Thanks.

Hello,
I have this validation error multiple times (one per BLAS or TLAS I think) when I execute BVHBuildTask.
I tried to set this buffer usage flag to all my buffers so I don't think it's coming from my implementation or I forgot to set up a feature?

EDIT: I created a minimal main to reproduce.

Vulkan SDK: 1.3.224.1
KickstartRT: v1.0.0 (VULKAN)

This issue represents a few quality of life improvements around meshes that we have planned for the 1.0 release.

Specifically it includes

1. Allow unregister instances from TLAS to temporally hide and exempt from TLAS with keeping the instance with its direct lighting cache.
2. Support multiple geometries per instance
3. Improve tile-cache continuity during LOD switching

Please let us know any comments on these features!

Under Build Steps, for both Windows and Linux, it has in the git command "–recursive" when it should have two dashes: "-–recursive".

This issue represents a few new features that will help users get better performance from the Kickstart RT SDK.

Specifically it includes:

1. Support for global ray shortening
2. Support for multi-resolution light injection

Please include as many details about the problem you encountered or the feature you would like implemented.

For bugs:

• The platform and/or operating environment
• Any relevant hardware and driver information (GPU, etc).
• Screenshots showing the bugs or artifacts (if applicable).

We'll evaluate and post comments here!

Release 1.0 will be the final stable release unless we encounter bugs or feature requests. So please do file them if you desire. We cannot guarantee to implement new features, but will consider. All bugs will be addressed as best as we can.

Thanks for your input!

It's great that this is MIT licensed, but the RayTracingDenoiser dependency is still under standard GameWorks License.

Can we get RayTracingDenoiser MIT licensed?
