Making a Realistic Car with A-Chassis & Blender

Ah! Alright so you can separate each piece by doing the following stuff:

At the top left, you’ll find something that says “Object mode”.

Click on it, and then click on “Edit Mode”.

This will happen. Alright so now press “P” on your keyboard and then click on Separate by Material.
image

Now as you can see, the car will separate into pieces with the same material.

For better handling, you can select all and again, click on Edit Mode.
Then press P and select “Separate by Loose Parts”
image

And as you can see, every piece of the car is separated and you can start working :smiley: !

I hope this helps! Tell me if you have any other doubts!

Thank you for this, but now I have an issue when I import into studio that the colour of the car is gone. I haven’t imported it fully but this is what it looks like so far in the game.

Don’t worry. You can color it inside Roblox Studio!

Another issue haha. Some pieces they import fine but there are some other pieces and they just don’t import. I have tried in both .obj and .fbx format and followed their guide here. Other parts have imported fine like I said and I can add textures and colour but a couple just won’t import. Here is the image:

and the errors too:

and using a normal mesh it says inappropriate name sometimes but I tried to just import the letter ‘R’??

This is maybe because of Roblox’s filter. Some names can be inappropriate for Roblox.

You can try to import them with different names, for example, “Right_Side”.


There’s a bug when importing.

Sometimes, when you click on “Import with location” the piece will not be imported.
So in this case, you’ll have to click on “Import with location” many times, until you see the piece in the workspace.


You can also try to use the “Double-sided” property, this will make the mesh visible on every side.

This is useful if your mesh is in the workspace but you cannot see it.


I hope this helps you! And ask me if you have any other doubts! :smiley:

I have tried importing the mesh so many times on different computers and on different days and times. It just will not import.

Could this be an issue of the tri-count being above the roblox import limit, if its above 10k tris then roblox wont allow you to upload it, what also might be handy is to merge the vertices by distance in blender, which will help to remove overlapping vertices. In object edit mode, press a to select everything then press m > merge by distance, and it should show how many vertices it merged in the bottom middle. this is really handy if there’s any issues with vertex normals, and shading.

No it isn’t, using this tool it says it has removed 29 vertices and it doesn’t say over 10k triangles. When I tried to import something intentionally with over 10k triangles it just said the error was because it went over the limit.

EDIT: After enabling the feature to see how many triangles your model has I am now 100% sure that it is under 10k.

That is weird. I tried to import some meshes with different names, and they imported.

I’ve also tried to import it with different options and it works perfectly!

Maybe you can try to check this website and see if you can solve your issue!


Solution 2

Try to join the pieces that can’t be imported with some other pieces and check if it works!

Tell us if you have any other problems! :smiley:

when driving my wheels wobble and a my car slips when going fast?

Copy and paste the Wheel Position to the mesh wheels position to move it into the middle of the tire.

Also the chassis you are using has been outdated for sometime. A-Chassis is now being developed by novena: NVNA - Roblox
Their discord: NVNA
Link to Latest Chassis: A-Chassis 6 C Version 1.5 - Roblox
Grav Compensation: H_GRAVCOMP_CONTROL_MODUL_1.rbxm (112.4 KB) (Help: Discord)

what the grav thingy controling?

Basically, it compensates for gravity so if u make a jump gravity will be applied to the car. Plus it comes with some great plugins.

thats cool! i might use it! just put in plugins right?

Nah its just a chassis that has some plugins pre-installed like a upgraded version of the tire wear.

in blender you need to press shift + n, to recalculate the normals, on a lot of the parts it appears the normals on the faces are inside rather than outside.

Also keep note to Anchor the mesh wheels and rims too! Or they will be weird and sideways.

It would like me to download the latest version of Sketchup, is it paid access? It won’t let me import files, nothing! unless I download the latest version.

Awesome job, but I think you should make a playable game so people can test this out and see if it’s something they want to spend time working on if they like it.
