Understanding Poser bump settings to better convert to Studio
I am working on setting up an old environment prop that was built for Poser in Studio, which includes no Studio material presets. I don't own Poser, so I can't load this into Poser to examine the settings in Poser. When this prop's .pp2 files are loaded, the only thing loaded are the diffuse textures. The 'legacy compatibility' section of the material definition in the .pp2 doesn't reference the bump maps. However, the shader tree nodes do list the bump map info.
I've gone through and manually loaded the bump and spec maps into the appropriate slots. But now I need to manually configure the min/max bump values. I'm hoping someone can give me insight into what the three parameters of the bump value in a Poser shader tree node mean in Poser so I have a starting point on converting them to Studio.
The value entry for the Bump node of the jukebox in this prop is ".1 0 10", for example. I'm guessing the three values map to "strength min max", but with some decimal places shifted around. If so, I'm assuming the strength of .1 would translate to 100% in Studio, given I've seen other Poser stuff with .0xx values in this field. But what about the min and max values, assuming that's what they really are? What units are these in?
