First of all, sorry English is not my native language
I have some problem with Tiled Map Editor and Monogame.
I use TiledSharp to integrate my tiles into my project Monogame but the offset is not respected.
We can’t help you if you don’t share your code. TiledSharp only does importing so most likely this is a bug in your rendering code. There’s a MonoGame sample project for using TiledSharp which might help you out over here: https://github.com/Temeez/TiledSharp-MonoGame-Example
An alternative is to use MonoGame.Extended’s support for Tiled maps. It handles rendering for you. I think there’s a NuGet package specifically for the Tiled classes.
