Is this a bug or am I doing something wrong? (Transparency Issue)

[Mike]

So, I've been working on some tilesets for a while. Started building a map with my new tilesets, and am running into this issue.

 

Best explained with the attached image, but I am setting the background completely transparent, and exporting from gimp as a png.

 

Looks fine previewing the image of the tileset, but when I use it in the editor, all of the transparent spots appear black, and show up when I lay the tile down. This is especially troubling when trying to, as in the example below, add something smaller than 32x32 on top of an existing tile. Everything that is supposed to be transparent is black. 

 

Is there a solution to this that I am overlooking, or will I have to fill every pixel of a 32x32 grid with whatever I want adjoining?

You're using everything on the lowest layer possible, tiles you wish to render above other tiles put on the layer above the previous. Currently you have everything on the ground layer, keep your sand tiles on the ground layer and transfer your dirt transition tiles to the mask layer.

Wow. I feel kind of stupid that I didn't think of that. Thank you

Don't feel stupid, we all started somewhere  Intersect has a steep learning curve, we get questions from both advanced users who have been making similar MMO makers for years and newbies!
