I am making a car at the moment with subsurfaces. So far I have no triangles in it at all.
Trouble is, modelling like this is hard work. :-?
Question 1. Is it safe to subdivide mesh occasionally (producing triangles) or should I avoid it all costs?
Question 2. If I do have triangles and I do a test-render and see no artefacts, does this mean I got away with it - or can artefacts appear without warning later on in future renderings?
The reason for question 2 is that I am thinking of using an external renderer like Lightflow later on and I don’t want to have to redo meshes later on if I can avoid it.
Any advice on this gratefully received.
