C Specification
The possible values returned by the implementation when the vertex shader reads an unbound vertex attribute are:
// Provided by VK_KHR_maintenance9
typedef enum VkDefaultVertexAttributeValueKHR {
VK_DEFAULT_VERTEX_ATTRIBUTE_VALUE_ZERO_ZERO_ZERO_ZERO_KHR = 0,
VK_DEFAULT_VERTEX_ATTRIBUTE_VALUE_ZERO_ZERO_ZERO_ONE_KHR = 1,
} VkDefaultVertexAttributeValueKHR;Description
-
VK_DEFAULT_VERTEX_ATTRIBUTE_VALUE_ZERO_ZERO_ZERO_ZERO_KHR - the value read for an unbound vertex attribute is (0,0,0,0).
-
VK_DEFAULT_VERTEX_ATTRIBUTE_VALUE_ZERO_ZERO_ZERO_ONE_KHR - the value read for an unbound vertex attribute is (0,0,0,1).
