I've been working on an underwater scene for a project and now reached a standstill due to an issue that I encountered. I'm trying to render a scene such as the ones in the images below, I tried using the different volume shaders available on blender but can't figure out the best combination to achieve such a look. The god ray (kinda) lights along with the depth fall off is what I aim to achieve.

best, AJ

You could try these technics:

Create a cube that contains your scene, give it a material with the following setup: Plug a Noise Texture, 2D mode, into a ColorRamp that you plug into the Density of the Volume Scatter, tweak a bit the rotation values of the Mapping node. It will fake the ray lights. Put a Sun above the cube. To make it more interesting you could mix the ColorRamp with another Noise (in 3D this time):

Or create a classical Volume Scatter setup and put several Spot lights to create the rays:

To create a gradient on Z, mix your setup with a Separate XYZ through a Color > MixRGB in Multiply mode:

  • $\begingroup$ Hey! Thanks for the reply, I'll try to do that. Do you think adding a light path node would help get the same results? $\endgroup$
