How to update the tileset image without messing everything up?

Questions

Hi!

I have a tileset image:

image1011×818 80 KB

For perf optimization purpose, I decide to “crop” the source image (I made sure that all the tile I used was in the top part… so my map would not be impacted)

But white tiles are still displayed in the tileset

There is a “columns” field but nothing about the rows.

What should I do?

Thanks
Rag

The white tiles are just placeholders, in case you want to delete those tiles from your maps or copy+paste some properties, or in case the resize was temporary, so that the data associated with those tiles isn’t just immediately lost.
The white tiles will go away when the tileset is reloaded, e.g. when you restart Tiled.

The white tiles did not go away after I restarted Tiled.

I’m not sure, but that could mean those tiles are still in use by some map(s) or contain some additional data (terrains, custom properties, collisions, animations, etc).

Thanks for the reply. The white tiles won’t go away no matter what I do. So I just created a new tileset with the same tile image…
