Hey everyone! Welcome to a new alpha for content creators!
We are very excited to begin offering a new mesh upload option, following the glTF mesh standard. Now content creators may explore the endless possibilities of importing glTF models with .gltf and .glb file types.
This is an early Alpha release and we have done our best to smooth out the rough edges and already resolved many bugs and crashes. While we know there are more to be found, we feel this is ready to start receiving general feedback from the community.
Generally, this should have similar constraints to COLLADA upload, with some key limitations:
We cannot currently detect the up direction that’s been exported from another application. Please always export with “Up” being Y+
In blender there is an option in their glTF exporter to ensure Y+ is up.
We currently do not support a unified material upload solution in the mesh importer. This is coming in a later release.
Known Issues
Sub-meshes with more than 8 materials will fail to upload
Joint overrides do not presently work
Meshes will not upload with textures
This is a technical constraint due to how glTF materials work.
During the Upload > Model process, before any L$ are spent, GLTF models compressed with Draco (KHR_draco_mesh_compression) will not upload.
Existing Mesh Constraints
As a reiteration of our existing mesh constraints:
Sub-meshes may not have more than 8 materials
Sub-meshes with more than 8 materials will be split into more meshes prior to release in a future build
Sub-meshes may not have more than 65,535 vertices
You may not have more than four joint weights per vertex on rigged meshes
