A new build of the RTX Render open beta is now available: Beta3_0917.
Following our initial beta releases, Beta 3 introduces major feature additions—including native Volumetric Lighting, a dedicated Lens Flare post-processing channel, and physical Lens Presets with Sensor Shift alignment—alongside core architecture refinements to Substance materials, World Lighting, and Denoising mechanics.
For a complete walkthrough of all features, workflows, and visual examples, check out our full guide:

RTX Render Open Beta 1 Overview & Getting Started
Enhancements
1. Substance Material Integration
- Preserved Depth: Substance materials retain their full 3D surface structure and depth when converted to RTX—no baking or flattening required.
- Live Parameters: Substance material parameters remain fully adjustable in real time within RTX mode.
- Animation Support: Keyframing Substance parameters functions as expected in RTX. (Note: Real-time playback is ~3 FPS in RTX mode due to current performance bounds, compared to ~60 FPS in DX11).
- Known Limitations: Displacement and Ambient Occlusion (AO) effects are currently unsupported in RTX rendering.
2. Lens Flare
- Enhanced Visuals: Refined lens flare controls and direction settings for improved optical quality and control.
3. Volumetric Light
- Expanded Support: Volumetric lighting is now supported for Spot Lights and Point Lights. (Directional Lights are not yet supported).
- Note: Volumetric light currently does not pass through glass materials in either RTX or DX11.
New Features
1. Advanced Camera Tools
- Lens Presets: Choose from realistic lens profiles including Prime Lenses (e.g., 12mm f/2.8), Zoom Lenses (e.g., 24-70mm f/2.8), and Universal Zoom (unrestricted 20mm–200mm).
- Sensor Shift: Simulates tilt-shift lens behavior. Adjust framing without altering camera position, orientation, or perspective lines.
- Depth of Field & Bokeh: Includes F-stop control, Squeezing Factor (anamorphic lens simulation), and Dynamic Focus Tracking on animated objects/vertices.
2. Color Management
- AgX View Transform: Added AgX View Transform alongside Standard mode for better highlight retention and color fidelity.
- Look Profiles: Includes AgX-exclusive profiles such as “Punchy” and “Greyscale”.
3. Render Settings & Denoise
- Independent Workflows: Separate configuration panels for Preview and Final Render to balance interactive performance and output quality.
- Quality Controls: Adjustable Bounce Counts, Diffuse Bounce Counts, and Brightness Pixel Noise Threshold (firefly reduction).
- Denoise Options: Flexible Viewport Denoise triggers, sample count thresholds, and pass-assisted noise reconstruction (Albedo/Normal).
4. Visual & World Background
- Decoupled Lighting & Background: Independent controls for World Lighting and World Background panels.
- Dynamic Sky System: Procedural atmosphere system with customizable sun brightness, sub-horizon colors, and edge blur controls.
- 2D Background Integration: Unified 2D background management directly within World Background controls.
5. Bloom & Glare
- Multi-Scatter Method: Combines 6 bloom layers for realistic, natural glow without retro/vintage overexposure artifacts.
- Kernel Method: Supports EXR/DDS HDR textures for custom bloom shapes with high-luminance Boost controls.
6. Render Passes
- New Render Passes: Added support for Transmission, Coat, Sheen, Emissive, Specular, and SSS (Subsurface Scattering) passes for enhanced post-compositing workflows.
Have fun exploring the new features, and please keep us updated if you encounter any issues!
