How do I overlap texture maps?

[Stuh505]

How can I assign multiple maps to the same object which can overlap, with separate adjustable UVW gizmos?

Using multi-sub object, I can assign multiple maps with separate adjustable gizmos...but they CANT be overlapping this way.

Try using two material channels, I'm not 100% sure but i think that this will help you out.
Thats if you are using max though cos i don't know about other software at all.

[Stuh505]

Yeah, using max.

I don't understand what you're suggesting.

I still can only assign 1 overral map to a certain material ID of an object...how could I have the sub-maps be using different gizmos?

[Stuh505]

Could you (or someone else) explain how material channels work? I don't really get it.

I assigned 2 UVW Maps to an object, and set them to operate on material channels 1 and 2 respectively.

Then I assigned a material to the object, and for the diffuse map under coordinates I chose material channel 1, hoping that this would make it be aligned via the UVW Map set to channel 1....but instead, the map just doesn't appear at all.

I'm not 100% sure myself, just something i was playing around with the other day to try and find out how they work.
I was trying to put an extra uvw's on the model for specific use for dirt maps.
If i have any luck i'll let you know how i managed it.

Have a look at this site. Several good explinations on many topics.
NeilBlevins (http://www.neilblevins.com/)

He has a tutorial on mapping as well. :)

Hope it helps. :)

His example is tailored to a tree, which is great, because I've been meaning to figure out how to texture my xfrog trees well.

But on closer inspection, it doesn't look like a very practical approach. I understand the need for new UVW coordinates for each branch of the tree, but having to draw overlapping blend masks? This would be nearly impossible to keep track of with hundreds+ of branches.

He doesn't go into an exlpanation of how to use multi-channel mapping, he assumes that is already known in his example.

Funny thing is, this afternoon I got the multi-channel mapping to work (exactly as I was doing it earlier this morning). But then I tried it on a different model and it didn't work! Argh!

But thanks for the site H20, I'll keep checking it out even if it doesn't solve this particular problem.

found out how it works (ive been trying it aswell), these images should help :) really simple example! to test theory

and resulting render (doesnt show correctly in viewport unforunately- may be my settings)

I have the answer you need:
