• Export your environment in Fbx. (Separate the mesh you want to set as collider, so that it’s no more than a few hundred polygons for rel-time performances.) You ideally want a special version of your environment mesh, with just the surface needed for collision, and with very smooth edges, so that the charatcter’s root doesn’t snap, but elevates smoothly when walking over that volume. You can use remesh modifier (Voxel) in blender to quickly make this collider mesh:

• Import in your mocap fusion Unity project, that has APS_SDK (unity 2019, see: Here )

• Add collision script to your low poly mesh, or add collision cubes. NOT convex, and just pick your mesh at the bottom of this mesh collider component.

• Save your scene (set proper name to identify it) → Publish the scene as new Mocap Fusion environment. (you can add the VR player to define your spawn point)

• The two button for folder at the bottom, are where you can copy paste your new Scene asset from this Unity project, to your Mocap fusion assets. Just copy paste from the first folder to the second, the “.scene” file that was created, that has the same name as your unity scene file.

• In Mocap Fusion, you will see your new environment (with physics colliders) in the top left tab: Addons > Scenes.

• Activate this Feet collision button:

• After enabling the toggle you should see the foot collider mesh show briefly (you can set visibility to display permanently from the avatar profile options).

  

• Then you will want to tweak the feet physics settings, in the top bar, Profile Tab:

  (missing screenshot for feet force etc.. to reduce jitter, adjust size etc..)

Showcases:

• A few collision cubes matching a high-resolution debris scan. Some cleanup in blender with IK feet. By Liok:

  

• Feet physics needs to be tweaked on your avatar, in Profile Tab, to avoid this kind of physics jiggle on them: (that can still be cleaned-up easily in post-animation with IK.)
