There are no textures in the test file, i cannot reproduce this. However, you may want to test a recent build from builder.blender.org . Unfortunately there were a number of regressions in 2.72a, this might just be one of them ...

Hi Lukas,

Sorry, forgot to pack the texture.
Here is a blendfile with texture. test_regression_2.72a-x.blend

I tested with a 2.72 build from yesterday evening from builder.blender.org with the same negative result.

Just tried here on Linux 64, and I can confirm this worked in 2.71 (772af36), and is broken in master (179ad7d, and at least since 03ce9882).

@Sergey, I believe you're the one to summon here?

It seems that the issue is with the Filter type under the texture's Image Sampling. By default, it's set to Box which produces sharp textures but in your file it's set to EWA which is more blurry. Not sure if the default was changed in 2.72 but you can always change it back to Box.

Hi Moe,

I did some test with the filter settings. When set to 'Box' 2.71 and 2.72 produce the same sharp result, so no regression for Box.
With 2.71 EWA produces a slightly sharper image, compared to Box, be it with a very small margin.

So that narrows down the 2.72 regression to the EWA filter mode.

B.T.W. the default setting in 2.71 and 2.72 is as far as I can see EWA.
