--The attack of the gamma correct utility--
Thank you very much for pushing me to learn linear workflow.
I have used the gamma correct utility in the procedural textures and another way to fix the gamma issue for the file texture of the floor.
The other way is the EXR file format that works with floating point information (I dont know what im saying but looks cool), and you dont have to gamma correct anything because there is no change of color space when the picture is displayed in the motitor that works in srgb color space.
So by using exr textures (you convert them with photoshop) you save the transition from linear (what maya use) to srgb (what the monitor use)
And here is the result. Im not sure if i like this render more but suposedly it is more correct if everything is ok.
note: To convert a picture to the exr format, first it has to be changed to 32 bit mode or else the exr option will not appear in the "save as" menu of photoshop.
