Btw.: Comments are welcome in both threads (entries/voting). Have fun! :slight_smile:


Hi I just finished my render and its completely pure but I’m not non-competing this round just thought of a cool idea.


That is lovely

Water Cave Fish Tank

Non-competing (Open)

Cycles, 256 samples, particle system, Graswald ($), CEB Stable Diffusion for the coral background image, catfish and anchor models from my cnc pattern library, chest from another aquarium scene

The little catfish really enjoys his water cave where he can sleep at night when the lights are finally turned off.


Nice, i know a real bevel would make some issue, maybe a shader bevel would look nice. :slight_smile:

Sounds like a great idea. In order to save some resources, a mix of both solutions might also work just fine. A Bevel-Modifier could be used on the foreground columns while a shader could take care of the background.

Hi! It is first challenge for me and English not my first language. So, I am not sure about understanding challenge rules. But I must to try :slight_smile:

‘Lurking in the Shadows’

Pure, Cycles, 1024 samples, Used 1 rock texture.



“Snuck into G.wise’s Cave”
Inspired me with all that geometry.
I snuck a camera crew into your caves.
Love your render, great job!


GLUB SUBWAYS (Great Leaky Undercity Bore Submerged Under Both Water And Yack Street)

Pure, Blender 3.5, Cycles 16000 samples, 100% procedural

A 100% Geometry Nodes scene. The only objects in the scene are: Camera, Light, Light.001, BezierCurve(to dictate tunnel route). Here’s my nodetree (which has several subtrees that I developed earlier, but none of them produce visible geometry). All materials and compositing are procedural.

It’s a subway car being chased by water flooding into the tunnel, which the storm grates (brown, on the bottom of the tunnel) are doing nothing to stop. At least the lights still work (for now). I wanted to add some fish and a mouse, but I couldn’t figure out how to do that in GN (and I ran out of time). In the meantime, litter flows with the water and sits on the tunnel floor. Minus the water and subway car, I now have a reusable subway generator that only needs a curve to tell the path.

(not the entry)

Too bad #nodevember is over. :slight_smile:


Oi so you were that weird camera man I thought it was weird that some won wood jump into the water with a 10K camera, but didn’t say anythinggrinning:
Love it looks greet did you use geometry nodes for the pillars?

Haha! Don’t mind the camera crew hanging out under the water.
No nodes, was, super lazy, a plain old particle system

Nice, good idea

My goal was to create an illustration in a style reminiscent of Chesley Bonestell, (1888 to 1986), who’s art depicted space flight and the exploration of distant planets. His work appeared long before the advent of space exploration as we know it today. I hope you enjoy my rendition of “water tunnel”.

Modeled in Blender 3.5.1 and rendered in Cycles. Pure. 1 rock PBR texture and 1 ground PBR texture used.
