Я пытаюсь загрузить файл .obj из блендера в Java3D, но всегда возникает ошибка:
com.sun.j3d.utils.image.ImageException: javax.imageio.IIOException: Не удается получить вводпоток из URL!
Самое странное из всего этого - то, что когда я загружаю модель из Интернета, все в порядке, но когда я импортирую тот же файл в Blender, а затем экспортирую его (без каких-либо изменений), он не работает.
