Importing Models to Roblox Studio + Advice

So I am a Blender modeler who imports models into Roblox. The issue I have had is that the import limit into Roblox Studio is 10k tris… which results in something like this:

Altogether the model is 8,920 tris. While I would accept this as fine, though I dearly wish to add more detail, this seems to be the limit.

I took a look at tank models available for free and found that they happened to have at times over 100k tris.

Now, my main question is: What can I do to add more detail to these models whilst still using Blender as a modeling software?

Further questions are:
Is a vehicle with 100k tris realistic to be driving around in a Roblox game without any issues of someone’s PC not being powerful enough to run it?

What would you recommend the tri count be for a vehicle that size, under the circumstances that it is a model the player drives, and there will be many like it in the game.

Also with texturing the vehicles, what would be considered too high of a resolution for Roblox (if this makes sense, speaking of texture maps (1k, 2k, 4k)?

Does Roblox support UDIM textures?

With modeling my tank, should I have the parts that move (turret, gun+ mantlet, roadwheels, tracks) be seperated as different objects for the player to be able to move them around?

Sorry if this is a lot and doesnt make sense I just want to clarify a few things before I even start making models so I dont have to change something on all of them down the road.

If the tri count limit is holding you back, you can just seperate your parts.
Mesh 1 has 8k tri,
Mesh 2 has the deatils (an extra 5k tri),

Combine it together in a model, there you go.

If you still having problem you can lower the polygons in Blender.
Just press the wrench icon in layer panel(the right side of your screen)
then press add modifiers then select decimate.
After than a dialogue box will show. Customize the ratio box. It should be 1. But you can change it to .8 or .7 but don’t change too far or it will break. (Blender 2.8)
Hope this helped!

Yeah I had already used the decimate modifier to lower the tri count to sub 10k.

Interesting idea, I’ll try to do that.

You could reduce the ammount of polygons/detail on it or possibly split it up into sections.
