Texture and Material question

[Anonymous]

Hello everyone, 

I'm pretty new in the 3ds max "universe" and after hours of research on the internet, I can't find any solution to my problem.

Maybe someone here would give me a clue to solve it.

I've got a mesh of a road made with a laser scanner / cloud points, and I have to apply a texture on it. The texture must follow the road path and turns.

The result of the scan is a perfect copy of the real road, with near 350 000 faces and more than 1M of points.

I tried to use a simple UVW Mapping, but the result is that the texture don't follow the road path.

An UVW Unwrap would make the material fit on every faces and not on the entire mesh.

The big problem in this project is that I must keep the mesh intact to keep the perfect copy of the road.

Thanks for your help 😞

I think the best solution is to create an spline following the road and use spline mapping in the unwrap.

Here's an explanation about it: https://knowledge.autodesk.com/support/3ds-max/learn-explore/caas/CloudHelp/cloudhelp/2017/ENU/3DSMa...

Thanks a lot for your answer !

I've a big work to finish before I can try this method, I hope I'll be able to try this for monday.

Thanks again  !

Thanks again fla3d for yout answer.

I've tried your method and it seems to be a good way for texturing my mesh, but I don't know why, I can't find a way to make my texture fit correctly 😞

is there more important values to take care of before applying the spline mapping ?

When using spline mapping you usually needs to tile your texture in the V coordinate to avoid stretching or adjust it in the UVW map. In this case, you first need to rotate your bitmap 90 degrees in the W coordinate and then tile in the U link in this example:
