here is #softstacking Rules

Soft stacking allows for a more nuanced blending of layers, where a layer can be partially in front of and partially behind another layer within the same pixel. This creates a more realistic and fluid visual appearance.

Sub-pixel Complexity:

The key to soft stacking lies in representing sub-pixel stacking information. This involves using stacking coefficients, which are akin to continuous alpha transparency, to determine how much of each layer contributes to the final color of a pixel.

Practical Applications:

Soft stacking can be used to create effects like fog, smoke, or other translucent materials where objects appear to blend and interact realistically. It can also be used to add subtle depth and realism to images or animations. @softst

Examples:

Imagine a scene with layers of fog. In traditional stacking, the fog would either be fully visible or completely transparent at any given pixel. Soft stacking allows for the fog to subtly transition from being in front of an object to behind it within the same pixel, creating a more realistic sense of depth.
