My setup is a 5700X, 32GB of RAM, and an RTX 3070. I usually work with 4K landscapes, but the performance is terrible — it hangs a lot when painting, sculpting, or doing pretty much anything in that mode.
I’d like to know if there’s any tweak I can try, or if that’s just the expected behavior.
Hi, you can disable “edit layers” (I think it was called something like that) in the landscape if you do not need it.
Hey thanks, if that does what I think it does then I need it, because I have a multi layer landscape material.
You don’t need edit layers enabled for a multi layer landscape material. What edit layers does is to allow you to add ‘layers’ to the landscape that can be edited (sculpted or painted) separately and are in the end blended together (which makes editing the landscape slow though). Without the edit layers enabled you only have a single layer. The idea for the multiple layers would be to modify the landscape in a non-destructive way (e.g. if you want to place a building somewhere you may need to flatten the landscape where its placed, with edit layers enabled you can do that flattening in a separate layer and therefore still keep the original landscape data in case you want to move the building).
The other option I know of would be to use a smaller landscape (or maybe instead of one large landscape use multiple smaller ones, never tried that though so don’t know how that will perform runtime).
I see, I will give that a try then, thanks.
Disabling “edit layers” in the landscape didn’t help.
Remove the foliage. see if that helps.
Yep, the sculpting tools work totally smoothly after removing the foliage, but I can only do that for testing purposes. Any workaround?
Any fix for this?
The only way I can sculpt the landscape is one click at time, and the results appear 5 seconds later, to drag the brush is impossible. I’m totally unable to work like this.
I checked for any option to temporarily disable the foliage, but it doesn’t seem to exist.
Likely ots an issue with your foliage and the complexity of their collision.
Try to see if you are limited by something else.
Make and paint the engine box as foliage with trandom transforms in obscene quantities and see if the behaviour is the same or not
If its not, then fix up your models. If it is, then the version of the engine you are on is bugged, or your hardware is just not up to the task.
I only work with marketplace assets and it happens with any of them.
I re enabled edit layers in the landscape and it improved, at least now I can drag the brush for a while before the freeze.
Doesnt mean anything.
Unless you made the assets yourself you cannot be sure they arent just trash thrown together in a rush using wierd collision hulls.
I’d recommend checking your computer’s resource usage while sculpting. It might be a hardware limitation—most likely your RAM. If that’s the case, I suggest working with a 2K landscape, which is more than enough in many situations.
Also, if your foliage is driven by your landscape material, you can temporarily disconnect the foliage part in your master material while you work, and reconnect it afterward.
If you still want to see how your foliage behaves while sculpting, consider replacing it with a low-poly proxy mesh, and switching it back to the original mesh once you’re done editing.
Lastly, if you’re still experiencing performance issues, you can disable the landscape’s collision while editing, then enable it again afterward.
That should help!
