I’d like to be able to split the BSP brushes (not static meshes), for example to cut one surface of a cube in half.
Is this possible in UE4?
The “Brush Clip” tool (with split tickbox) sounds promising, but when clicking Apply I get the following message:
“Modifier (Brush Clip) : You haven’t placed enough clip markers to perform this operation.”
I can’t find any mention of clip markers in the documentation, on Google, or in the editor itself. Is this feature currently supported?
Hi uunx,
You can go into “Geometry Editing Mode” and then you will see the “Split” option. You can then select an edge of a BSP and click “Split” to do exactly what you have described. Let me know if you have any questions.
Here is a little more info: Geometry Brush Actors in Unreal Engine | Unreal Engine 5.1 Documentation
Ah, interesting, I didn’t realise edges were selectable.
However, this seems to only split brushes in half. Is there any method of choosing where the split should be? For example, in Hammer (for source engine games) you can draw a line to choose where the split should happen before committing the split.
(I realise in my example I said to split a brush in half, but I was hoping for a more solution allowing it to be cut anywhere)
Unfortunately, the Split is limited to just the halfway point. There are some requests in our database to expand on the functions of BSP tools, but it may take a while to have those implemented. I apologize for any inconvenience this has caused you.
I hope by this time you already have found the answer for your question. If not, then you can cut BSP anywhere you want, using Brush Clip Tool with Split checked.
Note that Clip Tool works only in orthographic view (top view or any other side views).
To place clip markers use Space key.
