I have a serious issue with curved brushes Created 4 years ago2020-08-05 19:49:34 UTC by SirCobalt

So I have this road in a map I'm making. The road is supposed to turn right but not at a 90 degree angle. However, I am completely clueless as to how to make a curved road without the result looking absurdly thin. I've also been trying to do the same with tracks and hollow circular objects but I run into the same problem.

You can do it with vertex manipulation. Check out 1 minute in in this video. Apologies if it's too fast, if it is, you should look into the vertex manipulation tool.

I appreciate the help, but unfortunately my problem still persists.

How can I put a screenshot on here?

There are various tools that you can use:

• Shearing is quick and easy, but significant shearing results in 'thin' brushes.
• With the clipping tool (shift+X) you can start with a larger brush and cut away parts until you get the desired shape. Press shift+X again to cycle between modes (remove right side, remove left side, keep both sides).
• With vertex manipulation (shift+V) you can move each vertex or edge individually, create new edges (by selecting two vertices or two edges on the same face and pressing ctrl+F) and remove vertices (by dragging them onto other vertices). This is a powerful tool, but keep in mind that each face must remain perfectly flat - bent or curved faces are invalid. Brushes must also remain convex (e.g. no U-shaped brushes). Press shift+V again to cycle between modes (vertices and edges, vertices only, edges only).
• When creating a brush, you can choose between a few different shapes. 'block' is the default choice, but 'arch' is probably more useful in this case. Keep in mind that it'll be facing towards you in the 2D view that you most recently clicked on.

If 'hollow circular object' means you want to create a curved pipe, those can be tricky and time-consuming to do by hand, depending on how many segments you want. I usually stick to 1 or 2 segments, with 1:1 and 1:2 shearing. I also keep vertices in the straight parts on a 2-unit grid, so 1:2 shearing and clipping won't produce invalid brushes. There are also a few tools out there to generate curved shapes, but I'm not sure if they can do hollow pipes.

I don't think I'm familiar with shearing.

With the selection tool enabled, clicking inside a selection box in any of the 2D views will cycle between resize, rotate and shear mode.

Using the block tool, create an arch in a square area. The arch should have a wall width of half of the width of the road you will create. The arc should be 90 degrees. Number of sides should be whatever you want. This creates a perfectly on grid 90 degree arch. You can delete half the parts of it to create a 45 degrees road etc.
