Release v1.7.0.0

What's new

Features

• Improved Rocky9 and MacOS build instructions and CMake presets for hdMoonray in Houdini
• XPU mode now accelerates both regular rays and occlusion rays for NVIDIA GPUs
• XPU mode now supports more than two (up to 16) motion blur steps/samples for meshes
• Adds FOV controls to spherical camera to allow rendering onto a partial sphere
• Improvements to rdla_filter - splits long lines
• Adds -threads option to moonray_bake
• Makes all parameters (except clamp values) of RemapMap bindable
• Adds a "ramp_input_scale" parameter for diffuse to the DwaBase material
• Adds a PortalLight
• Supports distant lights referenced by a PortalLight
• IntensityLightFilter can now distinguish between direct/indirect paths
• Offset and scale are now bindable for UVTransformMap
• Supports indirect illumination on volumes
• Adds scene variable "slerp_xforms" which fixes scaling when camera shutter is outside motion steps range
• Improved ray-sphere intersection precision
• Avoids BVH rebuilds if geometry hasn't changed in update
• Adds support for min_shadow_distance
• Adds stochastic presence optimization
• Adds Cryptomatte support to hdMoonRay
• Adds reflected cryptomatte data support
• Adds screen space radius controls for curves and points
• Adds support for "primary aov", allow users to specify an aov as the "primary" output
• Includes light filter luminance in the visibility aov
• render_profile_viewer now uses OpenImageIO to display test result images
• Added new guide for understanding shadow ray manipulation attributes
• Shared memory framebuffer interface for sending framebuffer data between processes
• New commandline tool: shmFbTool: test and analyze shared memory framebuffer data
• New commandline tool: shmFbDump: example code to access shared memory framebuffer without using OpenMoonRay lib
