A pack of 3 game ready spruce trees. They have varied shape and size and have roots that extend deep below the end of the trunk into the ground, so they can easily be placed on various terrains and slopes without the borders being visible.
----------------------- 3D models
Each tree is a single 3D model. The pivots are placed at the base of the trunk, with the roots extending below into the ground.
Each 3D model comes with 3 levels of detail (LOD). The main UVs are overlapping, but a second UV set is included for each model which has non-overlapping UVs. That second UV set does not match between the LODs as they have different topology.
The models have 2 materials: bark and branches. Each material has color and normal maps. The branch color texture also has an alpha layer for transparency.
(Note that the alpha layer may need brightness and contrast adjustments depending on the software used. The texture involves finely detailed branches, which means that the tree may look too transparent or opaque depending on how each software handles transparency.)
The bark texture has a resolution of 2048x2048 and the branches texture has a resolution of 4096x4096 (2048 for each of the 4 branches). The textures have more detail than needed so they can easily be reduced in size as necessary.
----------------------- File formats
Each format includes 3D models and textures in the same download.
Blend- The models and their LODs are placed on different layers, ready to be exported. A layer is also included with the branches used to build the trees. The trees are setup for internal renderer, with the influence of their alpha layer adjusted in Blender to the desired level of transparency.
Maya 2018- The models and their LODs are placed on different layers. The render is setup for Arnold, 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.
The previews are rendered in the Blender version (internal renderer). The alpha layer is adjusted in the software to the desired level of transparency. Most images include a small amount of ambient occlusion, since it improves the visual aspect of 3D trees.
