I need help with Transparent Tiles

This is what my tiled map is suppose to look like.

This is what it ended up looking like. I am using MonoGame. The transparent parts are replaced with black.

This is a question best asked in the MonoGame community.

In Tiled, does the transparency come from the image (an alpha channel), or did you set a transparency color (so it’s black or some other solid colour in the original image)? If it’s the latter, you need to look into how to do the same thing to the loaded texture in MonoGame.

If it’s the former (the image has an alpha channel and it’s not working), then you need to make sure you’re loading that channel (see the parameters on the methods to load the texture), and that you’re using alpha blending when you’re rendering the tiles.
