Reply to comment by Riot55 in [OC] 3D Render of a 2000 Geologic Map of Utah Created in Blender by BigBallerBenzie

Unsure of Sketchup and Lumion, but at least for blender, I got my start by using the tutorial linked:

If you want to create your own custom landscape WorldCreator is also amazing:

In blender, you can also create a pretty realistic landscape using noise textures or geometry nodes. There are plenty of good tutorials, or I just made a pretty complex one that I put on Blender Market that is fully procedural and customizable:

Great to finally see some tips on how to build something like this here (rather than just sell a print)! Any other tips?

Lots of stuff comes to mind :) One of the most useful to me was using the elevatr package (https://github.com/jhollist/elevatr) in R to get much more high-quality terrain data using the code below:

​

library(elevatr)

memory.limit(size = 10e10)

topo_map <- raster::brick("name of georeferenced file.tif") topo_map <- raster::stack(topo_map)

elevation <- get_elev_raster(topo_map, z = 13, override_size_check = TRUE) elevation <- raster::crop(elevation, extent(topo_map))

writeRaster(elevation, "output name for file.tif")

Z will be the quality 1-15

Watch videos on QGIS on how to georeference (sometimes I will just do a rough outline to get the general area covered), and also how to import this file into QGIS and transform it to 8 or 16 bit so it is usable in blender
