layer blend 1 simply blends image 2 over image 1 (img 3) with the % you set and blend 2 does it reversed (img 4).
i belive you nead an sharp map for the soldier and version 3 or 4 for the road with not so much detail.
will look in to that as its probably simple as i have set the file loader to always go back to the default directory?
i have many ideas but little time
one thing you also can do i found is simply generate an normal map.
save it and the load it back in as an texture and run the calculation on the normal map.
after that to se how the normal looks on right texture simply load an new in so the model aint textured with the normal map any more.
cheers
ps
looks good the screenie but know wath you mean the road is to much shiny so test 3 or 4.
also experiment with the negativ value an low value gives an bright version and high value an dark.
negativ is used on image 2 , 3 and 4.
i also found that an layer blend of 50 will probably give the right img for the road as the details gets smerred between 1 and 2.
