I'm pretty sure it's the Y (green) that needs to be flipped when converting between opengl and dx
also blue is completely lost so you either need to recalculate it, flip it or fill it with white/1

#define BlendOverlayf(base, blend) 	(base < 0.5 ? (2.0 * base * blend) : (1.0 - 2.0 * (1.0 - base) * (1.0 - blend)))

half3 DecompressRawDetail( half3 vNormal )
{
    // Assume that all normals are in DXN (ignore the Z)
    vNormal.xy = -vNormal.xy * 2 + 1;
    vNormal.z = sqrt( 1.0f - saturate(dot( vNormal.xy, vNormal.xy )) );

    // The output normal is signed, but may not be normalized depending on texture values and BumpScale
    return vNormal;
}

half3 BlendDetailMap(half3 _baseNormal, half4 rawDetail)
{ 
    _baseNormal.z += 1;
    half3 detail = DecompressRawDetail(rawDetail.rgb);
    half3 r = _baseNormal * dot(_baseNormal, detail) - detail * _baseNormal.z;
    return normalize(r);

}

float2x2 RotationMatrix(float rotation)  
{  
    float c = cos(rotation);  
    float s = sin(rotation);  
 
    return float2x2(float2(c, -s), float2(s ,c));  
}

Your assumption about Y axis is correct. DX has it's upper left corner as zero, while GL has it's lower left corner. So their Y axis normal coordinates point in opposite directions.
Your idea to fill z coord with 1 is not particularly good. This will lead to normal's flattening.

Hey Custard would you mind helping cleaning up the nodes for this or do you have a proper nodegroup for it? The nodes are
Also I wanna combine the normals into one texture (so no need for the mask and nodes again at a later time) but no idea how to :c

For consolidating normal map texture the Cycles baker should make this very easy, it's a method I've used often in my own assets creation at the end to make it a bit of cleaner package.

I feel like I'm missing something here, the baked normal has no details at all, prolly my nodes, imma watch some blender tutorials, anyway thx for the help Custard
(as for the nodes, i cleaned them up so ig it's OK now)

EDIT: not sure what happened, made a new blend file and it just worked.. now I have a detail normal map for thunderbird's helmet which plugged into your shader's detail normal input works perfectly, I still need to clean it up and add a few things but it's looking good (for portability)

Huh, well I'm happy to have a look but I don't think there's a lot I can help you with Floxay. You seems as good or better than me about the materials. For consolidating normal map texture the Cycles baker should make this very easy, it's a method I've used often in my own assets creation at the end to make it a bit of cleaner package.

Not sure if you've done bakiung in Blender before but here's the process. You can ask the baker to take the final state of the normal map as applied to the mesh and put that on a texture for you.

- Go into the shader you want to get processed normal map of.
- Add a new image texture node. This isn't going to be plugged into anything it's going to serve as the target image to bake to, as such it is important that this one be in a 'selected' state when you hit bake. That means it's the node with a highlight around it that you've clicked on last.
- Make a new texture there by pressing new, make the resolution correct and for normal you'd probably want no alpha and 32 bit float.
- Set the color space of that image node to non-color. The color space setting on the node affects the bake result.
- Go Render Properties tab, with it set to Cycles. Change render sampling to 1 sample. In the case where the baker isn't actually taking input from lighting then 1 sample is as good as 1 million sample, but it still wastes time generating as many samples as you set there.
- Down in the same Render Property tab can be found the Bake section. Set bake type to "Normal" and chose margin. Setting a very high margin counts as infinite dilation basically, and low margin + clear image will fill flat normal color between islands.
- Then, with your target image node selected and the object itself still selected hit bake and it should give you out the perfect consolidated normal map.

If the object has multiple shaders on it there will be a message saying no selected image in those other shaders, which is ignorable, OR you may accidentally had an image still selected in one of those other shaders, in which case it probably give a circular dependency error as it tries to bake onto a texture that's already being used by the shader.

Then in image editor section in Blender visual confirm the results and save the image out. If you start adding stuff like modifiers or mesh edit it can end up adding artifacts to the output, but otherwise the results always seem perfect to me. Not like the baking pains you might get when doing high-to-low poly and worrying about cages and rays and all that.

By the way that eye in your render looks like the official eye, did you actual manage to assemble a shader for it?

I have found combining two normal maps and then baking those on Blender gives bad results, as seen in my old Shadow of the Tomb Raider models on DeviantArt, for example, the lack of sub-surface scattering on lips. I'd rather use something like Photoshop and CrazyBump to combine multiple normal maps.

I followed this guide and it instantly gave me better results (Photoshop only):

It is the official eye with the mouth yes, I just played around with an older eye diffuse Luxox left us

I'm pretty sure that is fixable and just a matter of figuring out the correct node and bake workflow for it. I, personally, will definitely never go with the PS method, it looks like a pain in the ass sadly, I'd rather just fix the normals in blender (if they are actually broken which doesn't seem to be the case for me, rn just doing the mixrgb 0.5 mix and normal strength on 2, it seems to work i guess?)

We can consider that combining normals map in Blender is an ambiguous action. Baking is by-the-by, cashing in of whatever work you've already done with the nodes. That work can be mixing normals with a MixRGB node in 3 seconds, or running them through a series of math nodes based on a presumably 'correct' method.

It was no long since I took the time to research the subject and get myself such a node group. I read a few papers and threads of the subject, and tried about 5 different node groups. They all either made mistakes that made the situation worse due to too little field testing or were imperceptible from a simple overlay mix, until the last one. As soon as I plugged in the last one I could see how overlay was inferior, the advanced method made the overlay look slightly blurry or flattened.

I will link it here so that you can use it if you want to and see if you like it. An empty .blend file with the node group for appending from. Of course using it without bothering to bake or combine any textures is the most convenience method of all.
