pretty new to Blender but not to 3D. I am working on building up a city scene over the last couple of days when, starting today, I’ve been having problems with my textures not showing up in the texture viewport shading mode in the 3D viewport. I’m not sure what caused the change, but it happened while switching back and forth between wireframe and texture while adding objects to the scene. Little by little, the textures stopped showing up.

If I open up an earlier file the textures show just fine. The files are still in the scene as when I render the image, they render just fine. But they are disappearing from my viewport. and the more I work on the scene, the more they disappear.

Here are a couple of the textures hanging on. The other textures just wont display.

So, I am not quite sure what happened. Not am I sure if I should be posting this in the Materials and Textures forum, or the Basics / interface, or the Technical support forum.

I can work around this, if needs be. I will be using After Effects to render this city. Having the textures display here is more for convenience at this point. But I really would like to understand what’s happening. Chances are it’s an iD10T error. haha.

You guys are awesome, by the way! This forum always has the answers to almost all of my problems. Thank you so much in advanced for your help, and for all the help you have inadvertently given me!

Cycles has 100 texture file limit, one thing to consider. Other - your GPU memory amount and pixels belonging to your textures you feed to it. Cycles need all texture data in memory to do render calculations. You might run out of graphics memory. If there’s no nice pink color on textured objects, all texture files are found by blender - that’s not a reason then.

I am only using 20 textures, but I did find a work around, even though it is not quite an answer.

You had mentioned memory, so I poked around the User Preperences under systems and turned off “GPU Mipmap generation.” and my 3D texture viewport returned back to normal.

Not sure as to why this was causing issues for my textures to display as mipmaps are supposed to lesson the taxation on the system (granted more memory is stored on the GPU,) but it is a temperaty work around, and it does not seem to be taxing my system, so, at least until this project is finished (which is soon) this what I will do until I figure out what happened. Thanks for the tip on the memory Eppo!

I had the same problem with Blender Internal and turning off “GPU Mipmap generation” solved it too. Maybe it’s because this PC has an integrated graphics chip.
