Texture color in Patch Image Method

[Pitcher]

For whatever reason, the program had the cobblestone pattern going one way to the left of the canal that the Bridge of Sighs spans and another way on the right side. I could not rotate the pattern to the right until I split it off from the one on the left and rotated it. I gave both the same properties, but for whatever reason the texture on the left ends up much darker than the pattern on the right. I am using Version 18 of A:M. I am also interested in knowing if there is a control for darkness of a texture and where that control is. Here is the example I am describing:

You're sure the surface properties of both those sections are the same?

And neither one has some other material still on it from some previous experiment?

Normals are facing the same way?

All settings are the same. I'll check Normals again. Thank you both.

Fuchur, you know my failings. Good guess! (I have never found any use for flipping normals until we did the 3-D printing. My pictures all worked. Apparently, normals are a key to textures, 3-D printing, and who knows what all? I wish the normals were all born pointing the right way. It takes a lot of time to flip normals. I think the count on the picture above is over a million patches.) Thanks!

 

Is there some control that can lighten or darken the images used in texturing?
