heyas; the problem is, you can't copy the main node. (at least, mine doesnt!!) what i've been doing is doing the texture on the main material, then saving it to a temporary libray. then grab the next material i want to apply it to, and double clicking the mat. and so on, and so forth. i've built a 'sequins' mat that i want to chop so it won't override your other colour and whatnot nodes, but will only insert itself where it's connected. but i haven't gotten to that yet. the idea of the sequins is you can apply sequins to your dress texture, your sweater texture, your cat's fur... anything. :)
