This model is so spesific sample about subway and railway tunnel. All part are rigged with only two spline. It is tileable and rotatable tunnel.

It is modelled and rigged with Cinema 4d

We didnt write polygon numbers because it's so variable, long or short. For Cinema 4d format, it hasnt big data polygon. Program shows me 6000 polygons. But model made spline and nurbs geometry

You can create unlimited 3d tunnel model with its control pannel.

CD4 file revised for spline sensitive and close/open all cloner. For easy use while adjust tunnel. You can adjust spline sensitive with rasinge or lovering.

Also we upload fbx, obj and stl format. They arent rigged and animated. But we upload 3 different shape for every converted format. Linear, curved and S form. Even you may want different shape from photos or you draw new line. But if you want so long tunnel for converted format its file size will be so big.

Thanks for interesting
