How do I fix mask collision?

Hi, I can't set up a collision mask for my project. The problem is that when testing, the sprite does not see some points of collision. Help solve this issue.

Not exactly sure what's going on here, but you might have better luck breaking up your collision polygon into multiple simpler objects. Collisions with complex concave shapes have a reputation for having issues. In general you probably want to avoid having such a large sprite object to begin with.

Solved the problem: initially the sprite was 13000 pi. Divided the track into equal parts in Photoshop, up to 4000 pixels. I added physics and a collision mask to each sprite. During testing, it is processed normally.

Thank you for answering.

By the way, I made a tile background with the same collision polygon - physics was not processed anyway.
