Hi Sam, this tutorial was excellent, thank you for creating this. Is it easy to drape a tiff image over the top of a 3d map like this? I have an elevation map and a tiff of the same area for my project

Looks like it's possible here: www.rayshader.com/reference/add_overlay.html
Though I haven't tried it myself yet.

@@Piemaestro Thanks Sam, I have been trying for several days (not proud to admit that!) but I still cannot overlay an image. My images are definitely correct, and they both have the same dimensions. Both images are TIFF format, but I think I have to convert one TIFF into an RGBA file, but the 'readTIFF' function will not convert it for some reason. It would be an excellent addition to this video though, I am sure many people would like to know how it is done. It would be good to use an overlay as a visual reference layer

@@Pro_Skillz would this work? convertio.co/tiff-rgba/

[@Pro_Skillz]

@@Piemaestro I tried that, but unfortunately the file size is too large. I might have found a workaround, I will come back if im successful. Difficult task!

@@Pro_Skillz I use photoshop for these projects sometimes

Hi, I haven't worked with overlays much- you may want to ask ChatGPT
