material editor: mix >add? > 0-1+ range

[Dave Black]

Not sure I understand the problem fully, but let me just say this:

First, you can't add 2 maps together and have them BOTH be at 100% visibility. If you have a mix map, a value of 50 is as high as you can go. Any higher is going to give you more or less of the 2 maps.

If you want to have both maps together at 100% visability, you'd have to defy the laws of physics. 2 objects cannot exist in the same place at the same time.

What you are asking is impossible. Not just in max, but even in reality. Try using a mask, or play with the values in PS.

I could be reading your question wrong, and if I did, I apologize.

Hope that's of some help.

laws of physics... ha, yes but this is not the real world. If you are talking about difuse mapping you may have a point (but it is debatable, look into hdri) but bump mapping?...
Your answer means max cannot do it? Other programs can.

What i do not want is to have the program range clip my bump.

Here is the example
.one bitmap bump map, with some areas full white.
.one noise bumpmap

what i want is that the noise bump map acts uniformly ON TOP of the bitmap bump map. This means, even if i have a full white feature in my bitmap I want the noise bumpmap to affect it. The mix material masks the noise where it intersects the higher ranges of the bitmap. There is no logical reason why this should necessarily happen.

Have you heard of hdr? In reality images have a range of more that 1 - 0, i want something akin to this for bump mapping. Is it not possible?!!!

mh not sure if this is possible...

you probably just want to know if it's possible in max, but there sure is another solution to this

just turn down the maximum brightness of your base map to 50% of it's original value, then mix in your noise

THEN increase the RGB value (or bump amount for that matter) of this mix material

this, in a sense, will give the highlights of the map a >1 scalar value

of course! thank you

anytime

From what i get you want Additive blending.(Colorcomponent1+Colorcomponent2). Check this thread and the Peter Watje plugin
