Hello I am trying to zoom in on an object to texture paint the inside of the mouth of a person but at some point the zooming in function stops and I am not sure how to continue zooming in. Sometimes it works good other times it doesn’t. How do I fix this please?
Thanks,
High there !
You can define a focus by pressing alt+MMB. Then try zooming in. If that doesnt work, there is another way to get closer to objects. Instead of using mousewheel, if you use ctrl+MMB and drag, you will have a smooth zoom… that won’t solve the issue of max zoom… HOWEVER 
if you press shift at the same time, you can go as far as you wish
