I can't help with the resource hunt - but that's a great model!

What's the tris?

Why would you not want to use the BT tank pack, it is exactly what you want. the models has independant suspension on the tracks like a real tank, it has a main weapons as well as a secondary weapon function built inwith full turret and movement functionality. Seems like a logical place at least to start.. I have not found a better one, and if your searching it gives you at least something realistic while your waiting on... well im not sure what your waiting on. a home grown version?

Your models are great btw. Keep up the good work.

Beautiful model! Agree with Edward, the BraveTree: Tank Pack (which is not the CSK) has some interesting features for your tank. Cant remember of any other resource...

Edit: you will find this blog rather interesting.

I don't think there are any free resources for tracked vehicles, it seems when someone made a tank vehicle they sold it. I can't blame you for not wanting to use the TankPack or the CSK, though it will be a lot of work. But you can make a start with the Conform to Ground resource, and you would have to add emitters and treadmark decals to the tracks, and handle suspension in the source. Same for the gun turrets. You would end up with a new class of vehicle all together.

But awesome looking tank!

Tris: 6000
tools: maya,photoshop

i am thinking to make tank pack by myself, so think its better to contact with coder and make it together... also will add normal maps and specular to make this tank looks better...

The conform to terrain resource is unneccessary - I assume you want your tank to be a vehicle, not a player? I'll be working on tracked vehicles at *some point* in the future, so if you're looking at the same thing, we could collaborate on a free resource for people.

That blog is interesting, and basically what I had in mind for tracked vehicles. There is the 'hanging' problem, which we'd need to work around somehow. A little while ago, I actualy prototyped some crappy tank-steering physics. I just made a script property that made the vehicle 'tank turn' - so wheel speed was based on the steering of the vehicle as well as the forward motion.
In short:
Hold forward - all wheels ahead full
Hold right - left wheels ahead full, right wheels back full
Hold left - right wheels ahead full, left wheels back full
Any combination of those - one side ahead full, the other side neutral

This worked pretty well. Just the traction might give some problems.

As for hanging, maybe some raycasts between wheels would be in order - as in, doing a cast along the point where the tread would actually be, instead of from the hubs of the wheels downwards.

Oh yeah. That tank model is amazing! That skin makes it look damn near photorealistic (at least, as far as I can see :P).

Nice model. What version of the T-90 tank is it? If its the old "S" version the turret shape might be modeled wrong.

But again, this might be a new variant that I am not aware of.

This is version for russian military forces only. with "shtora" active defence system...
t-90s is export version mostly done for india, "s" version more simple and contain only basic defensive systems
main references for this model - from spring parade in moscow...

the model you provided has old styled turret, mostly from modified t-72 and not very closely to latest version of MBT-90 "Vladimir" with new turret...

I know this is an older thread but I am currently creating a T-72 tank in Maya. I have pretty much all of the modeling done and now I am moving on to texturing it. I have been having a hell of a time getting it to look right. Your tank looks great, what size texture maps did you use?

2 textures 1024x1024 each
+ animated texture for treads

so you unwrapped everything as a single object? That may be my problem, I have every thing as multiple objects and unwrapping them as multiple objects.

texture objects:
- tank body (including wheels, this is wrong)
- tank turret (with AA machinegun, this is wrong )
- treads

its better to unwrap wheels to separate texture, so u can rotate them via shader or UV script or whatever.
also u need separate texture for the addons, like AA machinegun or any optional switching upgrades (maybe additional antenna)
