72 Martian Landscapes based on real height data "HiRISE" shared by NASA's LPL labs (NASA/JPL/University of Arizona) I processed the height maps and made the Textures using World Machine 2.
Terrains in this package are:-
19X Impact Crater/partial Crater
15X Random Grounds
20X Random Ridges
12X Sand Dunes
(Disclaimer: some of the terrains still have visible lines and errors from the raw scans, as the Mars Reconnaissance Orbiter scans the terrain in strips)
All Terrains come with:-
3X Obj poly sizes 40k/1mil/4mil
5X 8k diffuse textures 8bit Jpg
2X 8k Normal maps 8bit & 16bit png
1X 8k Processed Height map 16bit Tif
1X 8k flow map 8bit Jpg
(649 8K textures in total 53Gb, complete package with obj's 82Gb, but most wont need the full pack)
files are broken up into separate zips for convenience
Textures are 8192 pix longest side, as most terrains are not square
There are two texture zips "Advanced" (includes 3 textures) and "Basic" (includes 2 textures), basic is what I used with the flow maps to make the advanced textures.
A 8K demo scene (main cover) is also included, with a free Fog VDB too, you will need 3dmax 2015+vray3 to open the scene, but the VDB can be used in many 3D programs.
Also watch out for the Obj zip sizes compressed / uncompressed
Obj mesh high 1mil.zip 3.6Gb / 12Gb
Obj mesh original 4mil.zip 3.6Gb / 21Gb
I've uploaded the 4 Million poly originals just in case..but most will not need them, the 1 Million poly Obj will do fine.
PS, If you have any questions please don't hesitate to contact me on ARTStation
A big thank you goes to HiRISE/Lunar & planetary laboratory/JPL for their high res scans of the Martian surface. hence the low price as I'm only asking for my time making the textures and processing the files. the files from NASA/JPL are copyright free but I'm not giving the original height maps, but instead my processed height maps that have added erosion and are smaller in resolution etc.
