you’ve got all the text penetrating into the base object most of the text either penetrates itself or it’s neighboring text (overlaps) by a bit and you’re telling it to close holes. It may be one object but it’s made of 10 pieces in the one object and all embedded into the base and others to some degree (try selecting a point or poly and doing a Select Connected). Optimize and Close Holes is going to have a hard time getting it right in those conditions and I can’t see why it would be necessary, there are no holes in your objects (that I can see on a quick look) you just have 10 objects (pieces) where there should be one.
How you want it to break should determine what the construction should be it should be. Do you want it as one object or should the text be separate? Given it’s chocolate I would think all one object but with the different colors in the render it would depend on how the ‘chocolate’ was made.
And what about the nuts? In the example file the nut cloners are all deactivated but assuming you want nuts there too…
– why not only one cloner, just increase the count and keep the nuts from occupying the same space with a Push Apart effector, the Random effector isn’t necessary, I think, as the Surface distribution of the cloner is already random. The problem right now is since the letters are still whole objects the nuts are covering all the hidden areas of the letters too so you are loosing many of the nuts inside the chocolate. That would be fixed if it really was one object.
I just tried to turn this all into one object (minus the nuts) and it wasn’t successful even when I took all the letters of each word and Unioned them then all those and unioned with the the base. I suspect it’s because the words have overlaps in the corners of the bevels – and more testing, that seems to be true. Back in the original version try re-filleting the caps but use Constrained so the tight corners in the text can’t fillet ‘over itself’. That gives limits to the amount of fillet you can have but it’s a lot cleaner construction with script fonts like that.
