Glad you are enjoying it :)
Do you mean somethings like this? It's the template I use for my 47-tilesets.
here's a actual pixel scale version of it.
if this is not what you meant, do let me know what you meant and I'll try and create it :)
Something like that, yes! I assume the template for an artist creating one is slightly different to a developer using one - but I am a beginner at autotiling, so I am not sure. I am mostly familiar with the drawn in bitmasks in the tilesets. Something like this.
But I think I will figure it out. Thank you! :)
