This PR adds two new pieces to the correctness checking within MaterialX, these were discovered while doing work on MaterialX library files. I found them helpful, so I thought it...
Working towards building Frameworks for macOS and IOS, this PR adds the option to build MaterialX as a single monolithic library. CMake aliases are exported for the standard library targets...
This is a follow on from the previous draft PR #1684 on implementing structs. This implementation maintains the structs in the shader code. This is still very much a draft...
This is a first pass at updating the specification to reflect the upcoming struct support in PR #1831. A lot of this is lifted from the old 1.38 specification pdf,...
