Bump strenght - I'm missing something super-obvious! Tweet

[ThomasVandenAbeele]

Hi,

I'm making some cardboard boxes, super-simple stuff. But I can't seem to figure out how to reduce the bump strength of the procedural bump texture I have!

How do I do this? I have a noise texture feeding into the bump channel, all working well, but contrary to my expectations, neither contrast nor gamma seem to have any effect on the bump texture.

All help greatly appreciated, as I'm sure I'm missing out on something very, very basic!

Thanks!
Thomas

Maybe use Turbulence procedural. It has at least Power-attribute.

If it is a real subtle bump you are after like on cardboard box etc, you will want a Power value of something like 0.04, and maybe even way less...

The problem is probably that Noise Procedural does not have Power value...

Run it through a colour correct node and use the brightness to control the strength?

Turbulence should give you the effect you want.. you just need to scale it way the hell down.. like 3%-5% or so, for cardboard etc, with a very low power.
