7.1.14.15830455952 - Second Life Project glTF Mesh Import

Release Notes

glTF Mesh Import Alpha

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.

Known Issues

• Joint overrides may not work for all meshes.
• Some Meshes will not upload with materials
  • This is a technical constraint due to how glTF materials work.

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.
• Sub-meshes may not have more than 65,535 vertices
  • Sub-meshes that have more than this limit will be split into more meshes.
• You may not have more than four joint weights per vertex on rigged meshes
• Rigged meshes must be rigged in accordance with with one of the Second Life skeletons, which may be found at https://github.com/secondlife/creator-resources

These constraints will not be changing with this first release of glTF mesh upload.
