on the topic of immage format:
i like the way brigade e5 and 7.62 high caliber approached the weapon inventory image. instead of a static image they generated the image from the 3d model taking all the attachments into account.

this to me is the most efficient way of doing it since there is no need to create an image after creating the weapon model. so this should somewhat streamline the art creation process. and also make it easier for the fans to generate content.
