◆ CreateCompactedBuffers()

ResultCode AZ::RHI::RayTracingBlas::CreateCompactedBuffers ( MultiDevice::DeviceMask  deviceMask,
const RayTracingBlas &  sourceBlas,
const AZStd::unordered_map< int, uint64_t > &  compactedSizes,
const RayTracingBufferPools &  rayTracingBufferPools 
)

Creates the internal BLAS buffers for the compacted version of the sourceBlas The compactedBufferSizes can be queried using a RayTracingCompactionQuery
