Creating Trees in Maya – Onyx by Alex Alvarez

This course dives into creating stunningly realistic CG trees and populating entire environments using the powerful combination of Onyx Tree and Maya. You’ll learn practical scene layout and rendering techniques that are essential for anyone building natural CG worlds, from quick tree generation to complex forest scenes.

🎯 What you’ll learn

• Quickly generate diverse, physically accurate trees with Onyx Broadleaf.
• Export tree geometry and wind animation from Onyx to Maya.
• Manually animate tree leaves using softbody lattices.
• Implement physical sun/sky, final gather, and miaMaterials for realistic tree rendering.
• Create custom leaf textures from scans.
• Build an overgrown highway scene with 4k compositing in After Effects.
• Render beauty, Zdepth, and fog passes.
• Utilize Lenscare, Magic Bullet, and Sapphire plug-ins for post-processing.
• Explore Onyx Conifer, Palm, and Bamboo for specialized tree types.
• Achieve photorealistic results in deep shadow environments.
• Implement Mental Ray proxies for handling billions of polygons.

✅ Requirements

• Skills: Basic understanding of 3D concepts, familiarity with Maya’s interface.
• Tools: A 3-button mouse is recommended.
• Hardware: A dedicated GPU is beneficial for rendering.

📝 Description

This course is your guide to integrating the Onyx Tree suite into your Maya and Mental Ray pipeline. We’ll start by mastering Onyx Broadleaf to generate a vast library of realistic trees, covering everything from exporting geometry and wind animation to Maya, including a custom Gnomon mel script. You’ll also learn how to manually animate leaves using softbody lattices for quick results.

The course then delves deep into rendering, with thorough demonstrations of physical sun/sky, final gather, and miaMaterials specifically tailored for trees. We’ll cover creating custom leaf textures from scans, culminating in the creation of an impressive overgrown highway scene. This scene will be composited in After Effects at 4k resolution, incorporating beauty, Zdepth, and fog passes, along with post-processing effects using Lenscare, Magic Bullet, and Sapphire plug-ins.

We’ll continue by exploring Onyx Conifer, Palm, and Bamboo, discussing specific library and rendering techniques for each. This includes achieving photorealistic results in challenging deep shadow environments using advanced final gather techniques. Finally, we’ll wrap up with a look at Mental Ray proxies, a crucial methodology for environment artists needing to populate scenes with billions of polygons efficiently. Alex Alvarez shares his extensive knowledge, aiming to inspire artists to explore the rich world of CG natural environments.
