Just looking at the videos, it seems pretty clear that they're going to be multi-object and mult-textured source models. That doesn't mean it can't be done, but it does make it more complicated and difficult - Not just a simple convert and export job.

Well the modding community for HW is pretty active, so I'd assume it won't be too hard to obtain all neccesary data and process it.
Also you say mult-object models, what do you mean by this?

In the promo videos you can clearly see that at least some ships have rotating weapon turrets. That probably means that the turrets are separate 3D objects, with their own textures and UV maps. SR2 generally uses one object for the whole ship (multiples are possible but it's a bit of a hack job I'm told). In order to convert the Homeworld models, you'd have to combine them into 1 single object/mesh and do the same with the UV maps. That will probably make the job a fair bit more difficult.

In other words, what you are asking for is probably not a quick, simple job for someone to do. It's also likely why it hasn't already been done by one of the shipset modders already.

Well I understand that it might not be possible to do it that case (atleast not without significant difficulty). It would be nice if it could be done though, and I'd be willing to help out in the process if I can in some way.

Sure. It would be nice to see happen. I was mainly just trying to point out that it's probably not as easy a task as it might seem. At least not compared to porting over ship models from some other games.

There are some other multi-object orignal ships converted to SR2 for other shipsets already. The DOF Star Wars shipset (as well as Titanicus' original set) were sourced from multi-object originals in many cases. There are things missing though; compromises made to make it easier. Definitely more work to convert than say stuff from SoaSE content though.

One could just merge down turret parts etc. to main hulls and "ignore" turret aiming - or all together skip turrets. If I remember correctly the latter is how it was done for the SR1 port some modders did.

Done.

Nice one.
