Need help editing stage.

[JordRB]

I was trying to turn the Mushroomy Kingdom (1-1) stage into a Toy Time Galaxy stage. I worked hard on making the textures (mostly from scratch) for it. The problem I have is all the white stuff here. V

I left the textures for these things blank, hoping it would make them transparent. I event went and deleted the polygons for those things. But I still get those white hills. Is there anything I can do to get rid of them?

Just bumping this up. Still would like some help with this.

You'd probably need to vertex them or something, only certain textures can be made transparent. There's a way to tell which can, but I can't help you there.
