Well, I decided to try ripping models from YSFS with surfview. The VRML exported fine... and AC3D opened the file in question just fine... but I've got a rather unique situation now:
It seems VRML creates what is interpereted as a group of unassociated surfaces... which for some reason are not quantifiable as objects. This means I can't just select everything as objects, merge it, then weld all the verticies. However, the models are still useable - should I ever get permission to use them. What I've done is somewhat expensive timewise, but very simple to do. I'll select a few surfaces from a region, then save that region of the master model as a new file. I'll then divide it properly and create a 2D mesh with the appropriate number of verticies and surfaces. Then, it's just a matter of draging the verts into position...
The new mesh is a coherent object which can be managed easily. By combining the objects, a refined, optimized model can be produced.
Here's the next question: ssmit132, do you know of a better tool to extract/crack into the .drm files YSFS uses? Or something to create .drm files? There's a few models which I believe are too much for the programs you posted to handle. Then, there's a few models I'd like to edit and then put back into the sim... namely a few Super Hornets with fake weapons pre-attached... By the way, would you like me to try and get a hold of the Super hornet for this project?
