PBR Settings Window

The PBR Settings window is the primary information control center for OctaneRender^®. It monitors GPU performance, enables out-of-core rendering, and monitors RAM and VRAM usage. Account information and the Octane log are found here as well. You can access this window from the Octane menu (Figure 1).

Most importantly, this window is where you activate the OctaneRender engine for a Unity^® scene. To activate OctaneRender, click on the Load Octane button (Figure 2). This activates the information and checkboxes (Figure 3).

The Devices rollout lists the current GPU used for rendering along with a series of checkboxes:

• Active - This activates the OctaneRender engine to render a Unity scene. If this checkbox is disabled, you can navigate the Unity scene with the PBR Viewport updating the rendering.
• Use Priority - Determines the GPU that OctaneRender uses first in multi-GPU machines.
• Use For Tonemapping - Enables real-time tonemapping to build the preview image in the PBR Viewport window for specific GPUs.
• Use For Denoising - PENDING DESCRIPTION FROM MAXC

The Out Of Core rollout addresses how rendering occurs once the GPU runs out of RAM:

• Enabled - Activates the Out-Of-Core rendering feature.
• RAM Limit (GB) - Specifies the amount of system RAM used for Out-Of-Core rendering.
• GPU Headroom (MB) - Minimum amount of GPU memory to keep as a buffer during Out-Of-Core rendering.

The Baking section provides functions for batch baking object materials and lighting that are in development and not yet fully supported:

• Bake - Starts the batch baking process for all Baking Group IDs.
• Apply Baking Results - Applies the baked textures to the appropriate assets in the Unity scene.
• Revert Baking Results - Removes the baked textures from the scene assets.
