What does ctrl+i do in lfs editor?
On both the modeller and vehicle editor it shows image not loaded in the bottom left corner, but in the modeller it makes the whole screen gray, in the vehicle editor the floor turns grey.

Hello Scawen, how are you? I'm doing a big and very important project with a studio (Can't spoil too much right now 🙃), i really need your help, i am making a formula but im having problems with my rear suspensions: i'm getting too much damage on the dampers and much more damage on high speed corners(EX: We2 Turn 1). it has a lot of downforce and i wonder if is possible to make stronger suspensions, if its not possible what else can i do to fix it? Here's a video:
Thank you!
Regards.

U can fix it. There's some Single-Seaters cars with aero that work and XF GTi Rally that have suspension prepared for huge jumps. IDK what exactly u need to do, u need to ask physics guys.
Try to play with Half Uprights, Max Up and suspension hardness in setup.

I found that bigger rim sizes fall underground in a specific place on Westhill's track. Maybe you can inspect the difference at some point between the other road and this specific location of the road. (image is attached)

Cheers.

What do SA and SR mean in the suspension diagram? They must be tyre-related since they are affected by the tyre compound, pressure, width and car mass. I thought it could be the peak slip angle and slip ratio, but the grippier the tyres are, the less the SA angle is, so I'm a bit confused about these.

First thing I should say is it only relates to the new tyre physics system and not the public version, in any way.

They are supposed to be an estimate of slip angle and slip ratio at the peak of lateral or longitudinal force. But it is just an estimate based on an earlier version of the tyre model. In fact there is a comment beside the function:

// TYRE TODO - very inaccurate

This function is currently only used in these diagrams and in some estimates for AI drivers and keyboard steering. It's not actually used in the physics, although it should represent it to some extent.

It is based on a simple function with a few multiplications and a division. It doesn't take a reading from the actual output forces and really it shouldn't be displayed in the editor at all at this point.

Anyway, that function is supposed to report an increase in the estimated slip angle (and ratio) at the peak, as grip increases, and also as tread stiffness decreases.

That's what I'm seeing with the Formula XR rear tyres:
R1: mu 1.61 SA 1.8 SR 3.2
R2: mu 1.52 SA 1.3 SR 2.3
R3: mu 1.47 SA 1.0 SR 1.7

But that doesn't correspond with what you said. In this case the inaccurate formula predicts that grippier tyres will produce a wider slip angle at peak lateral force, which is what I would expect.

Thanks for the explanation!

I checked again and it works as expected, you're right. It must've been an oversight on my side before.

Hey i hope this isn't a dumb question, but i've a load of mappings with triangles mapped to them that i cannot seem to unmap. My ultimate goal is to delete all mappings, cutouts and textures, and start from scratch, but i dont seem to be able

You can create a new mapping, then select all tris and assign these tris to the new mapping. Now everything is unmapped without texture and you can start from scratch.

Then you can delete the cutouts & mappings in the tabs if you want to.

Running into issues with creating my own pages from my own png.
I get hit with 'Invalid texture TR_interior1 - Invalid file'
Properties include:
Location - C:\LFS_EDITOR\data\png
Dimensions: 512x512
Bit depth: 24
file type: png

(tbh this is probably an issue with the fact that I'm new to the mod-making scene, if so, tips would be appreciated)

The message "Invalid file" comes up if a dds file or a png file has the wrong header (the first few bytes of the file). Are you able to open that file using other software?

One possible cause (other than a corrupted file) is that a file of one type was renamed to another file type, by changing the filename extension. That cannot work, of course. LFS will create dds files from png files when required. You should use png files in the LFS editor and just forget about the dds files because LFS will create them for you when you do an export.
