I need a bit of advice on using the image input on the k3d object renderer patch. I am trying to texture live video onto the faces of simple, low poly 3d objects (a pyramid for instance), of which I have modelled and loaded into the patch. Essentially I want to end up with the "front image","Left Image" type schema for the built in primitives but using my own models. When I feed the input an image it looks like it is just using a single pixel from the video as it just comes out as a solid colour. No amount of image resizing etc seems to change this. Is it because the faces are single polygons? My models are at 1,1,1 scale in the loader, and I can't seem to texture it in a manageable way. Help would be really appreciated. :)
