Is carve bad to use in any situation? If I had a hexagon shape and I wanted to cut a hexagon out the middle, is it ok to do this using carve? Same as if I had a long path and wanted to cut an indent out of it, is that okay?

I understand carve shouldn’t be used to carve out connections between buildings etc where the map may leak, but what about detail?

Carve usually creates unecessary and Hammer-breaking microbrushes and compiling errors, use the Vertex manipulation tool instead to move the vertices of several brushes in place to form a hexagon with a hole in it.

Ok thanks I’ll do that :slight_smile:

So to create a hexagon, is it okay to use clipping tool. It will leave multiple blocks that could be one, but does that matter? Or do you end up with the same effect as carve?

EG: Like this:

Clipping tool is fine as long as you’re slicing convex shapes. (don’t make concave geometry).

A quick example I threw together, using the Vertex Manipulation tool push those highlighted vertices on the first image. Push them away from the opening.[/thumb]

Also I would turn brushes 1+2+3+4 into a func_detail (CTRL+T).
Always func detail brushes used for decoration as opposed to blocking visibility, it will save you from nightmarish compile times.


That’s a lot of geometry, you’re wasting a lot of brushes on such a simple shape. Try laying them out like this:


Carve is okay as long as you only use it in simple situations such as splitting brushes or shaving off a corner to make a ramp.
Do not try to make any kind of complex geometry with it, the result will be DISASTROUS.

Also this.

So this example is using carve? But just using it effectively rather then wasting brushes?

This is my cuts so far - I used the clipping tool to make lots of cuts, they re-did those cuts once I had the basic shape to make it neater…

That’d be vertex manipulation right there, you’d move the brush’s corners until they create the shape you’re looking for:[/thumb] [thumb]

(From Interlopers, simple example…)

Edit: Hell, Even the Arch tool is more brush-efficient than cutting them up:

What is up with your brushes there?
Look just upload a copy, ill fix it for you.

Right, I think I understand what you’re saying. So you create rectangles and move the corners so they match up with the others as in your first example?

As far as I can tell, there’s nothing majorly wrong with it except that I’ve got an extra brush at each corner, that could be made into a single split.

Delete the corner brushes and use vertex tool to edit the brushes into the right shape.

Thanks a lot :slight_smile: I’ll do that.
