Compiling Shaders about bgfx HOT 3 CLOSED

Yes GLSL is text in .bin file, but technically they should be considered binary (they are only in source form because that's how GL expect it, if I could use binaries there I would :). Source GLSL shader passes throught GLSL optimizer and it outputs optimized version of GLSL. HLSL has binary representation. The reason why I don't pass HLSL source is because I don't want to link or dynamically load D3DX DLL. You should be able to pass different vertex attributes to shaders, even if they mismatch shader inputs.

As for multiple render targets, I'm planning to add them, but I want solution that would work for GLES2, so that part is a bit more difficult. Anyhow it's on my todo list to be done soon.

okay, makes sense somehow :) It also wouldn't be very clever to optimise something still with compile switches... perhaps I have to think more about a shader configuration (a json file with all possible define combinations that are allowed on a shader and the compiler compiles all combinations). but that would be something for a upper software layer, not for bgfx itself...

Yeah idea is to keep those shader code generators in layer above bgfx. shaderc is running full preprocessor, so if you can achieve what you need with some preprocessor magic, you could do it with shaderc. Also you could generate multiple .sc files in some scripting language, and then run it through shaderc to get final binaries. If you share small example on Gist I might have better idea what you're trying to achieve and I might have solution for it.
