Uving

I have U'vd ll of my lod's now, i developed my own method.

-step 1 manualy lay out half of the model nicely so your happy
-step 2 use the unfold tool to just clean up all of the nice work on the half that ive already done.
-step 3 use a checker node applied to a shader and assigned to the model to test that half
-step 4 take a snapshot of the top right uv editor screen and apply it as a colour to that shader.
-step 5 use the image of the other side to lay out the un-done side.
-step 6 texture and test! should work fine if you manualy layed them out ok :)
