@Wjbender, thank you for this great contribution! I post this late answer, because I was worrying about that the merging wasn't perfect, there are some triangles off. I don't get that solved. I would be happy, if anybody offers an advice how to solve this!

Hi. I have not tested this much myself .it was more of a proof pf concept
written in an understandable manner for the poster of this thread . I could
look into it a bit further and see if perhaps i may be of help to you, provided
that you go into a bit more detail so that i may try and see what you see

Okay now i understand ,yes the rest of the function was poorly written
i was wondering how to achieve orientation and position and scale and skins
perhaps getmesh would return buffer with all that rotation positiom scale?
I havent tried it yet .position and scale shouldnt be to hard its the rotation
that bothers me im not very good with vectors and matrices. It would be
Great if you are able to solve the function

Maybe, one has to start with setting a center of the new model, and after that measure the vertex positions in relation to that center point.
Relaating the skin, I'm planing to sew the skins into one bitmap, and shift the vs depending the position of the models skin within the new bitmap.
Anyway, thank you very much for your base work, without it I wouldn't have any start at all.

That sounds great best of luck . Heres some form of code i have used
before
x=meshpos.x+vertex.x*scale.x
same for y and z
x being the new vertex position and scale taken from the source models position,vertex,scale
rotation i have no idea .
Anyway sure you wil solve it better and if you do could i ask for help
with rotating vertices as i need it for my navmesh project?

I got the rotation working. It is vec_rotate, inserted with VECTOR temp1; and the switch from y and z in the following way:
for (iterate=0;iterate<vertices1;iterate++)
{
temp1.x=vertex_buffer1[iterate].x;
temp1.y=vertex_buffer1[iterate].z;
temp1.z=vertex_buffer1[iterate].y;
vec_rotate(temp1.x, source1.pan);
merged_vertex_buffer[iterate].x=temp1.x;
merged_vertex_buffer[iterate].y=temp1.z;
merged_vertex_buffer[iterate].z=temp1.y;
merged_vertex_buffer[iterate].u1=vertex_buffer1[iterate].u1;
merged_vertex_buffer[iterate].v1=vertex_buffer1[iterate].v1;
merged_vertex_buffer[iterate].u2=vertex_buffer1[iterate].u2;
merged_vertex_buffer[iterate].v2=vertex_buffer1[iterate].v2;
}
offsetv+=vertices1;
for (iterate=0;iterate<vertices2;iterate++)
{
temp1.x=vertex_buffer1[iterate].x;
temp1.y=vertex_buffer1[iterate].z;
temp1.z=vertex_buffer1[iterate].y;
vec_rotate(temp1.x, source2.pan);
merged_vertex_buffer[iterate+offsetv].x=temp1.x;
merged_vertex_buffer[iterate+offsetv].y=temp1.z;
merged_vertex_buffer[iterate+offsetv].z=temp1.y;
merged_vertex_buffer[iterate+offsetv].u1=vertex_buffer2[iterate].u1;
merged_vertex_buffer[iterate+offsetv].v1=vertex_buffer2[iterate].v1;
merged_vertex_buffer[iterate+offsetv].u2=vertex_buffer2[iterate].u2;
merged_vertex_buffer[iterate+offsetv].v2=vertex_buffer2[iterate].v2;
}
