2.8: Disable mipmaps, view textures Up until 2.8, I was able to disable mipmapping in the preferences (which for some reason, disabled texture filtering), however this option is now unfortunately missing. I understand I can use nodes to create unfiltered renders but I need this for pixel-perfect editing as the models will be exported.

Another issue I have it that textures now longer show up in 'look dev' mode without a material. (previously alt-z). 

Until I can fix these, I have to revert to 2.79a. Any help would be very much appreciated.

Thank you
Under the shading tab, add an environment texture and set it to closest and connect the node up.
