Normal map lighting for 2D Pixel Art sprites

The Defoldmine
24

In the Defold 1.6.4 beta we’ve added support for multiple textures for the sprites as well.

It allows you to set e.g. a diffuse atlas and a normal map atlas to your sprites.
Use naming conventions to keep the image names easy to use in your atlas.
E.g. for the first frame of an animation, you have a diffuse and normal image:

hero_diffuse_1.png
hero_normal_1.png
hero_diffuse_2.png
hero_normal_3.png

Then it’s easy to rename these frames in the atlas using the “Rename patterns”.
Use “rename_patterns: _diffuse_=” and “rename_patterns: _normal_=” to make the names the same in the atlases.
It is important for the image names to be the same, as lookup is being done between atlases using the key “myanim/imagename” into the other atlases.

I hope this helps, and let me know if you have any questions!
