 In this DVD, Alex covers how to create realistic grass using Maya, Paint Effects and Mental Ray while also sharing his techniques for developing a complete natural environment. We begin by evaluating the default Paint Effects grass library with discussion on the basic adjustments needed to make grass more natural. Techniques for covering large areas with grass are then explored via curves and instancing. Through the use of instancing, particles and surface emitters, Alex shows how to populate large scenes with grass geometry, rendering millions of polygons with a minimal RAM footprint. Included is an expression based technique for orienting instanced geometry with the normal of the generating surface, an issue less important for plants or trees but often very important for grass. When elements need to be interactively and precisely placed, Alex also demonstrates the use of a freely available geometry paint script, as well as how to bake particle instances to geometry. Generating textures, miaMaterials and workflow in conjunction with Physical Sun/Sky is thoroughly discussed. Alex also demonstrates how to render and utilize zDepth passes to add post depth-of-field and fog effects, how to render true volumetric fog effects, as well as Photoshop and After Effects post techniques to increase realism through the use of color correction and plug-ins, including Magic Bullet, LensCare and Sapphire.

This DVD explores how to incorporate the Onyx Tree suite of programs into a Maya and Mental Ray workflow, while demonstrating scene layout and rendering techniques that apply to any artist interested in natural environments. We begin with Onyx Broadleaf, an invaluable tool for quickly creating a diverse library of physically accurate trees. The user interface is explained while demonstrating how to export geometry to Maya, including wind animation and a custom Gnomon mel script for importing Onyx animation. Beyond Onyx animation, we also look at how to use softbody lattices to manually animate tree leaves for quick turnaround animation. A thorough demonstration of physical sun/sky, final gather and miaMaterials for trees is then provided including a detailed review of how to create custom leaf textures from scans. Broadleaf techniques culminate in the creation of an overgrown Highway scene with a final 4k composite in After Effects that includes beauty, Zdepth, fog passes and post-process effects with the Lenscare, Magic Bullet and Sapphire plug-ins. Moving on, we then explore Onyx Conifer, Palm and Bamboo in equal detail discussing library and rendering techniques for each type of tree concluding with a photorealistic bamboo forest that introduces final gather techniques for deep shadow environments. We wrap up the DVD with a demonstration of Mental Ray proxies, allowing environment artists a methodology for populating scenes with billions of polygons. Suited to both students and professionals, Alex shares his in-depth knowledge hoping to inspire artists to delve further into the world of natural CG environments.
