What is Octane X?
Octane X is the macOS / Metal version of OctaneRender. It's a production-quality path-tracer used in the film & VFX industry. It has been available for many years as a Windows-only NVIDIA-only product. But the task for this specific project was to get OctaneRender running on macOS, which obviously brings along a large swath of challenges:

• a completely new OS (macOS)
• a completely new graphics API (Metal)
• a bunch of new GPU architectures (Intel, AMD, Apple Silicon)

Unfortunately I can't share exact details of what was done to make this happen, but I can (vaguely) point out some of my personal contributions. I was on the team that built the low-level porting tech necessary for the Octane dev-team to move to macOS/Metal. We dealt with figuring out platform issues/differences and doing lots of low-level problem-solving. To top all of that off, we also built the tech necessary to ship GPU code securely on macOS - which is mission-critical in the VFX industry where leaking your sensitive algorithms could mean the company goes under.

Contributions

• Building low-level porting tech
• Dealing with cross-vendor GPU architecture differences
• Building tech to securely ship sensitive GPU code
• Provide support to the Octane dev-team
