Diffusion Filter for MikuMikuEffect

Created by: Soboro


You can control the intensity of the effect by adjusting the Tr (Transparency) parameter,
and control the blur radius using the Si (Size) parameter.

The default settings are a bit strong, so please adjust them as needed.

You can perform simple color correction by adjusting the position of the accessory.
The X, Y, and Z coordinates correspond to the R, G, and B color channels, respectively;
adjusting these values ??within the range of -1.0 to 1.0 alters the intensity of each color channel.


Other adjustment parameters have been grouped together at the beginning of the effect file,
so please modify them as appropriate.
As of Ver. 7, you can now configure the blending mode in greater detail.


 Update History

Ver. 7
E Completely rewritten. Reduced the number of rendering passes.
E Reintroduced the simple color correction feature in a revised form.

Ver. 3

and control of the blur radius via the Si (Size) parameter.
