Why Cloud texture has square cell pattern?

Question

When I am using Cloud texture as bump map in Blender Render, this cells appear. How can I make them go away?

Answer 1

You might consider settings like this.

Influence [Color] and No influence [Normal]

It is not clear that the User can use all clouds as a Normal Map. Normal Map and Bump Map are different.

Any one can paint a bump map manually. That is not true of Normal map. Normal Maps can baked.

You may also want to see the Displacement Modifier which uses textures.

Short answer, rather than a complete technical answer.
