Heres my recent character “Bopz” walking animation. I applied the naming example you gave so hopefully they are ready to use. If you need flipped green channel or anything let me know.

yoooo let’s gooo
Thank you for sharing this! It does however look like the diffuse and normals aren’t matching:
bopz_walk_normal_001:
bopz_walk_diffuse_001:
Look at how the feet are not aligned.

Are specular maps also a thing here? I know nothing, I just did a very quick search:-)
The textures are generic, they are what you decide them to be. You just need to have a shader that interprets them the way you want.

You’re right, I was off by one frame. Updated names and checked frames. Should match up correctly now. Let me know if you have any issues.
ps: some of the feet may seem a little different in shape, that is because a platform was masking the feet at some frames and not in the normal frames should be fine for an example and its something I can mask and fix later if needed to be exact. cheers

Thanks. They line up properly now. I put this into a sample project and uploaded here:
https://defold.com/sample-normal-maps-2d/
I guess my main concern with the Bopz character is that there’s all those specular highlights baked into the diffuse texture. I’m not an expert on these things but I supposed you’d want a specular map as well.

No problem. I went ahead and limited the baked lighting down to a very basic diffuse no harsh light reflections and shadows so that the lighting in this example can have more effect.
I will add the updated diffuse animation to the project and create a pull request on github.

Thanks. I think it is better for the purpose of this example. Next would be to build an example which also includes specular highlights. But what we have now is a good first example of what can be done.

Hey guys, I just tested it using the latest version (1.8.0) and I get a crash everytime on Windows 11.
On mac, it runs, but it doesn’t look the same as in the web sample. Looks like it’s ignoring the normal map, right?
Any ideas why it could be happening?

It crashes on macOS as well. 
Is there anything I can do to help fixing it? It looks like a bug, right?
Thanks. Jhonny has a PR with a fix here: Engine crashes when producing secondary uv sets by Jhonnyg · Pull Request #8893 · defold/defold · GitHub

So after a bit of experimentation with this concept, I’ve come up with a simple project that’s able to support normal and spectral lighting and can handle multiple different lights. It uses a lua module to help create/track lights and their values as they are pushed to the renderscript.
It supports directional, point, and spotlights as per this LearnOpenGL tutorial. The lights exist in 3d space and their effects on the sprites reflect (haha) that, and the lighting is attenuated. I’ll post code or the entire project (after cleaning and documenting) if anyone is interested. Here’s a sloppy example:

That would be great for reference. Let us know if you finally share the code. Thanks!
I’ve shared it already, here it is
