34:10 sometimes you don't need 2 image files. A transparent png contains color data which will be black and white without transparency and it also contains an alpha channel which is again just black and white data used to define transparency like a mask.
15:43 working at real world scale has benefits. Light falloff matches the real world, you can use addons that allow light power to be set in Lumens and use real world light values.
18:50 the orthographic view was not centered on the bottle so the camera will not be centered on the bottle. Alt+G to center the camera object at the world origin and then pull it straight back to have a perfectly centered camera looking at the bottle.
I have a quick question. If I want my logo to appear on a bottle with more color instead of just black or white, what should I do? Currently, it is only showing up as white on the bottle.
Hey man just wanted to say thanks a ton! Your vid is so easy to follow and I'm super happy with my results! Looking forward to more videos in the future! Cheers
