# VkClusterAccelerationStructureClusterFlagBitsNV(3) Manual Page

## Name

VkClusterAccelerationStructureClusterFlagBitsNV - Bitmask specifying cluster acceleration structure flags

## C Specification

Bits which can be set in VkClusterAccelerationStructureBuildTriangleClusterInfoNV::`clusterFlags`, specifying flags for clusters in an acceleration structure, are:

    // Provided by VK_NV_cluster_acceleration_structure
    typedef enum VkClusterAccelerationStructureClusterFlagBitsNV {
        VK_CLUSTER_ACCELERATION_STRUCTURE_CLUSTER_ALLOW_DISABLE_OPACITY_MICROMAPS_NV = 0x00000001,
    } VkClusterAccelerationStructureClusterFlagBitsNV;

## Description

- VK_CLUSTER_ACCELERATION_STRUCTURE_CLUSTER_ALLOW_DISABLE_OPACITY_MICROMAPS_NV specifies that the specified cluster acceleration structure may be referenced in an instance with VK_GEOMETRY_INSTANCE_DISABLE_OPACITY_MICROMAPS_BIT_EXT set.
