I make 3d scene with blender. Export obj format ( work well ).
When i will try make some bush and tree with transparent png texture
mesh.material.alphaBlending = true
mesh.material.alphaThreshold = 0.5
After all is looks fine I faced Z-order problem:

How can i solve this problem without z-sorting tree manualy by angle of view?
