Got "high" with some astronomy, went to the deep trenches of the Milky Way, and took this picture.
Software used: ZBrush + Maya + Photoshop + After Effects
The whole process of creating this concept was extremely fun!
I started by creating the tree in Zbrush using Z-Spheres to get the overall shape of it. I then proceeded to Maya to create the abstract shapes that represent the glowing leaves and fruits for the tree.
The grass, although barely visible, was created using Maya Paint Effects.
The nebula was created using Maya fluids and rendered with mentalray, which renders much faster than Maya Software. Had to do some optimizing in the shading and resolution for the fluids to speed up the render time. I also added some extra nebulose-like items to the main nebula in photoshop.
The glows were achieved using mia_light_surface and rendered with final gather.
Hope you guys like it!
