The problem I have is that I can't get my head around the 32 IEEE values thing. and the floatV and floatr aren't helping me...any ideas?.... Thanks a lot.

I don' know what the reason can be for this. Anyone can tell me what is the right way to use a variable from a script in a shader? Is the only way through floatV or floatR? Thanks a lot.
