Exact steps for others to reproduce the error
- Switch to Cycles renderer
- Set up a simple material as shown in the attached sample: Plane with image texture, set extension mode to "clip", translate the U coordinate by 0.5.
- View the scene in the 3D viewport with Rendered mode and Material mode.
Expected: Texture should be clipped in the Material view, just like it is in the Rendered view
Actual: Texture isn't clipped, but extended. Setting the extension mode in the Image Texture node has no effect on the Material view.
I like using the Material view in the 3D viewport to work on my diffuse textures because it's very fast, so it's annoying that I can't use it to see what a clipped image texture will look like.
