Clothing problem

[User528]

Windows Vista, makehuman nightly 22.03.2012, blender 2.61
I create two characters with makehuman and I save them as .mhm files. I export them too, as .mhx files. One of the characters is naked, the other one is dressed. When I import them in blender, the rendering works fine. So far so good.
Later on, I open the .mhm file belonging to the naked character and I "dress it up", i.e. I add some clothes to it. I export it again as .mhx, then I import it in blender. On rendering, only the clothes appear.
Am I doing something wrong or is it a bug?
Thanks in advance.

Sounds like your texture images are not where Blender thinks that they are. Have you moved something - a texture, a blend file, a directory?

Anyway, the problem is easy to fix. Select the skin material, and then the skin texture. In the Image section, find the path to the image (the open folder symbol opens a filebrowser).

Thank you ThomasL for the quick answer and for the hint. I am a little bit ashamed for my delay, unfortunately business can't wait...
First the due answer: no, I didn't move any files, directories or whatever. As the forum's name says, I'm a newbie, therefore I try not to interfere with processes I don't understand enough.

I did some research and came to the following results:
- On creating a character from scratch and on exporting it immediately as .mhx, all the needed texture images are being saved in the corresponding makehuman\exports\<character name>\textures folder. Therefore, on importing it in blender, the rendering works without problems.
- If the previously-created character has been saved as an .mhm file too, opening it in a future work session, modifying it and exporting it again as .mhx under the same name leads again to a file structure which can be correctly imported and rendered in blender.
- Problems appear on trying to work on characters which on creation time haven't been exported at all as .mhx, but only saved as .mhm. On opening such an .mhm file and on exporting it as .mhx, makehuman fails to save the makehuman\exports\<character name>\textures\texture.tif file. That is the character's skin texture file, therefore blender can't render it appropriately.
- Similar problems appear with characters which have to be exported as .mhx under another name than on creation time. In that case, makehuman fails again to save the makehuman\exports\<new character name>\textures\texture.tif.

Possible workarounds (until the nice makehuman designers remove the bug):
On creating makehuman characters intended to be exported as .mhx, all skin texture-related work should be done on creation time. Export immediately an .mhx version after that part of the work is done. Make a backup copy of the makehuman\exports\<character name>\textures\texture.tif file. From now on, every new .mhx export is safe. If you notice that the blender-imported character can't be rendered, just copy your texture.tif backup in the corresponding makehuman\exports\<character name>\textures folder, then import it again in blender.

As far as I'm concerned, the topic is closed (actually, its name should be changed from "clothing problem" to "skin texture problem").
