Geoset animations are generated by animating the render visibility of an object (see below) or by changing or animating its object color, which translates into vertex colors (vertex colors are treated as a global tint for the geoset). You can also add vertex colors to a material by adding an RGB input node anywhere in the node graph and naming it "VertexColor". This is convenient when have many small objects with the same material which should share tint.

You can also animate an object's visibility by keyframing the "render visibility" property (you can do this by holding your mouse over the render icon in the outliner and pressing the I key) - optionally, you can create a custom property called "visibility" and animate that. Using the Color field of an object, you can animate its tint value (setting the value to anything else but white will also create a static color GeosetAnim for it).

A material consists of multiple material layers, which will be rendered from top to bottom, and blended together using the specified filter mode. Some filter modes support an additional alpha multiplier, which can be animated. To add a texture animation, create a mapping node in the node graph with the same name as your layer, and animate its properties.
