And when do i use each or both?

Hello! I’d say bump only uses the z axis to compute the surface shading, hence you only need grayscale images for it to work. It’s a cheap technique and the results are not very accurate in close ups. Normal maps encode the surface shading using three axes XYZ represented by rgb colors, so it can c…

so normal map is always preferred? even for procedural?

I’d say use a normal map if you have a normal map. If you don’t, use a bump map. Example: I take a photo of a brick wall. In my image editor, I create my own greyscale image of it and tweak it to create a bump map. I have no easy way to create a normal map from it. A bump map will do. It will look f…

Hey @BaidDSB , As mentioned by @Strangerman , Bump maps are GreyScale, so they can only represent a single offset direction, which in turn dictates how the light should behave when it is hit. Normal maps on the other hand give angular direction and this provides the lighting with a more naturalistic …

Hi there, Blender’s own documentation is usually helpful, also in this case: https://docs.blender.org/manual/en/2.79/render/blender_render/textures/properties/influence/bump_normal.html Quotes below are from there. Long story short, bump maps are BW images, that tell the surface, how up (or down…

@AgentTuron @DamianJ @KotlinBear Alright. what about procedural textures? If i create something from a wave/noise texture etc, i probably wont have a normal map. In that case is there a difference between Normal and Bump node?

Hi there, Depends on the workflow. But Bump should be fine. I would say, you use a Bump node or more. You don’t need to combine the BW maps beforehand, only if they thematically match. Usually the largest-deepest is first. Texture into Height, then you add another bump if needed, after that. Previ…

Whats the difference between the Bump and the Normal Map Node?
