There was a problem hiding this comment.
before this shader was
struct UniformBufferObject {
float a; // abs offset = 0, rel offset = 0, size = 4, padded size = 4 UNUSED
float b; // abs offset = 4, rel offset = 4, size = 4, padded size = 4 UNUSED
float c; // abs offset = 8, rel offset = 8, size = 4, padded size = 8 UNUSED
float d; // abs offset = 16, rel offset = 16, size = 4, padded size = 16 UNUSED
} ubo;
struct UniformBufferObject2 {
float b; // abs offset = 4, rel offset = 4, size = 4, padded size = 4294967292 UNUSED
float a; // abs offset = 0, rel offset = 0, size = 4, padded size = 16 UNUSED
float c; // abs offset = 16, rel offset = 16, size = 4, padded size = 4294967288 UNUSED
float d; // abs offset = 8, rel offset = 8, size = 4, padded size = 8 UNUSED
} ubo2;
but now the bottom one looks like
struct UniformBufferObject2 {
float b; // abs offset = 4, rel offset = 4, size = 4, padded size = 4 UNUSED
float a; // abs offset = 0, rel offset = 0, size = 4, padded size = 4 UNUSED
float c; // abs offset = 16, rel offset = 16, size = 4, padded size = 16 UNUSED
float d; // abs offset = 8, rel offset = 8, size = 4, padded size = 8 UNUSED
} ubo2;
