- Opening your model in your preferred 3D modelling tool and check that your model is in the correct position.
- Adjusting the scale of your model within the framework. Models sizes on screen are determined by the world they are added to. E.g. If you have a cube of height, width and depth of 10 and its added to a marker of height and width 10 it should take up the whole marker. If you add your model to a marker that is fairly large your model could be smaller than anticipated and vice versa.
- Check your marker is being detected or you have started markerless tracking and the models been adde to your trackable/markerless world.
