Sprite Illuminator + Spine Workflow

rxmarcus

I'm wanting to look into using Sprite Illuminator to create the normal maps for my spine characters. I've seen a few posts around the forums of people mentioning they use Sprite Illuminator and I'm hoping people could share their general knowledge of the work flow in regards to using Spine and Sprite Illuminator.

All I can think is that the exported packed texture from spine could be brought into Sprite Illuminator and you could paint the normal map for each individual piece of the skeleton? Is there a better way?

Any thoughts / tips in this regard would be greatly appreciated!

The texture packer that comes with Spine should be deterministic as long as your image dimensions don't change.
For example, if you packed Spineboy's images. And then had an alternate version of those images without changing their size, it would pack with the same layout.

This means you can have the normals generated per image, then pack them into their own png. This allows both the diffuse and bump textures to line up correctly.

I'm not sure how Sprite Illuminator works (if it allows you to easily generate normals for a bunch of parts at the same time.)
If not, you might be better off generating normals on the packed atlas.
