Undo does not undo terrain sculpt

[thehankinator]

When I am sculpting the terrain and make a mistake, undo reverts the last change I made before the sculpt not the sculpt operation. Is this a known issue?

It is not possible to make this work like you think because the memory requirements of storing all those undo steps would quickly get out of control.

One 'Undo' will be enough in 99% of all situations I think.

One terrain undo would be nice or maybe clear the undo history when working on the terrain so no surprise undos. Once you've moved onto editing terrain you're not likely to want to undo previous object edits I don't think.

I assume the memory issue would be the fact that you have to store an array of vertices, probably around 50MB of RAM at 4096 terrain size?

 

Maybe it could be a toggle-able option where we could set the size of this "undo" buffer. For example, I wouldn't care if I had 10 frames saved.

 

I personally have 12GB of ram on my computer, so I wouldn't mind LE using the maximum 3 gig of ram.

 

Granted for my Laptop, I would want a lot less of a buffer size, maybe even 0.

 

My concern with an undo, buffer is the CPU processing required to generate these. I find terrain modifying to be semi-taxing on my current map as it is some times
