3D models of two ripe red apple trees created in Blender and imported to Unity 5. Textures used for branches and tree crown are pictures that I draw myself using GIMP.
Texture for tree bark is 884:1724. Texture for grass is 2592:4608. Textures for branches are 507:338 and 1000:1000. Texture for crown is 221:317. Total polygon count is about 13000. Albedo maps used.
With my skills developing more and more, I will continue to update models that I upload. In update 1.5 I already added second variation of the apple tree and In the near future third variation of the apple tree will be added to the package with more polishing to the original models.
