The documentation is outdated, and hard to follow, the links to the pictures in the documents are broken.
There are very few tutorials and were made years ago. It seems there is a small user base.
The UI is confusing and frustrating. In order to create autotiles I have to open a new tileset in another tab, and click on the terrain sets icon to convert to terrain sets. I mean can I just convert the tileset to terrain set on the same window that has my tileset loaded? It took me a while to figure that out.
In order to set up autotiles for a block of tiles, I have to add terrain set then add terrain then mark the tiles as corner or edge or mixed then name each terrain then add the image to the terrain. To add the image is also not straight forward, need to right-click the tileset and then chose the option to add it. Then repeats all the steps above for other tiles. Even once I got all the tileset setup there is no guarantee the autotiles work correctly. That is tedious and hard to do already.
To erase the markers, there is a small button on the right corner name “erase terrain” need to click on that button. I mean, why can the button on the top toolbar, why is it on the very far right corner near the smaller button “delete terrain”? I thought “delete terrain” and “erase terrain” are the same. Took me a while to figure that out, they are not.
I spent 3 days using it and I could not get autotiles working properly so I gave up. The version I was using is 1.9.
I am not sure if you have used RPG maker before, it is the best tile map editor I have used besides layer and tilesets limitations. if you bought the maker it comes with the autotiles setup for you. To use different tiles is also simple, use any graphic editing tool and place the tiles in arrangements based on the template then import the tiles to the maker. Super easy, no need to setup anything. There is also a lot of tutorials out there. I think Rpgmaker’s tilemap editor is the best selling point of the maker. I enjoyed drawing houses, forests, landscapes…etc with it. I am sure a lot of people do.
