You're right, I feel like an idiot. I stayed up all night playing with Sprytile so my brain must be fried, sorry! I had it set on the Standard shader with the UV map set for albedo but the rendering mode was set to fade. I've set it to opaque and it works mostly great, with the exception that it did something weird to the transparent tiles (the image on the left is before, on the right is after). I'll keep playing around with it within Unity and figure it out, thanks so much!
