BMW M6 GT3 rear tyre position issue

In the showroom mode, the position of the rear tire is correctly displayed, but the position is shifted and displayed in the actual game (white line). Also, the gap between the tire and the wheel arch is different between the showroom mode and the actual game (green line).

It could be there is a slight difference, but you're also not using the same camera zoom and FOV in the showroom vs on track. The showroom goes very wide when you close in.

 

The showroom use 3D pivot position for wheels, and in game it use physics values to place wheels.

 

MaD_King Also wrote, but the position of the wheels in the game because it depends on the physics, I think that it is not the difference by the FOV.

 

I'm slightly concerned that you know this but the developer don't (at least thats what it looks like )

 

My point is to make a real comparison (and measurement) both shots FOV and angle should be identical

 

Yes So to check on S397 Devs for a possible issue in Wheelbase or Pivot in Showroom

 

I think @Christopher is saying the camera in the showroom is not the same camera on the track. It's starting point of it's FOV in the showroom probably does not match the initial FOV on track. (perhaps we could say the showroom may have a slight fisheye to accentuate the close up images) I suspect that even if you know all the angles and numbers regarding the showroom camera, you may not be able to duplicate that on-track.

 

I also think that there is a small kind of a bug in the showroom.
A friend of mine pointed me to it.
If a car, that has the pivots of the objects, that are in the wheel and spindle instances, set to 0,0,0, the front wheels are always a little bit in the air and don't touch the ground.
So it seems as if the cars physics has an influence in the showroom too, at least for the front wheels.

 

Same thing hapened in RF1,i solve this changing the name of the wheel instances.
Instance=RFTIRE,like this the front wheels stay in the air
Instance=RFTIRESPIN,like this works great

 

I tried it so that the FOV would be the same, but this is the limit.
After all, I think that the position of the rear tire is slightly different (the wheel base is long).

 

This, or S397 fixes it.

 

I just had a look at the BMW and the rear wheels definitely look too far rearward. They don't fill the wheel arch properly.

 

We'll look into this, if it needs to be adjusted we will

 

The rear wing shows the difference in camera position, which can't be 'fixed' by adjusting zoom. Not to say there's no issue (just as Chris hasn't said there's no issue) but it shows that they need to be the same in order to really make proper comparisons - albeit the wheel face is probably quite close to being flush with the wheel arch horizontally, so probably not that much difference.

 

the wheel base in the hdv is longer than the default positioning of the 3D, exactly as @MaD_King says.
