Как исправить ошибки в ContentManager

[cronos]

Здравствуйте! Устанавливал объекты в Trainz2009, большая часть установилась но у некоторых выскочили следующие ошибки:

Warning: The file 'flower.lm' is provided in LM format despite containing only a single mesh. This may have a negative impact on performance.

Warning: The file 'flower.lm' is provided in LM format despite having no attachment points and no animation support. This may have a negative impact on performance.

Warning: The file 'flower.lm' is provided in LM format, however the high-detail mesh is comprised of less than 300 polygons. This may have a negative impact on performance.

Подскажите пожалуйста как их поправить?
