ok hehe! Personally I didn’t quit my current job to learn cg. I’ve been learning by myself for about 2 years now. I have lot of free time so that might help.
Do you want to do arch-viz only for realtime interactive stuff or you are ok doing traditional rendering with vray/corona for exemple? I’m planning to offer HQ stills made with Corona Renderer and movies/rt/vr made with Unreal, preferably. But my portfolio is going to be 95% Unreal stuff actually because it sucks going back offline after you’ve touched unreal tbh.
