Hey !!
here is more rock-material and a DOWNLOAD - I personally love this one for rock-walls.
Also cool for sculpting ;)
Scandata: 70.000.000 points / 16.000.000 polys
Here is a FREE set for testing purpose:
https://dl.dropboxusercontent.com/u/95809473/ROCK_002-chalkstone.zip
All maps are 8k only Displ in 8k8 and 8k16.
There are two different bumps as well as normals - one is more, the other is less focused on details.
You definitely should not use all maps together - there are many maps that should simply give you more flexibility to build different cool materials.
Especially this one is originally in vertical position and its weathered - so you have to take care in with direction you map the material on your object - there is a upside.
Just for testing - these are only the maps and no ready to use materials - please just try out.
- and PLEASE be kind and give me some feedback. positive or negative. It helps me developing a good pack for you ;)
thnx
