actually you just have to add a second uv-set to the model in blender.

I would like to combine two textures in blender.
One texture with baked AO, and one with baked rendered shadows.
Any hints how to achieve that?

i think you have to set up a material which blends the ao and shadow textures in the wanted way and then do a bake with "textures" enabled.

you could also use the compositor. maybe that would be easier.

I don't find a way to add a second uv. The way I try it, replaces the uv only by the new layout.

the editing buttons contain a mesh panel with "UV Texture [New]". by pressing the [New] button you can add an uv-set.

I've got that in blender now, but it doesn't export 2 skins to MED.

you use the level exporter, right? can you show a screenshot of blender?

the official old mdl7 exporter for animated models doesn't support two uv-sets. (there is an experimental quickly modified version of the old mdl7 exporter that supports two uv-sets but i would have to look for it.)

Ah, sorry, probably that's the reason.
I didn't make a difference between level exporter and the mdl7 exporter.
I have a look into this.

I've used the export $$m now, but the resulting mdl has still only one skin.

What sort of screenshot do you want?
When I opened the export options?
Or, with the two texture buttons?
...?

a screenshot with the two texture buttons. or the blend file.

i am not sure if this is necessary but did you assign textures to both uv-sets?
