Good thing I was looking at older posts, this tutorial could have just vanished which would of been tragic. It looks like a greatly well explained tutorial covering a subject that is rarely covered.

You even provide a zip...

Yes it does, just insert the light map in the material's ambient or self-illumination slot, and select "map channel 2". Bingo.

(if you put it in the ambient slot, I believe you have to set the scene's ambient to "1" in the environment settings)

Jussing - I were trying what you said me but , trully I cannot do this. Or I making something wrong, or You arn't catch the idea what I were trying to say (I'm not good at english so maybe why). Max can't add together this channels and textures, they arn't blending. The soft shadows don't shown at the object with first channel and main texture. Maybe I cannot say that I know that and think of that. The final effect should be like multiply in shop.
I'm useless ...

Yes, I think I'm understanding you, you can have Max show a combination of both maps, like a multiply in Photoshop.

a) add your texture map in "diffuse" slot, use UVW map channel #1
b) add your light map in "self illumination" slot, use UVW map channel #2
c) turn off all light in the scene
d) render, and see your soft shadows from the light map affect the texture map

Cheers,

(note: the "correct" way is to use ambient slot and not self illumination, but I prefer the latter, cause then I won't have to tamper with the scene's ambient settings)

EDIT: however, this of course only works in render, not in the viewport... maybe that's what you mean...

Thanks for the tip jussing, I try what You said and its really works, Unfortunatelly this soft shadows don't looks good, the are almost invisible on the object with no texture (white diffuse) and when I turn on the texture on diffuse channel they are almost invisible. Anyway thanks for this tip, if I had a while I'll correct the tutor.
Cheers

Hmm, I don't understand why they are almost invisible... Try posting screenshots.

Did you turn off all light in the scene?

Cheers,
