Broken walls

Elodin · Feb 2015

Hello everyone,

Any ideas how to properly create those? Destroyed walls?

I was thinking of using decal, like on one of the tutorials here, but this looks much more complex with it's own geometry.

Hmm, I'm curious too.

A fast, cheap but not very quality solution would be to create several brick models and a straight edged wall, then just repeatedly place the brick models on the edge to cover it. For example in Dark Souls it's done that way for example:

Do they break in real time or are they already broken? If it's a key piece I'd say just model it and set up part of your tiling texture to be the broken edges, otherwise I like the technique that syncing suggested.

There are two texture in play here. A tiling brick for the face and another tiling rubble damage that follows around, it blends with an alpha mask so you don't notice any seams.

Butthair,

It's not just the texture. It's the whole geometry of bricks.

Yes, it has 2 textures. One for a regular wall, one for broken geometry. It's not just alpha or a plane with masked damage.

I provided multiple links that go over this topic with different implementations.

At the simplest level, 2 textures with alpha blend achieves the idea. Once the basics are understood, getting fancy with geometry is the next step.

So you're suggesting making tileable broken brick mesh? And then put it around the walls?
