Seperate UV Island in 2nd Map channel how?
polycounter lvl 10
Hello there,
I have my object mapped in Channel 1 for diffuse and normal. There are seams everywhere. I want to select the polygons around the seam and re-map ONLY those polygons on Channel 2. This way I can erase the seam in PS.
So my stack looks like this.
UVW map 2 - the map sees only the polys I have selected below)
Edit poly ( I have the specific polys selected in sub object here)
UVW Map 1 everything is mapped here typically
Edit Poly (no sub-object selections)
So its semi-working how I want however I do not have access to the UVW map Channel 2 plannar mapping tools. I can hit the "edit" button and see my UV island and that only the polys I selected in the "edit Poly" modifier below are present, however I cant map them.
Im sure you have seen that when you forget you are in sub-object and you throw a UVW map on top of that edit poly sub-object the options are grey'd out. Ive done it by accident a bunch, but now I am doing it on purpose and was wondering how I can get by this roadblock.
I guess the short question is this. How do I take a specific selection of polys from an entirely mapped object and single out those polys to be mapped on another channel without bringing the rest of the UV's from same object with me into channel 2?
Thanks!

The stack goes like this for those also confused
UVW Mapping modifier - change to channel 2 and make Planar map ect ect.
Unwrap UVW - not much can be done here - but change to channel 2
Edit Poly - sub-object selections for map 2 here
Unwrap UVW - map channel 1
Edit Poly - no sub-object selections
sorry for the false start on this thread....
micron fail.
anyone here eliminate seams this way?
once you've painted out the seams you can apply the new texture to just those polies that you're working with, then in the RTT window bake out to channel 1 for your final texture.
you can work this way with a single UVW modifier.
edit: come to think of it. maybe just look here
I found this tutorial: Cornerofthedreamingmonkey
Its actually much better than that Gamasutra tutorial you mention.
I was actually working directly off that Gamasutra tut... the author is not doing it the same way as you mention tho. Course it was written in 2006 so that might be why there is a problem, perhaps max has changed, or maybe its just my pea sized brain.
either way i finally got it, thanks for your response!
