Sceneform generates sfb files without colors
问题 I have problem with the objects generated from Google Sceneform Tools (Beta) v1.13.0 in Android Studio. I downloaded the object ( .obj file ) from poly and imported to Blender to change the dimensions. After that exported again as .obj file . When I use it to generate .sfb file in Android Studio with Sceneform tools, the .sfb object that is generated is only black. Left is object ( .obj and .mtl ) imported in Blender , and right is generated .sfb file in AndroidStudio. Thanks in advance.
