sceneview-android

If filament is compatible with OpenGL ES 2.0.

[pixelflinger]

filament has very basic support for ES2, in particular it only supports unlit materials.

Which device is it failing on specifically?

There is an error message similar to the following:

Are you using "feature level 0" materials? Again, filament has very limited support for GLES2.0, you must only use feature level 0 materials on these devices.

[zonda-alias]

Are you using "feature level 0" materials? Again, filament has very limited support for GLES2.0, you must only use feature level 0 materials on these devices.

Is the "feature level 0" here specific what be to point to?

Is there anything that can be used to check whether the model meets the criteria

"feature level" that is to say "Level Of Detail" ?

[pixelflinger]

no, feature level 0 cannot handle glTF. Again, we only have very limited support, and you will need special content for ES2.
