I've been looking for some tutorials on welding tubes in ZBrush. Is it just a basic mesh joining two pieces, and that basic mesh just gets manipulated like a welding tube?
Flourescent tubes are not completely transparent, they are coated on the inside with a paint that reacts to the mercury. It's a milky white so you could just make them opaque. Burnt out tubes will usually have darkening on the ends of the tubes.
umm, you could just get the train fordy, then the tube. can't see the point in driving there. anyone tubing it should get an oyster card. damn sight cheaper. Its 4.50 for a single tube journey these days
