Awesome! And I agree that full-res is the way to go; really you can only safely go lower if there's some roughness applied to the transmissive surface, or its geometry is complex. No good way to check for that. |

Description
Rather than completely removing transmission support in WebGL1, I think we can provide limited support by ignoring roughness (mipmapping).
I've also increased the
_transmissionRenderTargetresolution to 1x which fully solves issue 5 in #22009.
