@hinerl01 Yes, you can create a megatexture. Hell, you can create a mega-material (with PBR based layers). Even using outside file textures.
That’s not what this topic was about however, next time please create a new topic when you want to ask an unrelated question. Read on if you need some more details.
Workflow or feature summary, oversimplified
You can import outside files using either “file” generator, or PBR material using “Material” generator (this one is also used to procedurally create a material). For the exports, use a corresponding output node. “Bitmap output” for a single RGB texture, “Height output” for black and white masks, “Material” output for PBR material layers (you can also use bitmap outputs for individual PBR layers, but material output does all that automatically, much faster to set up)
To combine different textures in world machine, you can use either “Combiner”, “Chooser”, or “Layers” nodes (depending on what kind of combination you are trying to achieve). You can create all sorts of megatextures, and even whole GLTF scenes, using World Machine.
Here are some megatextures I created entirely using world machine
Made some threads on the forum itself about some of them. First link is the gallery, the rest are separate forum threads about some of my works:
