Normal maps causing colour changes to diffuse !

[stevesideas]

I have a map in the diffuse slot. Ive exported a normal map from crazy bump into the vraynormalmap in the bump slot. If I set the bump to 30 there is significant change to the diffuse colour...if I knock it down too much the normal bump isnt apparent in the render at all..what am i doing wrong or is this a bug ?

I would actually like to set the bump amount to something like 50 so that it is more noticable but this alters the diffuse colour even more !

Im not sure what has been happening recently but it seems to be working now. Not changed anything.

The number one cause of this problem that I have seen is normal maps that have been accidentally gamma corrected. Watch out for that.

That's one thing I didn't take into consideration...cheers for the pointer.
