Ive noticed that traditional artists don't seem to respect 3D because once it is created it can easily be re-created, it isnt as uniqe or one of a time, which is kinda true except that they forget that the initial model has to be created from scratch.
My Mother is a painter and when i used to talk about 3D work i was constantly having to explain that it is much harder than it seems. Fortunatley dissapearing for hours at a time and constantly getting critique made her realise that it is hard.
I reccomend just reminding people that it is hard everytime it is brought up untill they just ignore you and pretend to agree.
