Hey i just downloaded this, and i have some questions.
It seems to be missing some texture? There are references to some "height.jpg" that isnt included (or at least i couldnt find it). Is this something necessary or maybe some leftover reference to an older version? It's in the v2.0.1 documentation's "Required Texture Assets" table
The other three new textures dont seem to actually be wired into the updated v2 shader either. "water 0340.jpg", "water 0340normal.jpg", and "water normal 2.jpg" are all present in the download, but "Shaders/water shader 2.gdshader" has no sampler2D uniforms for "water_normal_1", "water_normal_2", "surface_noise", or "height_map" at all.
These texture uniforms arent declared, so nothing in the shader samples the textures. The surface normal is still generated the same procedural way as v1.0. So the "texture-based normal map pipeline" described as the headline new feature in the v2.0.1 docs isn't actually in the shipped shader code since the textures are just sitting in the folder unused.
