Could be like a particle box in blender or something and it moves billboards that are the smoke texture inside that box? or could just some sort of box that is named in blender to assign with some script that is used when the game loads up and reads the bike frame.jm?

Would be a cool feature to have, just these little things will really freshen the game up nicely. Tread marking is already a great step.

is there a way to toggle the tread decals on/off in-game?

I made a track script that essentially allows you to do this by logging the decals with their coordinates, angle, size, aspect, etc to lastlog.txt. You have to change what treadmark decals associate with what tile number.

You also have to get rid of the date logs, usually doing it with:

Code: Select all

grep -o '@@@<TREAD_NAME>.*@@@' lastlog.txt > treads.txt

where <TREAD_NAME> is the name of the decal in the track script. It will output to a file in the same directory named "treads.txt" Then you can remove the @@@'s in notepad or any other text editor. The only downside to this script is it doesn't have the customization that jlv's has with different speeds dropping different decals and choosing whether to do front or rear or both wheels (it only does rear wheel). I could easily modify the script to do this but not sure how useful it would be.

Here's the script if anyone wants to save treadmarks. If anyone actually uses this and wants me to modify it to meet jlv's treadmark code, then I can do that.

Code: Select all

// Position and velocity variables for riders rear tire
var rearTirePos = [], rearTireVel = [];

// Running order variable
var globalRunningOrder;

// Change the name to your track folder
const trackFolderName = "@TRACKFOLDERHERE";

• Fixed toggledecals.
• Fixed upsampling to use bilinear filtering when treadmark color/norm/spec maps have mismatched sizes. Previously used point sampling
