How do you use the "Get Altitude" node and take it into a luminosity shader and render it into a heightmap with a top-down camera?
I'm asking about the node workflow itself. I'm new to TG4 and don't really know how the nodes work together. I would really appreciate someone explaining to me which node goes with which and in what order.
I've read in the forum about someone using Linear Step so they can get a gradient using terrain altitude and then render with a top-down camera, but couldn't replicate that on my own:

Because I've tried the "Heightfield Generate" node, and I think the quality of the save file is not as good as rendering a "luminosity Shader" with a top-down camera render where I can adjust "Micropoly detail".
Ultimately, I want the best resolution heightmap possible from TG4 so I can save it as an EXR or TIFF and use it in other render engines like Octane with Cinema 4D.
I don't really need a Vector Displacement for overhanging, just a scalar displacement will be fine. And no need for a tiled map for now.. just the best quality single 8k heightmap TG4 renderer can provide, if that's doable.
Thanks for reading
