I got your e-mail. I don't understand what all the files are. How did you make the .uvs files? They have a comment that says they were make in UVMapper at the top. Similarly the .obj files both say they were made by UVmapper. Anim8or writes a different comment at the top of the file when it exports to .obj format by both the built in and plug-in exporters.
Can you explain the sequence of steps that you did?
When you export from anim8or you lose groups (and materials in earlier versions). If you have two identical geometries, and assign materials and groups and lay out the uv coordinates in one model, you can save that model and also export a .uvs file, then open the unmapped geometry in UVMapper, and Import uvs; it will assign them to it just as in the first model. Voila: groups and materials in both models. This will only work if the geometry in both models is identical.
Build model in anim8or.
Export as HP_OltonHall.obj
close anim8or
Open UVMapperPro
Import HP_OltonHall.obj
Lay out UVs, assign textures and groups, save HP_OltonHall.obj.
Export uvs.
close UVMapperPro.
Open HP_OltonHall.obj with anim8or ver .95. Select some vertices and move them. (Do not detach faces or in any way change the geometry other than scaling or moving.) In my case I wanted the boiler a bit shorter so i selected the verts on it and moved them.
Export HP_OltonHallExported.obj
close anim8or
Open HP_OltonHallExported.obj with UVMapperPro. You will see the changes you made in the verts and also there will be a default group and default material.
Import uvs -- select HP_OltonHall.uvs
UVMapperPro will apply the mapping, groups, and materials from the first model to this modified and exported one. Save the model as HP_OltonHallFinal.
Here's the test:
Now try it with version 97b. You will get an error reading Incompatible facet structure. Something has changed in the model from the export from anim8or. I've used anim8or and UVMapper with this method for years; this new version adds verts or faces or something.
