How to import daylight res to mesh?

I’m trying to import the result file from a daylight study, redo the colouring and put in onto the mesh. Should be really simple. But the result comes out blurry. Looks like the uv-vector is wrong images.

I have tried different approached without luck. The result comes out the same way, Any input is appreciated.
