Moving on from this issue as it cannot be surmounted at this time.
I will be releasing two volumes called Mega Bush 01 and 02.
Volume 01 has 19 unique meshes that can be combined, and or used individually, to create more unique bushes, or 1 to the power of 19. Combined with the 20 unique leaf materials that can be used on each mesh (each mesh takes 2 leaves and one branch material), potentially you can make 144,400 unique bushes from a single volume.
Volume 02 will share the same materials as Volume 01, but has yet another 20 unique bush meshes, that will give any scene creator a mind boggling amount of permutations for creating unique bushes in their scenes. With both Volumes and the mixture of materials, the total number of unique bushes you can make is 608,400 unique bushes (39 meshes squared x 20 leaves squared) this is not including rotating the meshes within the cameras view, tinting and scaling!
In addition, you can add your own leaves and even flowers to suit your needs.
In the selection of leaf materials/textures are also a collection of dead and dying leaves to create seasonal bushes.
I will post here once the volumes become live in the MarketPlace.
