What is the color of a normal map?

A normal map is an RGB texture, where each pixel represents the difference in direction the surface should appear to be facing, relative to its un-modified surface normal. These textures tend to have a bluey-purple tinge, because of the way the vector is stored in the RGB values.

Are normal maps linear or sRGB?

Albedo, metallic, specular and occlusion are sRGB. Normals and smoothness are linear.

What is the neutral normal map color?

At any point we should have the normal always pointing in the Z (blue direction) with no X (red direction) or Y (green direction). Thus the normal map (since it is a “normal map”) should have the colour of the normals which is just blue (R = x = 0, G = y = 0, B = z = 1) with no shades in between.

How do I make a normal map?

Create the Normal Map

  1. Open texture in Photoshop as you would normally any image. Make sure the image mode is set to RGB.
  2. Choose Filter → 3D → Generate Normal Map…
  3. Adjust your map as necessary (I left my to default). Click OK.
  4. Save your file as PNG (not sure if it really matters). You’re done!

Should normal maps be sRGB?

Normal maps need to be linear space, so sRGB (gamma space) should always be turned off.

Is normal map sRGB or raw?

Normal map appears with seams or with incorrect lighting This is, by default, sRGB. You can set the Color Space to Raw for each normal map in its respective File Attribute Editor.

What is a normal in 3D graphics?

A normal in 3D modeling is a depiction of the orientation of a polygon’s surface. It’s basically a perpendicular line jutting out from the plane. When you’re dealing with a curve, you’ll use the plane lying tangent to the point in question to find its normal.

What is AO map?

An Ambient Occlusion or AO map is a grayscale map which contains lighting data. It is not typically used as its own map, and is instead usually combined with the diffuse map to bake in soft shadows.

What makes a good normal map?

There are three key components that you must nurture in order to bake perfect normal maps: Smoothing Groups, UVs and the Projection Cage. Mistreating any one of these components can lead to ugly, normal maps and wasted time.
