I've been importing some of the preset shaders that come with the latest version for Iray into Shader Mixer and I was wondering if anyone knows anything about the brick called Users Parameters?
It seems to be in all of the shaders I've imported but each one has different options.
Also when I tried to insert it into a mdl network it said that it couldn't be used in that type of network despite having ALL as the description at the bottom.
Does anyone know any more?
