v2.77a - Textured object not updating when manually changing UV coordinates I am experimanting with texturing simple objects. My idea is to use very small textures. So I manually resized and moved the UV coordinates to be inside the pixels. You can see on the screenshot I have uploaded.



Unfortunately they do not seem to update. I have zero idea why, any hints or tips will be appreciated.

[Edit]: I have put all obj faces that should be red over the red in the texture (neatly arranged without overlapping). I have moved all the faces that should be black on the top (this time I did not arrange them as it did not help with the red). 

I expect all front and back of the cross to become red and the sides to be black.
If you're using Cycles, you will also have to have the image mapped to a material node (like a diffuse or something) before it will show up properly in the Viewport.

Try setting up the material nodes the way they should be, and see if the texture updates better.

The other thing that might be causing this is if your texture is set to repeat. If it's repeating, then when you move a UV island outside the red area, it will still be red. It might be updating... you just can't tell.
