bump strength

For some reason I can't see any effect from the Bump Strength slider in the Surfaces (color) tab. Is there something I need to do to enable it? I tried rendering lit via both the default settings and UberEnvironment. I can see the changes in the thumbnail in front of the slider tab, but changing the slider between 0% and 200% has no effect at all.

    Which surface shader?

    Because, if you are using one of the omnifreaker products (uber, uber2, hss) there is also an on/off switch.

    Also, what are you applying the bump to?

    UV/tiling problems can mess up bump and displacement.

    With Bump or Displacement the sub settings are just as important. The settings of -0.010 and 0.010 are VERY low, I suggest you read the DS3 PDF manual, it gives a very good explanation and those still apply in DS4.5.

    I think sometimes I have to render the scene before I can see the changes too.

    Try a spotlight shining from the side on the object, in some lightsituation bump can be difficult to see.

    Yes, you need to render to see bump and displacement.

    That was it, thanks! adjusting the Negative Bump and Positive Bump sliders did the trick. (sliders "Minimum" and "Maximum" or "Negative" and "Positive" in DS3 manual depending on whether you're looking at the picture or text).

    I didn't even see them, in fact. I normally pose in DAZ Studio and render in Bryce, I'm going to use that as my excuse. :-)
