Does anyone know how to fix this error when attempting to import a slope map from Gaea? UE 5.3
Attempting to place a slope mask on a specific landscape layer,
The landscape extent reporting 0x0 hints at an engine bug being present…
Check what the real extent of the specific tile is.
Also, its a warning. Doesn’t mean its going to clip anything in actuality, so what happens when you proceed?
As a plus, make sure the texture has the same channel on all 3 channels RGB.
And that its saved up as a png. Shouldnt matter, but you never know.
When I click ‘ok’ to proceed, no change is made.
“Check what the real extent of the specific tile is.” how would I do this, exactly? Kind of a neophyte here… 
I do know for that some reason my landscape imported with multiple proxies… I’d really rather have just a single landscape node as when I have to replace the material instance I have to ensure ALL notes are selected as opposed to just selecting ‘Landscape’. Could this be the issue and if so, how can I fic it?
Open up the specific landscape tile/level, or select it if its already open, and look at its settings.
Alternatively you could try to create a new persistent level to import the heightmap and splat map all in one shot.
If it’s an engine bug, you may be able to get around it that way…
Well, it doesnt actually include the warning, so we cant really help.
But if its giving you that, you may just want to try the fresh import pathway instead anyway…
I’ll give that a try. Ta for all your help thus far.
Is there a way to import the heightmap as non-partitioned or do you think that even matters?>
Depends on size mostly.
The engine can handle up to 8km but the performance for levels in that size is usually bad (due to the amount of components they have and the size of each individual component making it near impossible to reduce tris load).
If the engine fails at it, again… i auggest tou get 4.18 and give that a try.
The landacape works much differently there.
If you want to risk it because you need newer stuff etc, the latest 4.2whatver is probably a good place to go to.
Compared to .18 is still not going to work and perform its best, but it should get you in a state where you can create and setup whatever you need.
Once you have it created you can then make a hard copy and convert one of the copies to the lateat engine to see if it works/how it works etc.
Aside from this,
You can always download Houdini and study up on how to use it for importong massive size words made out of meshes - which are going to perform some 300% better than landacapes ever will (even with nanite).
I’ll look into Houdini. Thanks again
*edit: It works fine in 5.4… bug in 5.3 I guess
