Is the character import window still open when it does this?

The window holds onto a reference to the currently selected character and materials, it could be recompiling shaders for it when the scene lighting changes, even though it's not technically in the scene.

Closing the importer window should release the character data and could/should stop it recompiling the shaders.

Thanks for the reply, I'll try deleting it and restarting then.

Hi Victor, 

 Many thanks for the quick reply! I think the importer window is open, that would explain this. I'll try closing next time this crops up. Many thanks!

 Cheers!

P.S. love these tools! Amazingly realistic characters in Unity - especially with HDRP!

Hey Unity Auto SetUp Fans!

 Just wanted to share a clip that shows the hair physics you can get in Unity >out of the box< with Unity Auto Setup 1.50 for HDRP and available settings. This is using a CC4 avatar with elements from hair builder. The cloth physics components that Soupday automatically adds creates this. I thought i would have to go into blender and add bones and do more detail - but being able to have this as a baseline is very impressive.

I have a support ticket and Rampa wants me to ask about it in here. I can't use the unity cc4 addon because my developers don't want to use up the extra space in unity just for a character importer. I do have an issue though. When I export the character from CC4 to Unity export I get a -90 rotation. Is there any way to get this to come in without the rotation???

Changelog:
1.5.1

• Character Build no longer creates and adds a default animation controller due to bugs in Unity 2022/2023 causing memory leaks when applying animation controllers to prefabs.
• Instalod and other renamed object/material name matching improvements.
• Cloth physics fix for extracted non physics materials using 2-pass hair.
• Shaders recompiled for URP10/12/15.

1.5.0

• Animation player system rebuilt to remove AnimationMode and operate in play mode (in Editor).
• New system includes foot IK preview, variable speed and camera bone targeting and play mode operation.
• Optional (WIP) HDRP dual specular shader added for HQ skin. (Enabled in the import window options)
• HDRP mask detail mask correction. (Export from CC4 not using correct micro normal mask)
• HDRP lighting fix when first loading preview scene.
• Batch processing window added.
• Physics sphere collider support added.
• Import procedure now processes all <character_name>_Motion.Fbx files with the character.
• Fix to character build crash in Unity 2023.1
• Fix to Diffusion profiles not saving to default volume asset in 2023.1.

One small feature request: It would be nice if AnimRetargetGUI.WriteAnimationToAssetDatabase would update existing animations, instead of recreating them. The reason is: If something is referencing the animation already, and I re-import the model, the Animation Clip gets deleted and recreated, and the reference gets lost. I tried this modification, where it just checks if there's already a file exactly matching the path, and if so, loads and sets that value. I believe this all works fine, and preserves references to the Animation clip when used:

AnimationClip asset = AssetDatabase.LoadAssetAtPath<AnimationClip>(assetPath);

            if (asset == null)

            {

                // New

                Util.LogInfo("Writing New Asset: " + assetPath);

                AssetDatabase.CreateAsset(outputClip, assetPath);

            }

            else

            {

                Util.LogInfo("Updating Existing Asset: " + assetPath);

                outputClip.name = asset.name;

                EditorUtility.CopySerialized(outputClip, asset);

                AssetDatabase.SaveAssets();

            }

EDIT: It looks like under 1.5.1, the Prefab object (which gets saved to the Prefabs dir) gets recreated every time the import is run, which breaks references to it. Specifically, the FileID of the prefab changes, so things that reference the Prefab (such as the Slate sequencer) lose references. This appears to be due to a change in Importer.cs since 1.4.9:

// Unity 2023.1 crashes if saving a new instance over an existing prefab, so delete it first

bool assetExists = Util.AssetPathExists(prefabPath);

if (assetExists)

{

   AssetDatabase.DeleteAsset(prefabPath);

   AssetDatabase.Refresh();

}

I appreciate trying to avoid crashes, but the impact of the prefab getting deleted every time I update a character, and losing all references to it, is pretty catastrophic in a project. Maybe there's some other way to avoid the crash that doesn't delete the prefab? In any case, I'm on Unity 2021 LTS, and if I simply comment out that code the importer runs fine without crashing, and I don't lose prefab references.

A couple of things I noticed when updating from 1.4.9 to 1.5.1:

First, RL.cs contains the following statement, which doesn't compile:

using Codice.Client.Common;

Commenting it out fixes the issue (that library wasn't actually being used it seems), but I assume this will break things for people who can't easily edit the source.

Second, I tried out the new feature that imports animations from the _Motion.fbx. However, it seems like this only importing the Humanoid animation properties, but none of the Blendshapes. 

For example, if I export an FBX that contains both the Model and the animations, the importer will correctly create Animation Clips with all the blend shape values for all the model's SMRs. But if I export the FBX to put the animations into a _Motion.fbx file, the importer creates all of the correct Animation Clips, but the clips don't have any blend shapes in them.

Thanks for a really impressive tool, by the way. It's really made using CC4 in my project easier then I expected. 

Unity Auto-setup Release 1.5.2

Changelog:
1.5.2

• Animation Retargeter fixes.
• AnimationMode removed.
• Clip generation file name suffix corrected.
• Animation Clip overwrite no longer breaks references.
• Clip settings (foot IK, mirror, speed) reset to defaults on opening retarget window.
• Character prefab generation no longer breaks references. (Except 2023.1.1-5 due to Unity bugs)
• Rogue usings removed from code.
• Animation processing fixes.
• Correct character prefab used to retarget _motion.fbx files.
• Animation Clip overwrite no longer breaks references.

Seems to be a new "feature" that slipped past me, generating new guids when overwriting some assets. This helps a lot.



This particular Unity bug has been fixed in 2023.1.6, so only 2023.1.1 to 2023.1.5 will now recreate the prefab completely. Everything else overwrites safely now.

There were a few other bugs in the animation processing, see if the _motion files retarget all the blend shapes correctly now.
