Meteor Crater, Arizona

Description

This scene is for blender 2.78
It recreate the meteor crater from very dense lidar points cloud.
i had to downgrade my original textures size to fit the max upload size. Original file weight more than 2GB !
You'll probably need to unpack all textures (file->external data->Unpack all into files) to render the scene correctly as the displacement map is a 32bit one (and i don't know why but the plane stay flat when this file is packed)
The scene is optimized for GPU rendering on a 4GB Vram card, to acheive better quality or lower memory, you'll have to tweak the render subdivision rate in the geometry section of the render panel. 0.33 is for GPU rendring, if you have time, switch to CPU and decrease to 0.1 (you'll need 32GB ram, put 0.25 for 16GB)

There is a problem with the height map

you have to unpack it to make it work, i don't know why but when the file is packed, the plane stay flat, but if you unpack it, all works as expected. ( i think it is because it is a 32bit tiff and blender is not supposed to support it) i explain how tu unpack (just in case you don't know how to) in the description.

I did save the file first , I unpacked the file . The file appears to be Black at all points In the image editor ctrl click a point the get the coords and the values all read 000 in RGB or HSV. Do you have external link to texture? Am I Missing something

it's almost "normal". this file is a 32 bit elevation data file with a verry wide range, if you want to see something, open it in photoshop or gimp and use then "hdr turn" function and adjust the contrast/luminosity. it produce elevation datas for the displacement mappping but don't produce good visual datas.

What is the source on your images? USGS?

Usgs elevation datas genrally have a 30 meters resolutions, 10 meters in some parts of the World. The lidar cloud points i used have a resolution of 10cm.

Looks cool! I think that there might be an American flag at the bottom though. Just a suggestion. :-)

Thanks ! your low poly version is verry nice too ;)

This model is awesome, but too low-res for me. Can you provide the original high-res textures on a cloud ?

you may upload your heavy texture elsewhere.
