Export to Unity

The Unity recipe of the Process tab exports a Human Generator human from Blender as an FBX that Unity imports as a Humanoid character: a T-posed skeleton with the Humanoid bone names, the face as blend shapes, hair cards, and textures packed for the Standard and URP Lit shaders. The free Unity Companion sets everything up the moment Unity imports the file.

In Blender

1. Select the human, open the Process tab and choose the Unity recipe.
2. Set the Folder to a folder inside your project's Assets, so Unity imports the files straight away.
3. Press Export to FBX.

In Unity

Tested with Unity 6000.6 and Blender 5.1: the avatar maps all 55 Humanoid bones, every material gets its base color and normal map, and the blend shapes come through. By hand:

1. Import: with the folder inside Assets, Unity imports Jake.fbx and the Textures folder by itself.
2. Rig: select Jake.fbx, open the Rig tab of the Inspector, set Animation Type to Humanoid with Avatar Definition: Create From This Model, and press Apply. Unity maps the bones by name.
3. Materials: Unity creates a material per part and finds the textures next to the model. When it asks to mark the normal maps as Normal map, press Fix now. If a material has an empty Metallic slot, drop its _MetallicSmoothness texture in; the smoothness is read from the alpha channel. The materials inside the model are read-only; use Extract Materials on the Materials tab of the importer to edit them.
4. Hair: set the hair materials to Cutout (Built-in) or Alpha Clipping (URP, HDRP) and make them two-sided (Render Face: Both in URP and HDRP; the Built-in Standard shader has no two-sided option, so use a double-sided shader there). A Lit material shades the cards as flat surfaces; for highlights that run along the strands use a hair shader with the Jake_HairCards_Flow map, see Haircards › Hair shading.

Troubleshooting

• The skin looks dented, or a seam shows at the shoulders: the normal map direction. Unity reads OpenGL (Y+) normal maps; the recipe sets it, check it wasn't changed to DirectX.
• The hair is solid: the hair material needs alpha clipping, see above. Make sure the textures were exported as PNG, not JPEG.
• The scalp shows skin under the hair (URP): with Haircap set to As meshes, the haircap material is blended, which URP does not draw on a skinned mesh. Set Jake_Haircap and Jake_FaceHair to Alpha Clipping at 0.4; the Companion does this.
• The skin looks oiled or wet: the smoothness map at full strength with the reflectance of URP Lit. Lower Smoothness on Jake_Skin to about 0.7; the Companion does this and gives the skin its skin shader in URP.
• The eyes look like glass balls: the character was exported with the original eyes. Set the eyes to High or lower in Optimize Meshes.
• The eyes look matte, the pupil grey: the eyes have no smoothness map, so Unity gives them its default smoothness of 0.5. Set Smoothness on Jake_Eyes to 0.9; the Companion reads it from the .humgen3d.json file and gives the eyes its eye shader in URP, with the iris refracted behind the cornea.
• Arms are raised or lowered in every animation: the rest pose of the character and the animation differ. Animations made in the A-pose need the A-pose rest pose.

Frequently asked questions

How do I export a Human Generator character to Unity?

Select the human in Blender, choose the Unity recipe in the Process tab, set the folder to a folder inside your project's Assets and press Export to FBX. Unity imports the FBX and its textures; set the rig to Humanoid, or install the Companion package, which does that and the materials for you.

Which render pipelines are supported?

The Companion is tested with the Built-in render pipeline and URP; it sets up HDRP materials too, but those are not reviewed yet. Without the Companion the textures work with the Standard and URP Lit shaders as exported.

Does the character animate with Mecanim and Humanoid clips?

Yes. The skeleton maps to the Humanoid avatar by name, so any Humanoid animation retargets to it, and there is a root bone for root motion.
