fclem: Why is this necessary? | |||||
Not Done Inline ActionsIn order for each shader type to have its correct properties from ShaderCreateInfo, the correct info name needs to be passed in. Each of the input vert/geom/frag base sources for each material type (Surface, Volume, World etc and Mesh/Hair/Pointcloud) require a unique create-info. As these were resolved in a separate function, it seemed to make sense to determine the correct associated create info to use in the same place, to reduce code duplication. I had experimented with referencing the vert/geom/frag source file directly inside the create-info, though these caused a few issues, as there are some source modifications when using the DRW_shader_library_create_shader_string path. The relevant descriptions are located alongside the source/info fetching functions: e.g. eevee_get_vert_info. Though please let me know if a different approach is preferable.
