No Horizon Occlusion slider when selecting GGX in Reflections

G-Saviour18

Hi all,

I'm hoping someone knows why I am missing this Horizon Occlusion slider whenever I choose to use GGX in reflections in Toolbag 4?

My old copy of Toolbag 3 still has the Horizon Occlusion slider as shown below:

The slider is just not there in Toolbag 4, I believe it should be there as everyone else seems to have it still from what I can tell, thanks for any help! :)

This setting is no longer supported in Toolbag 4.

Hi Joe, thanks for answering, in that case is there an alternative/ or other settings used to dealing with reflection for a skin shader since GGX is no longer supported?

I can see that when GGX is added to the shader it does still have an effect on the skin, which for now looks better than having it off

Sorry if there was some confusion, GGX is still supported, however, the Horizon Occlusion setting is no longer supported - this was an outdated technique that is no longer applicable with the latest changes to the renderer and material system.

To control reflections, you'll want to work with the Reflectivity panel. For skin I generally find the Specular model to be more flexible than the Metalness model, as you can control reflectivity and fresnel directly. The Advanced Metalness model may be appropriate too, especially if you're trying to match the Unreal engine.
