Hi!
I just wanted to know if there is any significant cpu or storage overhead if I trim my sprites before adding to Unity and creating Sprite Collections of them.
I have scenes with maybe 100 sprites, also running sprite animations. The majority of them are (when trimmed) only 100-300 pixels high/wide. Without trimming the transparency, all of them are 1024x768.
Development target is iPad 2+.
It takes me a little time to pre-trim them, so using the automatic trimming in 2dtk is prefferable. Unless the runtime un-trimming is performance heavy?
Thanks in advance

There is no cost at all for runtime untrimming, if anything it will be faster as the transparent pixels won't need to be drawn.

OK so from now on I can just forget about trimming sprites in photoshop and instead just let them get trimmed automatically by 2dtk...
Although it increases source sprites' sizes a lot, I guess it is okay since only the trimmed sprite atlas is baked into binary
Thanks for your reply
