Hi. First of all Thanks to Temanibble for awesome tutorials. AND you are life-savior
At work, my boss asked me to find how to create the black and white bump map without losing DEM data.
He did not know how to do, so I did research whole day and I ended up with this tutorial.
To simply this workflow.
1. get DEM images from open topography webstie.
2. Using Microdem which is a free software, convert it into greyscale bump map
3. Using 3D softwares, (ex, Cinema 4D, MAYA, 3D MAX)
