Properties

Effect file

Set effect file path. The effect file will be directly sent to OBS Studio using gs_effect_create. You can choose from bundled examples or can modify it by yourself.

Do not use cache

If unchecked, the effect file will be read one time. If another source try to read the same file, cache will be used. If checked, the cache is disabled. This will be useful to reload the effect file when you debug the effect file.

Number of sources

Set number of sources sent to the effect file. Some effect files in the example only support 2 for this property.

Source i

Select the source that goes to the effect file.
