How I recreate/model a cave that looks exactly like this (?):
I have tried using particle systems but it ended up looking ugly as the particles overlapped way too much and could not be given an individual, unique offset as seen in the image.Am I missing something regarding the particles?
Also, I'm open to any other suggestion to go about this.
Since the question was on particles here's my take on it.
Start with a cylinder.
Subdivide it a number of times but make it somehow irregular with a fractal:
Then create some cuboid object (I put it on a different layer so that is out of the way...)
Then on the cylinder create a particle system.
Make the start and end frame 1 (so that all of particles are present on frame 1)
Use the cuboid object as the render object.
For rotation select the axis that makes sense depending on how your object is placed (in this case, the object X axis works for me), and set the random rotation to Zero.
Then give the render object some variation on size.
Optionally you can disable the emitter so that only the cuboids show on the render and not the original cylinder.
Giving the particles a bit of randomness might make them more interesting.
You could achieve an approximate result through a Remesh modifier.
Add cylinder object, rotate and scale it to make it elongated and subdivide accordingly. Erase the end faces.
On top of it add a Subdivision Surface modifier set to Simple, then a Displace modifier.
Set the displace amount to a high value like 1 (depending on the size of your object) and add a new texture.
Switch texture type to Musgrave or similar and increase the size so the deformation forms big lumps (as opposed to small frequency noise).
Now add a Remesh modifier to the object set to Blocks. Adjust the Octree Depth to a high enough value to generate desired sized blocks.
You can now add another Subdivision Surface modifier set to Simple on top of it followed by another Displace with a new Musgrave texture.
Seth both the Displace Distance value and Texture Size to small values to generate small distortions. Adjust accordingly
Start with a circle, make faces. Extrude and then S to make the section closest to you wider.
Delete faces from both ends. Then add round loop cuts (Ctrl+R) to the inside of the object. Next, grab faces and extrude inward inside the object.
Start with the bigger pieces extruding a few faces at a time. Use R and S on the extruded faces to add complexity.
Add vertices and other loop cuts until you get the desired results.
