STEP BY STEP BUILD A TERRAIN WITH GAEA’S LOOKDEV NODES

-

01 BASIC TERRAIN SETUP

Start a new project. When loaded, delete the Mountain node. Go to Geoprimiti­ves in the Toolbox and drag Worselands into the graph view. Connect its output to the Erosion node input. In Properties, set the Worselands seed to 2862. Set Erosion's seed to 2254, and Random sedimentat­ion to 310. From Lookdev, grab the Stacks node and drop it onto the Erosion node. Set the Stack node's seed to 2938, and set Fold to 37%.

02 SOFTEN THE TERRAIN, REMOVE ARTEFACTS

We'll fix sharp edges and artefacts by adding Blur and Fold nodes between the Worselands and Erosion nodes. Drag a blur node onto the Worselands node; it will automatica­lly connect them. Next, drag a Fold node onto the Blur node. Then, connect the Blur node's output to the Fold node's output (yes, two connection­s) – this will automatica­lly create a Combiner. Connect it to the Erosion input, and then set the Fold seed to 4576.

03 ADD DETAIL

In the Stacks node, ensure Talus Pass is on, and its power set to 0.15, Encourage Strong Flows is on, and set to Sedimentar­y. From Lookdev, drag a Canyoniser node onto the Stacks node. Set Maximum depth between 4 and 2, and seed to 4576. Press CRTL+D to duplicate and create another Combiner as described in step 1/2. Play around with the second Canyoniser's seed for contrast. Next, drag a Surface node onto the Combiner.

04 ADD TEXTURE AND SET UP TERRAIN MAP EXPORTS

Set the Surface node's strength to 48, and Density to –13 to generate a surface texture. Next, drag a Texture node onto the Surface node, and a Satmaps node onto the Texture node. Set the Satmaps node to Sandy, gradient nr 0147, and check Jitter, input Clarity and Input Auto Level. Finally, select all your nodes, rightclick and mark them for export, and click the Build tab to export your terrain and its maps.

HOLLOWING

I used to hollow things in Zbrush, but now almost all 3D print slicing software comes with an option to hollow out a model. You need to have a hollow model to save on resin if you are using a resin printer, so having a good clean model before you export it is essential. Focus on making the geometry as good as you can and leave the slicing software to calculate the hard stuff!
