Hi, is there any poser-friendly tool  that would take a mesh and create new UV's and texture maps for the .obj so that the UV's do not overlap and there is only one texture map? E.g. to merge 4 2k x 2k maps into a single 4k x 4k map? Thanks :)

Poser friendly means the resulting .obj is still usable for the .cr2

Four (simple, single color) maps, each taking a separate quarter in the UV map. Each size is 0.5,0.5 (as a UV map is 0..1 in either direction) and the respective offsets are (0.0,0.0) (0.5,0.0) (0.0,0.5) and (0.5,0.5)

Set background to black, mode to non-tiling. 

Ha, that is an ingenious solution aRtBee!

This appears to be the exact opposite effect from what colorcurvature is asking about (no offense - it is a damn cool trick!)

What colorcurvature is looking for is a way to, for example, combine a character's head, body, limbs and inner mouth map into a single imagemap (the easy part), and then also have a new OBJ created that accepts this new map (the hard part).

Just as I was typing the above, I realized that the "hard part" is not really necessary, because Poser can scale and offset textures in the Material Room.

On your Color_Map nodes, set U_Scale and V_Scale to 2. To use each section, set the U_Offset and V_Offset to the following values:

Upper Left: U 0, V 1
Upper Right: U 1, V 1
Lower Left: U 0, V 0
Lower Right: U 1, V 0

No OBJ remapping needed :)

BTW, just in case it's needed: almost any image editor can combine 4 images and save that as a new image; I would recommend GIMP or Paint.net. It's then only a matter of creating an image that is twice the width and height of your source images, and dragging one image into each corner of the new one.

R-Hatch: you're right, I suggested how to combine multiple maps for one object - element. When the OP wants the opposite: a single map for multiple object-elements, then the solution should be the opposite as well. Which is exactly what you're suggesting, your scaling with 2 is the oppositie of my scaling with 0.5, etcetera. Great! And again, no remapping required.

I made a python script to merge the different texture maps into one and offset the UVs in the .obj  of the different matzones accordingly. Didn't have time to verify if it works in Poser yet, however ;)

I hope the single-map-mode makes life easier when modifying the figure in external applications like zbrush. If successful I'll post the script

Y'all are smart.  I'd have never thought of this.

I have a python script which does this - and it works well, although you need to manually merge the diffuse, bump and specular texturemaps into one using Gimp, Photoshop etc.  The python script just re-UV's the figure.  It only works for Roxie or Antonia, but if you know python you would be able to modify it for V4.  It also merges all the head and body materials into one.  I can post if here if you like, but it's uncommented, unsupported code, so you'll need to know python to make any changes.

I originally wrote it so that I could subd figures and then edit the mesh for just the skin material in ZBrush.

I'll think about it :) I'm so short on time currently ;(

But thanks for the offer.

Btw, for python there is PIL, and merging different images into one can be done with less than 10 lines of code, thats excellent.

I will wait anxious
