RPG Architect supports both sprites and 3D models in the engine. Both support a hue-shift to adjust the overall color.
Sprites Sprites support multiple Image formats. They can be displayed as Billboards, Flat X/Y/Z Planes, Cardinal Crosses, or Complex Cardinal shapes. They are capable of having a translation (in pixels) applied to them, as well as a scale (the Z scale is ignored for Billboards). They have Sprite Format parameters that can be configured as well, such as number of frames, frame duration, and facing directions (if applicable).
Models Models support 3D model formats. In addition, they can utilize pre-built animations that are baked into the model. Models support the use of scale, translation, and rotation.
