Once you assign the Material Instance, black/white colors will appear on your terrain. This way we can adjust the parameters in real-time without having to save and compile the Material every time. We are going to assign the Material Instance rather than the Master Material. Under Landscape Material search for Auto-Landscape Material Instance. Select the Landscape and go into the Details Panel. Simply assign a Material onto the landscape and it will begin to work. Here is what I have:įor Auto-Landscape Materials you do not need to create Layer Info as you would with regular landscape materials. You need to have a terrain with some hills, valleys and peaks to apply the Material onto. Step 3: First Auto-Landscape Material Test Repeat for Blend Bias.Īpply, Save and test. Right Click on Blend Sharpness and choose Convert to Parameter. Right now we don't have anything plugged into them so Lerp will display Black/White values.īefore we test lets convert two Constant1Vectors to parameters so we can adjust them through the Material Instance. Lerp A and B would take color or texture inputs. This is the fundamental setup for Auto-Landscape Material. Then Lerp output into Base Color of the Material: Next you need a Linear Interpolate (Lerp) node.Ĭonnect Alpha output from World Aligned Blend into Lerp Alpha. I will set Blend Sharpness to 15 and Blend Bias to -5:Ĭonnect first Constant1Vector into Blend Sharpness and second Constant1Vector into Blend Bias: Set default values to start with for each Constant1Vector.
Blend Sharpness: controls the blend sharpness between the two textures.
The two important properties you need to control are Blend Sharpness and Blend Bias. Inside the Material Editor, Right-Click in the empty space then search to insert World Aligned Blend node. The basis of all Auto-Landscape Materials I create is World Aligned Blend node.ĭouble click on the Material to open Material Editor. We'll get back to the Material Instance later in Step 8. Inside the Content Browser, Right Click on MAT_FirstAutoMat and choose Create Material Instance, then name it: Right away I want to create a Material Instance so I can make adjustments to this Material and see updates in real-time. In Content Browser, click on Add New and choose Material:
