I'm animating pixelart, when the frames get imported into the library, they're all blurry, so I have to right-click them, go to "properties" and uncheck "allow smoothing"
Now, doing that for every frame of every character and animated object feels like rolling a boulder up a mountain, and draws majorly from my motivation, is there a way to make the "allow smoothing" box unchecked by default? or at least mass-unsmooth my imported frames?
You set the allow smoothing in the Library. In there you can select all of the bitmaps, and click the i button to set their common settings. You could set them to be lossless at the same time as unchecking the allow smoothing, for all of them in one go.
As a point of historical interest, Allow Smoothing used to be unchecked by default, and it was terrible. Many accidentally pixelated photos resulted from this.
