v1.3.7

SDK

• Bug Fixes
  • Fixes issue in ReductionCS.hlsl that caused a divide by zero when all probes in a volume are disabled. A reduction thread should not contribute to the variability calculation if threadFootprintWeightSum is zero.
  • Fixes issue in ProbeBlendingCS.hlsl that prevented probeBrightnessThreshold from working as intended. Fixes GitHub Issue #70.

Test Harness

• Improvements
  • Enhances shader compilation options and allows for the options to be specified in *.ini files.
  • Enhancements to frame queueing/buffering. The CPU can now run ahead one frame, allowing CPU and GPU work to overlap.
  • Adds a toggle to enable/disable progressive rendering in the path tracer.
  • Increased the granularity of CPU timestamps and reworks the detailed performance UI.
• Bug Fixes
  • Fixes minor issues with Vulkan timestamps.
