Default export texture map to SL

I just bought ac3d and I'm experimenting with the SL sculptie exporter, so far, it seems to be doing a good job, except that I'm missing the texture map...

Is there a way to export the sculptie's texture map that I loaded in ac3d?

To avoid confusion, I'm talking about the texture map, not the sculpt map.

I apologize if this question has been asked/answered before, I did search the forum first, but I didn't find a definitive answer (or I overlooked it).

I find this post well worth a 'bump', since I am currently doing the following:

Create a 'template' texture of boxes of multiple colors.

Create/Line up textures using said boxes, which requires (at times) 10 or so uploads of the new texture to test it in SL.

There are folks out there creating photo-realistic sculpted/textured prims, but I can't seem to figure out how they're doing it.

No need to waste precious Linden dollars on uploads, there are plenty of textured sculptie previewers, I like Rokuro Pro.

From the Object menu, click Load Texture.

Assuming you have not altered the offset or mapping mode in SL, the texture you see in AC3D should be mapped *identically* to the texture in SL.

If it's not matching for some reason, make sure that your subdivisions are up-to-date. Either commit your subdivisions, or *from the TCE* click Edit > Refresh Subdivisions.

Note: there is one known texture bug in the SL client. If you create a sculpted cube with *very* sharp corners, the texture warps only when you are standing right next to it... it looks fine if you take a step or two back. It's in the JIRA, I'm hoping they'll fix that one soon.

I've attached a texture you might find helpful for visualizing the UV map.

Oh also, if your texture map is super-warpy (like the top of the cube) it can be tricky to paint.

You can use the "bake texture" plugin to work-around that. Duplicate your shape, re-map it with some sane uvs, and paint it as desired. When you are done, bake the texture from the sanely-mapped shape back to the sculpted shape. You'll have a much easier time dealing with difficult texture coordinates that way.

Actually I have it the other way round, I have imported a 3d object that has textures already in it, not as a separate file, the texture is visible in the workspaces, but not in the TCE.
How do I save that texture as a 2D bitmap?

I've already tried the "bake texture" plugin (duplicated the object and then tried to save the file, but it took a very long time, and at the end, the file was not saved for some reason).

You can't (currently) save textures out of AC3D. Your best bet is to use a "Light-Mapper" to create a 2D light map and then texture the light map. I say that because the only real benefit to saving your texture after having introduced it into AC3D is to save the lighting information.

I recognize that light-map might be the correct term, since the term light-map usually refers to a texture used by renderers to generate lighting information.

Someone else could probably explain this better.

Gile[s] was suggested to me.

Edit: Textures are always a separate file. I don't know about procedural textures, but bitmap textures are.
