Foliage Creator script

[Dickieboy]

I've been mucking around redoing some of the foliage on my map, and using this script. I'm noticing an odd thing, that the foliage I'm getting is "shifted" or offset to where I'm actually painting by what appears to be a single pixel. 

This is the masked area,

I run the script and it puts grass here


You can see on the left that it appears to be outside the masked area, but on the right edge it seems to have respected it better. 

Now If I then run a different "creator" to remove the foliage from the areas covered by the indoor mask, you'll see it's shifted even more.
Before

After

You can see that none of the grass on the bottom left has been removed (where I'd have expected it to be, but the top right edge has been removed outside of the masked area. 

Any ideas?

Could just be the way that the foliage is painted by giants Editor, like the texture paint it never paints exactly where you want it.

The only other suggestion is to ask on the creators forum
