vray and final render problem

hello all, i am new here and i am seeking help with a problem that i have encountered.
i am trying to obtain a final render of a scene that i made from saved irradiance and light cache maps following a tutorial link that was made for making animation still frames.
what i am trying to obtain is saving the light cache maps from a lower resolution, then produce the final render in a higher resolution.

my problem is when i try to render the final image, the image has changed its original colors. for example white walls are now blue.
what confuses me is once when i tried this method, it actually worked without any problems, but now as i said i changes the color of the final image.

if i missed out any details that you may need please tell me.

it seems colors that appear are the raw red green and blues
