My life is running at 55.6 ms of frame time which is roughly at 18 FPS. I think

Baking AO in Blender using the AO option takes longer time. I found out using the AO node in the shader is much faster and also allows "only local" option. In fact the node output can also be lerped, there's more control via this way than using the bake AO option.

Even the inverted value of AO can be adjusted to make cavity map.

I forgot I have this saved in bookmark. Matcap collection. I've been using some of it for a long while. There are like probably 641 different matcaps available there
