# Effect and semantic

## Recommended Posts

If in a effect file, is it possible to have 2 variables with the same semantic? For e.g.
float4x4 MatrixA : WORLD;
float4x4 MatrixB : WORLD;

If it is possible, if I am to call GetParameterBySemantic(), which parameter will it return? Thanks

Yeah, you could do that.

Keep in mind, however, this isn't very practical (or at least I can find a use for it).

Hope this helps.
