Hello, I converted another articulation part for my articulated bus, but when I spawn the trailer, it seems that the trailer doesn't even have collisions, but in zmodeler there are collisions, please help me https://www.youtube.com/watch?v=99Ivoi68Rvs When I manage to attach the joints, the trailer...

I have several liveries ready for my vehicles, I wanted to add the multi-skins system, I see several mods with this system

apparently I have to play for a while and then I spawn him, but his paint turns black and he crashes the game quickly

Oleg wrote: ↑Sat Dec 02, 2023 11:07 am most likely it is some part with collision attached.

I didn't find anything like that either, it still doesn't work

Oleg wrote: ↑Sat Dec 02, 2023 10:15 am I would start removing parts and reducing vehicle hierarchy/collisions complexity until stability is reached in game. this might give a clue on what exactly the game doesn't like about this model.

I deleted 90% of the parts and it still doesn't work lol

I have seen something like that when the vehicle's physics was bad. some physics element fall through the ground and the vehicle's "boundary size" starts to grow rapidly. Game's resource manager considers it requires higher and higher range to be available for drawing and starts to drop q...

When I try to spawn the vehicle in the game (trash), the vehicle itself does not appear and the map has those bugs with missing textures and buildings, poor processing, etc.

PS: which I spawn in the video is trash2, I only modified the normal one

MysticCat

Is there any way I can edit the topic to say that it has already been resolved?

Oleg wrote: ↑Thu Nov 23, 2023 11:57 am it might be some axes issue too. as a temporary fix, you can move front wheels (and their collisions) a bit up.

He's already perfect! thank you for real!

MysticCat

the issue might be related to some collision bumping out of the bus to the ground, so bus "skids" on road with this collision object instead of riding on wheels. in particular, you can make some light poles and road signs to fall onto the ground and try to push them with some vehicle unde...

I think your converted bus should be somewhat similar in position relative to original bus. Vertical position of entire scene could have impact on physics in game. That is why following the guideline of original bus is suggested. Update: the bus has now stopped skidding, after I moved it a little f...

But I did that, but it's giving me this error that I can't fix

MysticCat

have you tried to load original bus model to compare scene position to yours? and to compare physics values (Mass, E) ? Bro, when I went to convert my bus, I simply dragged what I wanted to convert to the same position as the bus in the original game, because what I was going to convert was in a hi...

Also, what is the Mass value in user-defined options on chassis[COL] object?

and it wasn't because I moved it too far, I think, I tried to fix it by moving it a little down and forward but it still looked like this

no. the hierarchy's topmost element. it should have a model's name (or model's name with "_hi" on the end). "chassis" is a child of this node. So, this root node and "chassis" should have local axes at 0,0,0 point ("Reset to world" tool does this). The object...

Oleg wrote: ↑Wed Nov 22, 2023 4:11 am none of that. entire scene (L0 models and collisions, everything) should be moved. then "reset axes" on main dummy node and chassis object.

The dummy would be the chassis_dummy, right?

MysticCat

Move entire scene (geometry, collisions and dummies) to the right and a bit up. You can move just root dummy node with Move tool and "Affect children" option toggled on. You can select this node in hierarchy view with Alt+click on visibility icon. To move "pre-selected" objects,...

object's axes are moved with "Move" tool. You need to toggle an option "Move axes only" before moving.

MysticCat

it looks like you have bad physics data on a model. Make sure to assign some-what real "Mass" values on COL objects. Also, the local axes of every COL object is the center of mass - you might need to move axes lower for chassis and slightly toward the front part. It looks like center of m...

Please help me! It's my first conversion and I just need to fix this, the front wheels of my vehicle are skidding and it's very difficult to drive, it feels like it's sliding, in addition to the suspension being very low on the rear wheels.
