Go from there backwards:
The SU-100 & SU-85 hulls have identical dimensions (minus the height due to a hatch on the SU-85).
Both hulls are approximately 20' long, the SU-85 barrel makes the vehicle 6'9" longer & the SU-100 barrel makes it 10' longer (if I remember right).
The hulls are structured differently but essentially based on the same design and dimensions.
We did do research before deciding to make the chassis partially universal.
Even if what you said was the case it would make a negligible difference in game play as it's hardly noticeable.
The only reason for the rebuild is to increase in game performance.
That normal map though.... You do need more patience with me DM :)
Me & DM still have to muddle through animating all Variants first, then you have testing, please also consider that this is in and around our day to day lives so the answer at the moment is "how long is a piece of string".
The model mesh, UV mapping of both diffuse & occlusion channels are complete along with the textures for all variants so it shouldn't be too long, when we get time really.
Ugly, ugly model ;) must admit, DM almost gave me a heart attack when I saw he animated it :P
@carabinam1 as we have said multiple times, its incredibly time consuming animating just a single model,then you have to consider the time taken to do the mesh, uvmap it, skin it and then there is further complications with OE work and then implementation and balance. There will not be new factions added, reward units are a possibility.
Just a side note, we are currently re-working the Flak variant to have a similar cab to the Opel Blitz Flak truck but it's taken a little bit of time as me and DMz have not got the DataSrc files.
Were also looking into fixing a few Blitz bugs aswell.
