View Full Version : physics boulders?

Is ther a way to add noise to a brush without displacementing it? For a kind of boulder looking brush.
I am attempting to make a kind of landslide where boulders and other debris will block out the path.

You could make spherical brushes and turn them into func_physboxes. From there you could manipulate the verticies to make them look natural.

you couldn't d that using vetice manipulation. becuase you have to keep a single normal per plave you have to keep at least two edges perpendicuar. long story short you couldn't raise manipulate an edge on a brush and then nmanipulate perpendicular edges on any other brush that is in a stright row or column with that rush. I'd say you want to do some simple modelling.

yeah modeling probably the best bet, especially as dynamic brushes have poor support for lighting.
But you can "fake" a displacement boulder thusly:
Create a spike brush that has a triangle for a base, so that all faces have 3 edges, 3 vertices.
This way it will be impossible to create coplanar faces. Copy that wedge a pile of times around in a spherical arrangement and snap the vertices together. Now you can fashion your bumpy boulder by selecting intersecting vertices, and tie the whole thing to func_physbox

yeah thats the way. I'd be happy to fashion you one and sen it to you as a prefab if u pm me your email :)
EDIT: scratch that. I've never been able to make an invalid triangle brush until I tried this. Don't know how it happened but I got a strange error.

wow what was the error?
