I can see bumps on alpha mask render, is that wanted ?
Or did I set the bumps too high on negative values ?

The range depends on your settings....
You have the A, B and C value.... ignore A for the moment. Search in the forums for more details - already was asked thousands of times before
Basically, C is your blackpoint and B your Whitepoint. - I think, it's translated to meters which is why the values have to be that low to look right...
If you set a negative B, white suddenly makes holes instead of bumps.
A C-value of exactly 0 would tell Indigo that the lowest colour is black (except, as I said, if your B is negative. Then, black will form bumps instead of holed)
If you want to have 50%-grey in the middle... I think, you would have to set the C-value to the same as the B-value but inverted...
to answer your questions more directly: On default, black=0 and white=1. Grey would be 0.5
To set white=-1, black=1 and grey=0, you should set B to -*yourBumpValue* and C to *yourBumpValue*
Bumpmapping hasn't got anything to do with world scale, I think.... Except the values really are meters.........

bah, i guess this is an exporter question, but would it be possible to put in a material override toggle? say if i get the sudden urge to render my whole model with a pink glass material. what i really mean is for clay renderings and such.
by the way, havent thanked you, ono, for the alpha rendering. definitely a TON easier to composite stuff now! i find that the lens matching between Blender and Indigo isnt perfect (somethings off...) so it saves a lot of time scaling and distorting a mask i make in Blender to fit the Indigo rendering!
cool.
