I would love to be able to have a section of a terrain ‘voxelized’ or at least capable of having a hole so that I may attach another object where it is. This would make it much easier to create caves, overpasses etc… in a terrain. Without having to resort to workarounds, Such as pushing the terrain away so that I may place objects there instead.
I would also love to have two shader effects added: Sea (over and under water) and Stream (over and under water). See CryEngine for what I am looking for.
I would also like a button to disable terrain clipping of painted objects. It would make my life in cleaing up and editing much easier
These do also paint holes in the collision mesh for the landscape.
As for sea and stream, the major issue here is with translucency. Unreal’s translucent materials have some rather large issues at the moment, and while getting something reasonable is possible, a material like the one in CryEngine is not. Epic have said they plan to work on this, but not in the near future.
I’m not entirely sure what you mean by “terrain clipping” of painted objects. Could you expand a little on that?
