adding AO node to my material

decorix

Hi All,


I've a material setup which I haven't made my self, but
i would like to build in AO node. The problem is that I don't
realy know how to connect AO node (outlined in green)

The node starts from the Diffuse_base

and then splits up with a Texture_A and A_dirt_on/off which
can be controlled secondly there are parameters for adjusting the
texture coordinates.

The only part I would like build in is an AO part so I that have the option to overlay ao texture in combination with a tilling texture.

Does anybody know how to add this? As I have no more IF slots to
connect my AO.

Thanks, advanced

Create a 2nd UV channel in Max and bake out your AO map. In UDK create a Tex Coord node and set the UV channel to 1 (as opposed to the default of '0' I think.) Plug the Tex Coord into your AO map param node. Multiply your AO Param by the final diffuse input.

Hello praetus,

Thanks for replying.
Can you perhaps show me ? (attachement jpg? I only don't understand the last bit you mention "Multiply your AO Param by the final diffuse input"

He just means use a multiply node with the 2 inputs being your AO map and your diffuse base.
