Some experiments with normal-mapping Endless Sky ship images.
Basic usage:
. pipeline.sh wardragon.blend
Here are some example results of applying this directly to the blendfiles:
Here's an example where I used the blender scripts to generate initial images, put the flat-color image through the same GIMP modifications as the ES image, and then used that modified map to generate the spin. Untextured on the left, textured on the right:
This looked something like:
blender -b "pug maboro.blend" -P r_flat.py -o flat#.png -f 1;
blender -b "pug maboro.blend" -P r_norm.py -o norm#.png -f 1;
blender -b "pug maboro.blend" -P r_emit.py -o emit#.png -f 1;
python render.py flat1.png norm1.png emit1.png -o spin.gif
gimp "pug maboro.xcf" # in gimp, go replace the grayscale image with flat1.png
python render.py flat_tex.png norm1.png emit1.png -o color.gif
