I want to create an empty normal map , how do i do it ? The reason is because i want to paint multiple other normal map into the empty normal map .

I don't really understand how normal map works so i don't have any idea on how to create empty normal map.

Head over to the Texture Paint workspace, click the little plus sign + in the Draw properties on the right side (Properties Editor) and select Normal:

enter image description here

This way the new normal map also gets connected to the shader, automatically. The suggested RGB values are 0.5, 0.5, 1.0, 1.0 or #8080FF.

  • $\begingroup$ @user6668201 I don't have access to 2.79 anymore. I guess this was introduced as of 2.8x $\endgroup$

  • $\begingroup$ ah its okay , i'm not in any way forcing you to answer , i still can just wait for other people and use my method in the meanwhile $\endgroup$ Jul 18, 2021 at 16:24

Nevermind i found the answer
Turns out normal map default color is RGB(128,128,255) , but blender is using 0-1 scale for rgb so converting from scale 0-255 produce some decimal inaccuracy , instead use the hex value for RGB(128,128,255) which is #8080FF

All i need to do is to put the default color value to the color when creating new image enter image description here

    $\begingroup$ There is an built-in way: Head over to the texture paint workspace, click the little plus sign in the draw properties on the right side and select "Normal". $\endgroup$

  • $\begingroup$ oh really ? can you just answer it instead of in this comment ? if there is really built in way to do it then it is a better method since there is no inaccuracy due to conversion $\endgroup$ Jul 18, 2021 at 15:52
