Irregular Stone Wall
« on: October 26, 2021, 07:45:57 PM »
Hi everyone, If I wanted to build this wall, which has irregular stones, no plaster in between, and a non-uniform height, how would you do it? Using forest pro? using railclone?
Any pointers would ve very helpful!

Thanks a lot

Hi, thanks for the question. Here's the reply from a similar question that was asked before, I hope it helps:

How you tackle this depends to a certain extent on the type of dry stone wall construction. If the wall has visible courses where the jigsawing together of stones is clearly visible then the easiest way is to use a similar approach as shown in this RailClone thread, and here's another with a similar approach. This method involves creating pre-composed scatter objects that interlock to help hide obvious joins.



You would then pick the Full distribution map and adjust the X and Y Density separately until the scattered objects fit together. You can use this technique with surface in either XY or UV mode. I've included a file called drystone_tetris_style.max to illustrate these techniques. You can download it from here.



Alternatively you may more of a "pile-of-stones" style of drystone wall in which case you can use XY or Surface mode to scatter simple rock models onto a surface. In this technique you would simply scatter using a Full distribution map (as in the previous example) onto a vertical surface using surface > UV mode, making sure that the Direction Slider is set to 0. To get more variety out of the stones I'd randomise rotation between 0 and 359 degrees for all 3 axis.



You can download a sample file for this here. Of course the advantage of using Forest Pack for this is that you can use Forest Color to add additional texture and tint variation, if you need any more information about this we recommend the Autumn Park tutorial.

I hope that helps but if you have any further questions please don't hesitate to let me know.

Many thanks!

Perhaps a classical displace (V-ray displace) is better for this purpose.

Hi Paull I think that the method you shared here would work best for me:
https://forum.itoosoft.com/railclone-pro-(*)/is-this-possiblefeasable-with-rc-pro/msg11189/#msg11189

But how would I make it so the wall doesn't have the same height all around? I need it to follow the surface attached.

I tried the second method you mention, using rock models on a surface with Forest Pack but the problem is that you get lots of holes and intersections that are really noticable

Thanks a lot!
