I had some flashbacks, somehow still had it bookmarked. Is this related to this old script? https://forum.mxsimulator.com/viewtopic ... 332#p73332

No. This needed a lot of reworking of the track texturing so it can efficiently handle the special case of new decals added on top of everything else. Also has the treadmark decals in an atlas so it can draw everything without switching textures. Would have been hopeless getting this running on older GPUs that didn't support framebuffer objects and shaders.

Funny seeing those old posts though! Worrying about those decals being too slow and now it's pretty fast with hundreds of thousands of treadmark decals on integrated graphics.

Great update!

Could there be an offset parameter for roost decals and is there a way to dedicate a decal only to the rear wheel? And could that offset and size be a function of slip_threshold? I'm picturing in my head how faster slip would generate a longer decal for the roost to land on.

Could one line if matched drop two different decals? One beneath the wheel and one dynamic roost?

Below is just a red roost decal with empty space in front to move the visible part from under the wheel to behind the wheel. I guess the front wheel slipped enough on the lower line.

Good point on the offset parameter. I think I'll add that. I don't think scaling by the slip speed would be a good idea though. Better to just use different decals and select which to use via slip_threshold.

It's somewhat important to keep the decal count down. Dropping 2 in the same spot would be a waste when you can just combine them beforehand into the roost decal.

It wouldn't be too hard to do but things like that turn into death by a thousand cuts. I want to focus on bigger things. The next big update will be the culmination of the terrain rendering optimizations. After that I'm not sure but probably shading via HDR environment maps.

The shading would be amazing. The tread marks help the game so much already environmentally and shadows would be a cherry on top. Thank you jlv!

Missed this the first time I read your post. Yes, there is.

front=-1
This lets you make the treadmark specific to either the front or rear wheel. 0 is rear, 1 is front, -1 is either.

The documentation is here.

Does the time trial ghost keep dropping decals after its first lap? I think that its line is more dark than just from one lap after a while.

Yeah. It'd be fairly difficult to avoid it.

When I download the snapshot it says the file was blocked because it can harm the device is there any way to fix that.

Might help to disable the antivirus software that's blocking it while you install.

After I installed the latest snapshot, I can't join multi player servers from the server index. I can only join servers that I've recently joined from inside the game.

When you launch the game from a link on the server page it tries to run "C:\Program Files (x86)\MX Simulator\mx.exe" by default. So make sure that file is there. Be aware that the ".exe" extension is hidden in File Explorer so it'll just be an application named "mx".

I am switching back to 2022-05-19 snapshot. It works the best for me, no issues with graphics or lag

When I go into spy mode tiles turn solid black wherever I take the camera to. Is there any fixes because I was wanting to get some sick SS with these tread marks?

I think this is an Nvidia bug. I haven't managed to replicate yet so I don't have a workaround. Been meaning to take another shot at it. Apparently it only happens if you have your settings turned up in Nvidia control panel. More info in this topic.
