I've imported some images into trackmaina, converted them to textures and applied them to custom blocks. When trying to save the map following message shows:


How do I fix this problem?

Dont use custom textures on your custom blocs.

What Teroor said. Other people will not be able to load the map, as Trackmania doesn't allow for texture embedding - only geometries using the standard textures are allowed.

You can however consider using a texture mod for your map to change some surfaces.

Is there maybe a forum post on how to create a texture mod? Would be very helpful, thanks

There's a post here that explains how to apply texture mods to a map:

At the bottom of the post is a link to the default textures. Basically you just modify them with an image editing program and resave them into a zip with the same filenames. That should work as far as I know. You'll need to set up a locator too, just like you do with signs.

Okay, thanks for the help guys
