Liquid Shader Work (for Unity Build-in Pipeline)

We have been working on a 3D adventure game and require a Unity tech artist with skills in shaders.

Brief:
- We require creation of 2 liquid shaders + appropriate art for our game Dros.
The style is to match the existing game which is a stylised PBR pipeline.

The solution is to be done in Unity using the build-in pipeline.

We require 2 main looks. One for a sewer-themed area, the other a lava-themed area.
For both areas we require some specific solutions:
1. A general tiling look for open areas (1st priority)
2. A flowing version for rivers/channels that can also double as ‘waterfalls’

We require the solutions to still be optimized for the Switch version.

1. For the sludge look: Mario Odyssey Lost Kingdom purple sludge
