Spritesheet Sprite Pivot throwing sprite grid off on export.

[K7S]

Hello,
I am trying to export a spritesheet from a movieclip/object, and the preview looks great in animate cc;

However, the sprite pivot / anchor looks off. The grid is asymmetrical. Which makes it unreadable in any other program so far as I know. It looks like it is trying to account for the cropping fromthe top left. I thought this might be due to the movieclip's anchor registration but I can confirm it is set to the center. And the animation is also center stage.

And so when importing the sprite into Unity the animation's position is offset incorrectly due to the way the sprite is rendered ;

I thought that sprites normally have a sprite pivot that is centered, like this;

This symmetrical grid produces a fluid animation in any other program.

I added a bounding box to the heart animation just to see where things are going wrong when it auto-crops the spritesheet and I believe the problem arises from this uneven extra pixel spacing around the borders of the object; 

No matter what option I change in the exporting options, I can't seem to get an even, symetrical grid. I've tried every single feature in the exporting options now. Has anyone had this problem before?

Why won't it export with a symetrical grid? Is animate cc the right tool for this?

Thanks for your time

Did you try slicing the spritesheet with the XML file Animate generates?

No, can you point me to some information about that?

I found a free script for Unity that does that: https://youtu.be/9diGiz0x040

But the surest way is probably Texture Packer:

Thank you, I was looking at this too.

Is the spritesheet feature one of those quietly depreciated features in animate CC? I've never really used it before until now.

I thought that the MaxRects setting would give perfect bounding boxes but I can't seem to find a solution within animate. Seems like it's just in reach though

It definitely needs some attention; would be nice to have a grid algorithm among other things. You can request new features from this link:  https://www.adobe.com/products/wishform.html

So this tutorial is a couple of years old but should be of some help.

Thank you guys

Where you are to get it figured out?

Hi Nick, No answer within Animate CC yet, I had someone on my team build a script for my png exports from animate. So a bit of a workaround. The spritesheet feature inAnimate looks well developed and what i'm asking for here seems like it's just in reach. Maybe they will put it in the next update if we submit a request.
