Static Texture 3D is a component that represents a bunch of textures stacked on top of each other to make a 3D grid of pixel values. These textures can be displayed in 3D, or sampled via 3D positions in a few different components or in ProtoFlux Nodes.
This is commonly constructed via 2D slices which are Static Texture 2Ds. These slices represent XY planes of incremental Z coordinates ranging from 0 to 1. This can either be packed into a single 2D image, or imported as multiple 2D images in a folder where each slice is alphabetically organized.
Currently the maximum packed 2D image that the importer detects as a valid 3D texture is 1024x32. In this orientation there are 32 total cells arranged as 32x32 pixel sub images.
Linear 3D Texture
The X or Red channel increases constantly from 0 to 1 from left to right within each cell and repeats.
Linear 3D Texture Red channel
The Y or Green channel linearly increases from the top to bottom.
Linear 3D Texture Green channel
The Z or Blue channel increases step wise within each cell itself, the first cell being all 0, and the last cell is all 1.
