Thanks to the workaround in obs::tools, gfx::shader::shader now supports dynamically rebuilding the properties with new properties without crashing OBS Studio. This effectively allows you to have an up to date view of the current parameters for the shader technique. Additionally with file watching, live development of shaders is possible at very little cost. Currently only file times and size is looked at every 333ms, but in the future it is possible to also watch for file renames and more.
