I just figured somthing out…If you render a scene (F12) and then move your mouse over it and press “Z” it zooms in on your render so you can look at tiny details. It is usualy a little blocky however… I bet tons of people know this and I’m posting old news…But it’s new to me and I be a few people don’t know about it
I guess I’m one of the ‘tons’ lol but yeah, that’s pretty neat. It would be better, if the render was vector graphics! haha
I think the + and - work also to zoom in and out of renders/imagemaps and a few other places I think?
Clicking/holding the LMB gives you the R,G,B,A values at the curser location.
And… using [J] you can switch between your current render and your previous one!
You can scroll through a rendered animation with the cursor over the render window and LMB, after pressing play.
i believe you can use the numpad(?) to go forward and backward, etc. in an animation too
