Screen Filters (Effects) - emd4600/SporeModder-FX GitHub Wiki

This is a list of all filters that can be used in the filterChain block of a screen effect. Multiple filters can be combined to create a post-processing screen filter.

In this documentation we refer to a special type, buffer. A buffer is a temporary texture used in screen filters; all filters take two arguments: the source buffer where the information is taken from, and the destination buffer where the result of applying the filter will be written.

When a buffer type is required, these values are possible:

• The name of a temporary buffer that has been declared in the filter chain with texture. For more info, check the Screen Effects page.

• particlesX, where X is a number. For example, particles0

• For the source buffer and any buffers used in filter options (as they are sources as well), source. This is the base image where the screen effect is being applied; that is, what would be displayed on the screen without post-processing.

• For the source buffer, the resourceID of a texture.

• For the destination buffer, dest. This is the final buffer that will be displayed on the screen.

• For the destination buffer, an integer number, 0, 1, etc. This is untested, but it is probably the render target index.

An example:

filterChain
    texture temp0 -size 512
    # Blur a source texture and save it on temp0
    blur1d textures!test_texture temp0 -scale 2.5
    # Add the blurred texture into the screen and display it
    add source dest -texture temp0
end

Used to apply a custom shader. The -samplerX properties will be textures passed to the shader; the customParamsX will be custom parameters that can be retrieved in the shader with the customParams shader data variable.
