1ROAD

finish AC_AB_FINISH_L AC_AB_FINISH_R

start AC_AB_START_R AC_AB_START_L AC_HOTLAP_START_0 AC_PIT_0

Place them 1 or 2 meters above track surface. Three conditions to make sure everything will work as expected:

respect the naming scheme
make then invisible
make sure to respect the axis orientation (pivot point Y up, Z forward) (rotate axis X 90)

Road modelling

set the origin of the track to the origin of the world (0,0,0)
convert the curve to bezier, change the control points, then recalculate normals
apply the transforms before texturing it. In object mode, press Control-A Scale

https://blender.stackexchange.com/questions/8808/what-is-the-fastest-way-to-add-vertices-to-a-curve-at-a-specific-point

set the origin to the bezier
- bezier res: 24
- bezier Twist method: zUp
create plane add array modifier - set uv - set merge - set merge distance to 0 add curve modifier - get the curve - calculate the length

Apply the Array, delete the Curve. Control-A apply all the transformation Map the UV First 2 using smart Rest Follow quad

Add a new curve modifier - Select the bezier

fix for GPX-Import in Blender 2.8.2

/Users/assman/Library/Application Support/Blender/2.82/scripts/addons/blender-gpx-master/init.py:227

        projection = None
        if "bpyproj" in self.__dict__ and self.bpyproj:
            projection = self.bpyproj.getProjection(lat, lon)
        if not projection:
            from .transverse_mercator import TransverseMercator
            # fall back to the Transverse Mercator
            projection = TransverseMercator(lat=lat, lon=lon)
        return projection

how to fix the pyproj problem (install binary dependencies on Blender)

In order to get https://github.com/vvoovv/blender-gpx/wiki/Documentation this work, we need https://github.com/JeremyBYU/bpyproj dependency and proj installed. But the build requires some tunning in the @rpath so this is how to fix the plugin

OSM

works awesome

how to fix elevation GPX problem

set the Z (top) orto view
go to first point of GPX
3d cursor, get the Z value
select in the terrain the face. Set the origin to THAT face
Move the terrain Z to the Z value recorded in step (2) from GPX.

blender distance

distances should be calculated in this way:

#vp = bpy.data.objects['Plane'].data.vertices[37] #vt = bpy.data.meshes['Terrain'].vertices[24449] #vp = Vector((-33.21149826049805, -8.433300971984863, 6.760486125946045)) #vt = Vector((-129.67138671875, -46.43072509765625, 3.25))

goal distance (marked by measure tool: 6.307367787950501)

#vpw = bpy.data.objects['Plane'].matrix_world @ vp.co #vtw = bpy.data.objects['Terrain'].matrix_world @ vt.co

#d1 = (vp.co.xyz - vt.co.xyz).length #d2 = (vpw.xyz - vtw.xyz).length ## this one! #d3 = (vpw.xy - vtw.xy).length # 2d

#print("distance 1: ", d1) #print("distance 2: ", d2) #print("distance 3: ", d3)

call OSM

bpy.context.scene.blender_osm.dataType = 'osm' bpy.ops.blender_osm.import_data()

print(bpy.context.scene.blender_osm.maxLat) # top 40.33190155029297
