Each log is a single object, made from multiple combined meshes for the wood and bark.
Each 3D model comes with 3 levels of detail (LOD). The UVs are non-overlapping. A second UV set is also offered for lightmaps. The first UV set contains the 4 logs, as they share the same textures, but each log has its own lightmap UVs.
Every object is centered, without rotation and a scale of 1.
The models share a single material, with color and normal maps. The textures have a resolution of 4096x4096 for maximum detail, but can be reduced with good results for real-time uses.
----------------------- File formats
Each format includes 3D models and textures packed together in the same download.
Blend- All logs and their LODs are placed on different layers, centered and ready to be exported. The scene is set in the blender internal renderer, which was used for the previews.
Maya 2018- All logs and their LODs are placed on different layers, centered and ready to be exported. The scene is set in the Arnold renderer, as it is the default renderer in Maya 2018.
FBX- Each model and LOD has its own FBX file, ready to be imported in other software.
OBJ- Same as FBX, included in case FBX is not compatible.
