Hi, I cannot find a way to prevent painting a given foliage type over another foliage type (using the paint tool, not procedural). Is there a way to control this? Thanks.
There should be a tick box in the foliage tool for the types of objects the foliage will âpaintâ onto - static meshes, BSP meshes, etc. One of these should be for foliage, and unchecking it should do exactly what you are after.
I tried that but that doesnât seem to work (4.17.1): I tested with a rock and tree, both having the foliage filter unchecked. I populated an area densely with the rocks, then I populated trees over the rocks andâŚI had trees populated over the rocks. I would have expected the trees would not pop up. In case that would help I made the rocks as âblock allâ collision but this had no effect on the fact I could still populate trees on top of them.
Oh, I see what you are trying to do.
The tick box stops foliage from sitting directly on the surface of other foliage (so grass doesnât appear on the tops of trees, for instance). Your trees shouldnât be sitting on the top of the rocks - they should be sitting on the ground. However, I donât think there is any way to tell the foliage tool that âtrees arenât allowed on ground already covered in rocksâ.
after painting, use the SELECT to move the foliage ⌠top right, little arrow icon.
Indeed there doesnât seem to be such a functionality for painting foliage (too bad!), however this exists withing the context of procedural foliage spawning. In such a case, if spawning trees in areas where there are already rocks, the rocks instances below the trees will be deleted. It would be great to have the same functionality for foliage painting, this would limit overdraw.
