I have made some 3D Models with LOD for F4 BMS.
Most of them has LOD0 from 20k to 30k Triangles, also these 3D Models should be very performant inside DCS engine. 3 lower LODs and textures are available too.
Only one seriously work is to convert F4 DOFs and switches to DCS usable bones.
Here is a small preview for my 3D models.
Mig-23Ml 20k tris
Mig-25 23k tris
Mig-27 22k tris
Mig-29 A, G, S 28k triangles
Mig-29M 28k tris
An-24 20k tris
AV-8B 32k tris
Su-24 30k tris
Rafale 32k tris
B1-B 30k tris
What do You think, what is the best choice to begin converting to DCS?
