Capability Geometry allows to use the Layer builtin in geometry and pixel shaders. For vertex and domain shaders ShaderLayer should be used, but it's only available starting from SPIR-V 1.5. ShaderViewportIndexLayerEXT can be used instead with extension SPV_EXT_shader_viewport_index_layer. --- include/vkd3d_shader.h | 2 ++ libs/vkd3d-shader/spirv.c | 28 +++++++++++++++++++++++++++- libs/vkd3d/device.c | 9 +++++++-- libs/vkd3d/vkd3d_private.h | 3 ++- 4 files changed, 38 insertions(+), 4 deletions(-)
