Bug 510: Optimal UV paking?

What do i do wrong?

thank you for the post. We see the problem. There is small utilization so that the resolution could be smaller to get better utilization. We will fix this issue. You can meanwhile use RECONSTRUCTION -> Unwrap tool and change the maximal resolution to smaller value. You can check utilization in the model detail panel (just click on the model in 1Ds view of the left panel) before the texturing after the unwrapping. This way you can unwrap the model multiple times to achieve preferred properties before the texturing.
