Convinving Gabion Walls?

[Dave Buckley]

Anyone have any good techniques for a convincing gabion wall?

 

I've made some custom maps. but they just aren't cutting it for me.

 

Someone must have had to do this previously?

I read a thread recently (Chaos group forum maybe?) where people were discussing using various fracture/voronoi scripts to do the rocks.

cheers, steph, I think a map will suffice, the wall isn't a focal point and will not be that close to the camera, I'm just struggling to make the maps/material look convincing.

 

I have the stone map, and have simply created a grid over it and essentially rippled the grid to give the wire look. Looks ok in Photoshop but the render looks poor, so it's possibly the way I have the material setup.

 

Gonna have a play with vray blend and masks me thinks

Might work better if you have two boxes nested inside one another. One with the stone material and the other with the wire grid.

[Dave Buckley]

the two boxes works nicely,

 

just increased segments, latticed and some noise gives a nice gabion basket look

I was just reading through the thread and as going to suggest the same thing (two boxes - one rocks, one wire) - I've used this technique before and it worked out great.

 

If you UVW map all the rocks in a larger set you'll help to remove repetition too.

Would like to see the result of this if you can post it up?

You can use Rayfire to make realistic breakings or some dynamics (reactor or physx) to stack rocks as the shape you want. Good luck
