In this collection you get fifty different and unique stones. You can use these for many CGI stuff. here there are two subdivisions once a low poly version with uvs and a high poly version without uvs for procedural shading.
the low poly stones have a resolution between 15 and 20 thousand polys.
The high poly stones have a resolution between 2.5 and 4 million polys.
The high-resolution stones are very well suited for macro CGI recordings. With the low poly versions you can build landscapes very well.
