This may be old news for most, but I just discovered that exporting the model in Unreal A-pose seems to fix the weird shoulder issue.

Seeing that his Blender auto-setup tool become the main choice for RL advertising it on their website + youtube... And seeing the quality of the work so far done in Unity, I'm assuming he's the chosen one to provide a performant auto-setup tool for Unity, at least for HDRP so far :)

Amazing work on the HDRP shaders - looks awesome. 

Are these something you are considering releasing (on the asset store or otherwise)? Would be a huge assistance for those of us that aren't very...shader-ey... to be able to replicate what Reallusion provides even remotely closely...

Thanks a lot for sharing

Looking up by name in editor time (or at Start) is completely fine, I just didn't want that for blendshape manipulation at runtime. Your tool is going to help me quite a lot here, thank you

The tool menu functions are completely independant of the shader and material setup so I can show you that now:

https://soupday.github.io/code/MeshUtil.cs

(It's editor code so it needs to be placed in a folder named 'Editor')

But I pretty much have to do the same thing, look up the Blend shapes by name to get the index.

The only thing I can suggest is that you create a lookup table that lists all the blend shapes by name and that contains a dictionary of each Mesh object and the index of the blend shape. Something like:

public class BSLookup
{
    string shapeName;
    Dictionary<SkinnedMeshRenderer, int> indexCache;

    public void SetWeight(float weight)
    {
        foreach (KeyValuePair<SkinnedMeshRenderer, int> pair in indexCache)
            pair.Key.SetBlendShapeWeight(pair.Value, weight);
    }
}

public List<BSLookup> lookupTable;


This way you only search for the blend shape name once, but you will need to scan the entire character first to fill in the lookup table.

Ok I definitely would like to know how you prune blenshapes :D

I created this "bug report" https://www.reallusion.com/FeedBackTracker/Issue/Blendshapes-inconsistent-between-Body-and-Beards-Tested-with-EXplus-facial-profile 

Which is exactly about the inconsistency of Blendshapes between characters.

There is also the problem within CC that the "fix eye blink" feature doesn't fix it on the new EX+ blendshapes

I'm creating an expression manager in Unity, to easily animate CC3 character's expressions.
Basically animating all similar blendshape on the face from the different meshes (face, beard, mustache, brows)

But performance wise it's an issue to have on some meshes the blendshapes Smile Left at index 40 et on another mesh it's at index 41 as I have to lookup the blendshapes by name first and then by index

Would you be keen to share this Pruning script privately if I PM you? It could help me understand how I could maybe organize the blendshapes properly for a larger scope of use

Like my Blender Setup add-on, it's a personal tool that I will make available, when it's ready.

My original intention was to make a pipeline for CC3 -> Blender -> Unity, I would bake the textures in Blender and set them up in Unity, but then I discovered baking the textures in Compute Shaders was 10x faster in Unity, so it's become a direct CC3 -> Unity setup.

Looks like a good solution to it.

I'm sorry but I'm unfamiliar with the work you've been doing on this tool, is it some sort of asset that is or being made available somewhere?  Or is this just a personal / proprietary tool?

Well... that works.

I've noticed different characters have different sets of blend shapes and I did think at the time that it culled the inactive blend shapes.

But if it isn't culling them or they are such a small influence that they don't have any visible effect, it should be possible in a script to build replacement meshes that only keep the blend shapes whose vertex delta's pass a certain threshold. I've already written a function to copy blend shapes from a source mesh into a new mesh and replace it in the prefab, putting a threshold condition on them is almost trivial. I can put that in the tool menu. e.g. select the character then: Menu->Tools->"Prune Blend Shapes" (assuming it works)
