Water SSR is including UI elements in Flat

Flat, notice the darker area in the red area. The bottom of the dark area is a straight horizontal line. Best done at coc guardianstones and moving the UI up and down.

For VR see 3 in #193 (comment)

it's not UI. it's a bug with the alpha channel of the ssr texture. when we replace the ssr it will be fixed.

limbs can be masked by using the stencil texture i think?

Turns out the limb was dynamic cubemaps and I stenciled it.
