@MartnD Apologies for the confusion. To clarify, when I referred to the “old exporter”, I meant generating the meshes in Unity with our now-obsolete Depthkit Studio Mesh Sequence Export package (part of the Phase 8 release). The new mesh exporter is the Textured Geometry Export option built directly into the Depthkit app, removing the need to use Unity at all to produce textured geometry sequences, and the newer Phase 9 release of the Depthkit Expansion Packages for Unity no longer includes a Mesh Export package.
The Depthkit Studio Mesh Sequence Export package for Unity is only meant to be used with the other Phase 8 packages and image sequences generated by Depthkit v0.6.2 or earlier, and because it is no longer supported, has not been tested with image sequences produced by Depthkit v0.7.0. Although you’re welcome to continue testing yourself, we can’t provide direct support for this workflow, and instead recommend migrating a copy of your projects to v0.7.0 and use that mesh exporter instead.
We’ll continue troubleshooting your issue with the new exporter in this thread.
