I have got parametric mapping to work on each side of a spline object if I use the full side. However I don't appear to be able to draw rectangle or polygons on more than one side of the objects. This image uses 2 rectangles for the front of the cab but the side window has to be all of the side to work using "white is transparent" option. Has anyone managed to get shapes onto more than one side?

Why not just bring it into vertex modeler then setup it's UV's and go to town that way? Cleaner and simpler then trying to get multiple layers of parametric mapping to work correctly. I always had problems trying to use parametric myself.

Hmmmmm, haven't had that problem before. I just did a quick test to see. What happens exactley when you attempt to draw another shape?

The editor appears to draw the shape on a different side to the one I want. Here is an example where I have tried to draw a polygon on a pentagonal block. I have managed to get things to co-operate today so I may just rebuild the van from scratch to see if that helps. The motivation to use the spline and not a vertex object is that I will be animating this and want to keep everything as clean and simple as possible. Thats one of the reasons I am mapping the textures rather than building them into the geometry. Cheers everyone

How are you generating your shape? Mine maps correctly. I have seen this though in other instances, especially when mapping a preexisting texture on to vertex object. It can usually be correct by setting the top of the shader tree to Parametric mapping>flat mapping>check ignore normals>select the full cube. Mark
