Chaos has released Corona Renderer 11 Hotfix 2 for 3ds Max, an essential stability update that expands compatibility and resolves critical technical issues for users working with 3ds Max versions 2016 through 2025. While the initial Corona 11 release introduced major workflow enhancements like the Corona Tile Map and Scatter Altitude, this hotfix focuses on ensuring a seamless experience in the newest software environments. Key Updates in Hotfix 2

The primary goal of this update is to address bugs that could cause render failures or system instability.

Autodesk 3ds Max 2025 Support: This hotfix officially brings compatibility for 3ds Max 2025, ensuring that the renderer functions correctly within the latest iteration of the host software. Color Management Improvements: Corona Renderer 11 Hotfix 2 for 3DS MAX 2016-20...

The Gamma Correction operator, which was added in the previous hotfix, has been removed. Corona now automatically applies the necessary correction based on your 3ds Max color management settings.

An improvement includes a new warning for users if Corona does not fully support their current OCIO color management workflow.

Caustics and VFB Stability: The update fixes rare "NAN" (Not a Number) errors in both the Caustics solver and the Virtual Frame Buffer (VFB), which previously caused renders to fail or display incorrect black/white pixels. Chaos Scatter Optimization:

Resolved an issue where certain scenes containing Chaos Scatter might never finish loading.

Fixed a bug where using the "Isolate" tool would force Scatter to recompute, which significantly slowed down viewport interactions.

Addressed incorrect edge trimming for hierarchical and group models, ensuring that instances are clipped accurately along boundaries. Core Features of Corona 11

Hotfix 2 maintains all the powerful procedural and performance tools introduced in the main Corona 11 release: It looks like you’re referencing a software release:

Corona Tile Map: A procedural tool for creating complex patterns for bathrooms, kitchens, and floors without relying on external bitmaps.

Scatter Altitude and Look At: New controls for Chaos Scatter that allow you to define height limits for vegetation (e.g., treelines on mountains) and orient scattered objects toward a specific target.

Edge Map: Simplifies the process of adding weathering, staining, or "worn-out" effects to the edges of objects.

Intel Denoiser: Now supports both CPU and GPU denoising, removing the strict requirement for NVIDIA hardware to achieve clean renders quickly. Installation and Download

Users with an active subscription can update through the Corona Download Page. It is recommended to uninstall previous versions of Corona before running the new executable to prevent installation conflicts. For those using the standard material library, note that the additional 5.2 GB download may be required upon first installation. Corona 11 (Hotfix 2) released for 3ds Max
