Rendering

Path Traced Rendering in Omniarch provides high-fidelity image output by simulating the behavior of real-world light ray physics. This technique calculates accurate lighting, reflections, and shadows for photorealistic results, making it ideal for architectural visualization with cinematic quality results.

Rendering panel can be accessed by clicking on Rendering Icon in the Main Toolbar on the left edge of the UI.

Rendering is meant to be used with Cinematic Cameras, allowing users to capture precise shots and export them with extended visual control.

Rendering Parameters

Output

• Resolution Preset – Quick preset dropdown to choose output image size from. By default it contains standard 16:9 resolution presets (1080p, 1440p, and 4K). This parameter is based on the Cinematic Camera aspect ratio Image Crop, if enabled. It generates three dropdown presets with multipliers (1x, 2x, 4x) calculated from the Image Crop aspect ratio.
• Image Width / Height – Offers custom image output resolution in pixels. Width and Height are defined by Image Crop aspect ratio in Cinematic Camera Settings UI.
• Flip Resolution – Swaps width and height values, useful for changing between landscape and portrait image format.
• Filetype – Sets the image file format for the output render (currently PNG and JPEG are supported).
• Watermark – Adds Omniarch watermark on the final rendered image.

Quality

• Renderer – Defines which rendering engine is used in the pipeline:
  • Path Tracer for highest quality physically-based, high fidelity rendering. This mode uses real ray bounce simulations to achieve accurate global illumination, soft shadows, reflections, and light scattering (especially beneficial for translucent materials and indirect lighting).
  • Real-Time to capture the real-time lighting with highest scalability settings.
• Denoiser – Removes noise from path traced renders.

Denoiser is a work in progress and it's currently very robust and may smudge fine details on final renders. For best results render with higher sample counts and higher resolution with Denoiser off (more denoising control parameters will be added with future updates).

• Screen Percentage – Adjusts the native rendering resolution as a percentage of the output resolution. This effectively scales resolution, resulting in higher fidelity image at higher values (this setting relies highly on VRAM and multiplies with image output resolution, overdoing quickly depletes hardware resources which results a crash).
• Temporal Samples – Sets the number of samples accumulated over time, enhancing motion clarity and reducing noise in dynamic scenes.
• Spatial Samples – Sets the number of rays calculated per pixel in space, improving fine detail and overall image sharpness.
