Summary	0005116: Export patches: .ase has too many verts
Description	While re-exporting models in DR has been working fine, exporting patches as an .ase creates a model that has too many verts: so i.e. a cylinder with 32 polys will have 96 verts (each poly has 3 own verts). This doesn't seem to have any effect on ingame rendering. The excess of verts persists when I import the model into Blender 2.79b. In the above example with the cylinder, I'm able to remove 64 verts when removing doubles.
Steps To Reproduce	1) Create a cylinder patch, give it ship_hull_medium as a texture and change subdivisions to 4 horizontal and 1 vertical. This shape has 34 vertices and 32 polys. 2) Select the cylinder and 'Export selected as model' with these settings Output Format: .ase Center objects around origin Skip surfaces textured with caulk The model has 3 verts for every 1 poly.
Additional Information	Tested & confirmed in 2.6, 2.7pre2, 2.7pre3 The attached archive and image also contains .lwo exports of a patch, as those are also misbehaving. (0005115)

Bikerdude 01.05.2020 12:49 reporter ~0012444	@Dragofer, might be worth testing this in 2.08 pre5 to see if the issue is still present

Bikerdude 17.11.2020 15:36 reporter ~0012965	Is this related to 0005383?

Dragofer 17.11.2020 18:40 developer ~0012969	Not really, .ase meshes really do contain too much vertex data. This gets revealed when importing into Blender, where removing doubles gets rid of a ton of vertices (i.e. 96 gets reduced to 32). But I think TDM has some kind of inbuilt removal of vertex doubles for .ase's, so they still look smooth ingame.

Bikerdude 17.11.2020 19:07 reporter ~0012971	Ok will test it in 2.9pre3 just to see if its still present.
