Pocket Infinity seems to have a glitch with aiming down sights There seem to be two types of ADS rendering modes, 'iron sights', and 'scopes' With iron sights, the weapon model is directly rendered With scopes, a multipass render overlay removes any polygons behind the scope glass I'm sure your programmers have their own terminology for this, but my description should be identifiable to them Pocket infinity has an iron sight, but its render mode is set for 'scope' This causes portions of the model to dissapear when ADS Note the distinctive 'walls' on each side of the red glass
