Render Modes#

Camera sensors in ovrtx support three render modes, each offering a different trade-off between image quality and performance. The render mode is set per RenderProduct using the omni:rtx:rendermode attribute.

def Scope "Render" {
    def RenderProduct "Camera" {
        int2 resolution = (640, 480)
        rel camera = </World/Camera>
        rel orderedVars = [<LdrColor>]

        # Select path-tracing render mode
        token omni:rtx:rendermode = "PathTracing"

        def RenderVar "LdrColor" {
            string sourceName = "LdrColor"
        }
    }
}

Available Modes#

Mode	`omni:rtx:rendermode`	Description
Real-Time Path-Tracing	`Real-Time Path-Tracing`	Full path-traced rendering with real-time denoising. Produces high-quality images with accurate global illumination, reflections, and shadows. This is the default mode and the best choice for most applications requiring visual fidelity.
Path Tracing	`PathTracing`	Progressive path tracing that accumulates samples over multiple frames for ground-truth-quality rendering. Best suited for offline or reference-quality workflows where convergence time is acceptable.
Minimal	`Minimal`	Lightweight rasterization-based rendering with minimal GPU cost. Use this when you need maximum throughput and do not require path-traced lighting – for example, segmentation masks, bounding-box visualization, or high-FPS reinforcement learning loops.

Choosing a Mode#

Default to Real-Time Path-Tracing for sensor simulation, synthetic data generation, and any workflow that requires physically accurate lighting.
Use Path Tracing when you need converged, reference-quality images and can afford to accumulate samples across frames.
Use Minimal when rendering throughput matters more than visual quality – for example, thousands of environments stepping in parallel for RL training.

Different RenderProducts in the same scene can use different render modes. For example, one camera could use Real-Time Path-Tracing for RGB output while another uses Minimal for fast segmentation.
