If you choose to override the entireĮffect, be sure to define these as uniform variables and use them where necessary. The plugin automatically populates a few parameters which your shader can use. OBS log file, which you can view with the Help -> Log Files menu in OBS. In many cases the output of the effect parser will be written to the Simply see your source render nothing at all.

Or other parts of the effect for some reason, you can check the 'Use Effect File (.effect)' option.Īny parameters you add to your shader (defined as uniform variables) will be detected by the plugin and exposed If you wish to customize the vertex shader Standard template to add a basic vertex shader and other boilerplate. Normally, all that's required for OBS purposes is a pixel shader, so the plugin will wrap your shader text with a That need to render outside the bounds of the original source. The option is provided to render extra pixels on each side of the source. This can also be used to reload an external file if changes have been made. Note that you will need to use the 'Reload effect' button to apply your changes. If you are entering your shader text directly, To changeīetween the two modes, use the 'Load shader text from file' toggle. Shaders can either be entered directly in a text box in the filter properties, or loaded from a file. The filter can be added to any source through the 'Filters' option when right-clicking on a source.
