Your level should not throw errors if your shader is not supported by the engine. You can check if it is PRO or below and use other materials as fallback.
You can use shaders at your own risk and make sure you have solid fallbacks just in case the jury has other hardware than you.

If your mdl files support normal maps,... it is great. But they should look good without shaders, too.
