Hi,
We tried importing gltf and datasmith files in 5.3.2 engine version at runtime in packaged build. With gltf, the geometry is imported properly and if we set it to combine the meshes upon importing, then all of the materials show up properly. However, if we set it to not combine meshes (for example in case of a house with many parts), then some materials are imported properly, some are not. Also, if we import them async, materials are lost.
In case of datasmith, we are experiencing crashes or lost materials, even in the editor. Please note that this exact same datasmith file is imported perfectly in twinmotion. Do you guys know about these issues and are there fixes on the way for 5.4 version regarding these…?
