Prerelease: no

Release notes: ABI compatible with the MDL SDK 2025.0.5 (387700.3418) binary release (see https://developer.nvidia.com/mdl-sdk)

Added and Changed Features

• General
• The recommended vcpkg version has been updated to git ID 5fac54d. This update includes Boost

1.90.0, Vulkan SDK 1.4.328.0, and various security fixes for dependencies.

• Added new API component IScheduling_configuration, mostly to control load limits when using

the CPU baker.

• MDL Compiler and Backends
• Added a simple cache that reduces calls to the (potentially slow) entity resolver.

• MDL SDK examples
• Example df_vulkan:
• Added a --noaux option to avoid code generation, execution, and export

operation for the auxiliary buffers.

• Example DXR
• Use D3D12 shader collections to improve compile time performance.

Fixed Bugs

• General
• Fixed hair BSDF code not callable for native backend. The Target_code::execute_bsdf_*

functions can now also be used for hair BSDFs.

• Fixed rare cases where the module builder computed a too low minimal MDL version.

• MDL Compiler and Backends
• Fixed missing adapt_normal function pointer in Texture_handler_vtable.
• Fixed some error messages reference wrong source code locations.
• Do not fold casts of +/-inf and NaN to int`. Create an error when used inside a const

expression.

• Fixed a crash in the native backend under Windows that is caused by function with big stack

frames because the __chkstk symbol was missing.

• Fixed a crash when optimizing clamp(x, min, min) if typeof(x) != typeof(min).

• MDL Core examples
• Example df_vulkan:
• Fixed validation errors regarding semaphore reuse.

• MDL SDK examples
• Examples Shared:
• Improved parameter editor to better support long parameter names.

• Example DXR and df_vulkan:
• Fixed translation of the targeted MDL version based on the MaterialX version.

• Example df_vulkan:
• Fixed install target for MaterialX content.
• Fixed detection of MaterialX content when the vcpkg layout is used.
• Dump MDL content generated from MaterialX input before attempting to load it.
• Fixed rendering artefacts for materials with volumes.
• Fixed validation errors regarding semaphore reuse.

• Example DXR:
• Use D3D12 shader collections to improve compile time performance.
• Filtered non-float vertex data from glTF models as those are not supported at this point.
