Exporting MH Combined Mesh

Development Character & Animation

Hey guys

For a clothing simulation on a metahuman, I am trying to export the combined mesh of a MH from Maya for import into UE. I will do the clothing simulation with Style3d Meta in Unreal. On two out of three metahumans it works great. But for one MH it always exports from Maya only the skeleton, without the combined mesh, see screenshot: On the left successful and on the right another MH with only the skeleton. I have tried all different FBX export settings (without animation, baked animation, constraints, different units, different orientations, …) up to a Maya reinstall.

Does anyone know the problem and can help me? I need the combined mesh for the clothing simulation.

Thank you so much!

Hey @brrrrapfiy

did you ever solve this? I am encountering the same problem. My combined mesh only exports as a skeleton.

In case anyone ever comes accross this problem, I solved it.
Here is the solution:

Step 1: Switch Maya to Rigging Workspace
Click Windows - Workspaces - Rigging

Node Editor at the bottom pops up

There should be 3 to 4 nodes in the node graph

Step 2: Disconnect and Reconnect Nodes
Disconnect f_tal_unw_combined_lod0_meshShapeOrig and connect it directly to f_tal_und_combined_lod0_mesh

Note: Naming might be different for your nodes, depending on the height and weight of your Metahuman

Step 3: Export as FBX
When you now export the combined mesh as FBX, it should not only be the skeleton but also the mesh :slight_smile:

I tried using a metahuman from with Maya 2024, I simply selected the combined_lod0_mesh along with the DHIbody:root and exported as fbx, it seems to work. I did have contraints, skeleton definitions, skins, and blendshapes enabled on export. If the fbx is imported into a new scene, it has linear deformations so it loses the rbf solver, but that doesn’t matter for my purposes.
