How can I make my water not look like ink? I'm working on a small creek including animated water (using a fluid domain). While I'm satisfied with the baked flowing animation of the water, I don't really like how it looks. Here's a render:



It's way too opaque (nontransparent), I would like to have a more cristal-clear type of water. I've cranked up the brightness of the sun, but as you see, that only increases the brightness of the reflection. I've tried using fill lights from different angles to brighten up the scene, which works to some extent, but the texture still looks like ink. So I'm looking for help on how to make it look more like clear water.

Here's my current texture:
Maybe im just too late right here, but anyways.

You need to mix a glass shader (put 1.35 IOR) with a transparent BSDF and you're done, or if you wanna go beyond and have a photorealistic water looking, you can do it by combining the Principled BSDF and transparent BSDF.

Change these settings on the Principled Shader:

Roughness to 0 or 0.05 (depending on the type of water, if dirty, clean, etc)
IOR to 1.35
Transparent to 1 or 0.9 if dirty and such (you can also play with the colour and the transparent bar to add some color to the water)
