[SPIR-V]

Description
No matter what i do, i can not bind my bindless resource to other descriptor set. it always 0.

Steps to Reproduce
[[vk::binding(0, 1)]] Texture2D BindlessTextures[];
[[vk::binding(1, 1)]] ByteAddressBuffer BindlessBuffers[] ;

or this:

Texture2D BindlessTextures[] : register(t0, space1);
ByteAddressBuffer BindlessBuffers[] : register(t1, space1);

the output after compilation:

UniformConstant type.2d.image[]* BindlessTextures : [[DescriptorSet(0), Binding(1), UserTypeGOOGLE]];
StorageBuffer type.ByteAddressBuffer[]* BindlessBuffers : [[DescriptorSet(0), Binding(5), UserTypeGOOGLE]];

-> DescriptorSet(0)

i do not care about bind-index, but i want to have bindless resources in separate descriptor set.

Environment

• DXC version 1.9
• Host Operating System Windows

my compiler flags are:

-Wno-effects-syntax
-Wno-unused-parameter
-spirv
-fspv-reflect
-fspv-target-env=vulkan1.3
-Zsb
-HV 2021

-T 6.6
-fspv-extension=SPV_EXT_descriptor_indexing
-fspv-extension=SPV_EXT_mesh_shader
-fspv-extension=SPV_GOOGLE_hlsl_functionality1
-fspv-extension=SPV_GOOGLE_user_type
-fspv-extension=SPV_KHR_ray_query
-fspv-extension=SPV_KHR_physical_storage_buffer
-Zpr

any help would be appriciated.
thanks,

spvReflectCreateShaderModule shows DestritorSet IS 1 as acpected.
it must be the RenderDoc issue showing UniformConstant type.2d.image[]* BindlessTextures : [[DescriptorSet(0), Binding(1), UserTypeGOOGLE]];

the second issue was with ByteAddressBuffer.Load always returns zero indices for vertices...
Replacing with vk::RawBufferLoad fixed all issues.
