After I made my landscape material and added it to my landscape, I went in to start painting the different textures. I realized I made a little mistake with the path material, so I tried to cover it back up with the dirt material, but nothing happened.
It seems I can remove some of it by holding Shift and left-clicking, but only small amounts of the texture come off when I do this.
I’m completely new to landscape painting. I just want to be able to click and apply a texture. This should be simple, right?
That just has to do with lighting options.
Your world is whatever you configure and set up.
The material preview is a closed environment with probably the best light the engine is capable of (arguable?).
Could be due to your brush settings.
Either way, normally landscapes are additive only.
A base layer which is omnipresent on everything, to which you add other stuff on top.
Within the material you can subtract before you add - or do whatever you want - or just use the engine provided layer code stuff which does it for you.
It will still work by Adding and Subtracting a layer from the zone/mix.
Assuming you have everything set up correctly, you can delete a whole layer or paint a whole layer in by just rightclicking the layer and selecting the option.
If your landscape is Black at the beginning, your materail is wrong - see the point above about there being a universal base layer.
Is there a known lighting setting that can make things consistent with how they appear in the material preview? I’ve got dark brown textures coming out bright beige.
Probably not - the material preview is basically a light box based (hri image of unreal HQ) system.
It includes reflections and a bunch other things that are just not avaliable and should not be avaliable in your final scene.
That said you could also have other issues going on.
The material preview is set up with default values for the painted layers. The weight of each layer is selectable in your left hand panel.
Thus, iit’s possible you have a shade set to 50% therefore what you see on the landscape is accurate vs what the material preview shows you.
If you are choosing colors into an instance, its generally desired to view the resut in Pie and go off of that instead of focusing on the material preview…
