I would like to re-use the same models of the rubble piles around the buildings since this would cut a few megs off the final pk3 file size but the size, rotation and offsets of the rubble piles would need to be different for each building. Currently the base points are just aligned so a different model file of the rubble would be needed in each case.
I would like to propose the following additions (in bold) to the MODELDEF lump:
Model MultiModel
{
Path "Models/MyModel"
Model 0 Builing_model.md3
Skin 0 Builing_model.jpg
Model 1 Rubble_Model.md3
Skin 1 Rubble_Model.jpg
ScaleM 1 1.5 1.5 1.0 <--includes index number of model
OffsetM 1 100 100 0 <--includes index number of model
PitchOffsetM 1 45 <--includes index number of model
RoofOffsetM 1 45 <--includes index number of model
Scale 1.0 1.0 1.0
Frame FRAM A 0 0 // All models are drawn when you call frame "FRAM A"
Frame FRAM A 1 0
Frame FRAM A 2 0
Frame FRAM A 3 0
}
