    Untitled-1.png Hi guys, cant believe i was not using this forum before. Can anyone help me to make the racing groove using 3ds Max?
    I know it must be a new 3d a few centimeter above the track. I already did that. The problem is the shape of this new 3d is the same as the road. I need it to be the "fast line" as the original tracks. I dont know what to do? So far all i have is a spline over the track with the fastest line shape, but when i extrude it to make the groove it doesnt folow the track banking, so it is not usable. To get the fastest line spline i used this tool for RF. Thanks. http://www.mj-multimedia.net/2012/03/gmaterial-tool-for-3dsmax/

    Hi there, welcome to the forums :).
    I personally use Blender, but workflow should be similar.

    How did you obtain the original road ? Also using a spline ? If yes, why not copy the spline, adjust it to match a fast lane, and then extrude to obtain your groove. The advantage would be that the orientation of the spline would be identical (at least in theory).

    Also, don't forget to check the "banking" option - can't remember the name exactly but it's there, I've also used it to generate my ramp for the parking garage.

    Thanks luchian. The road is a convertion from Rfactor so no spline for it. I will try to apply a outline on the spline and conform to the road using this script. Hope it works.

    Interesting little tool. Hope it works out ! :).
    If not, I still have some ideas, but they are not really automatic :D

    Do you have a tutorial on how to create the grooveline in blender, importing the fastline.
    I already managed to import the ai file, but I don't know how to continue. Generally model in 3ds max. I imagine that I have to create a surface from that line and export it to 3ds and then assign it a texture.

    Hi Ariel,

    No need to go the blender route if you use max. The AI line helper tool can export a center line/groove CSV file which can be imported into max:

    How do I import that file? Because the csv format does not appear to import in 3ds ...

    if you already have ai line in blender, i tell you the blender way:
    select "fast_lane.ai", move it ie at the corners, so you have enough space for the new groove, use smooth proportional editng mode
    when done
    vertext select mode, a to select all
    CTRL+E -> OffsetEdges -> Extrude
    [​IMG]
    use 3 m or like 1/3 of the trackwidth
    [​IMG]
    CTRL+I to invert selection, so we have selected the center ai line again
    then again
    CTRL+E -> OffsetEdges -> Extrude, this time negative direction
    [​IMG]

    now check faces normals direction, maybe some are flipped

    finally you have to unwrapp this

    oh and after that you must
    -make a copy of all the ground layer-stuff
    -join it all together, call it "shrinktarget"
    -then add a shrinkwrap modifier to "fast_lane.ai" with target "shrinktarget"
    -play with "Offset"

    I am more used to using 3ds max. Do you know how to import the csv file created with the iahelper?

    no, but if you have it in blender, just export from there as fbx or collada, 3dmax knows that

    Import the fastlane. Then I made it mesh. But I can't find how to do what you tell me ... I select the line that is orange. And I can't find smooth.

    you can then mouse scroll to influence range of movement (white circle)

    maybe you must subdivide once or twice to get all the details wrapped without spikes of the road picking though your new surface, the mesh with "3 guide-lines" is probably too far spanning in places
