Errors

Ocassionally there are some error messages caused by the game or some mods. The list is a compilation of known error messages and possible solutions. The list does not include all possible error messages.

Missing resources

X resource file(s) are missing: res/…	some resources are missing (removed mod?) and can't be covered by the fallback mechanism	restore or replace missing files
c:\build\tpf2_steam\src\lib\util\filesystem.cpp:316: FileSystem::AddArchive([…]): Assertion `it→second.archiveId < 0' failed.	the models.zip archive in /res/models/ is missing	validate game files

Models

Error Description	Potentially caused by	Possible Solution	External information
Group […] has 1 materials but mesh has 3 groups	missing values in the mdl definition of a model part	add missing material references	thread (german)
Key:type invalid material type: […]	material uses deprecated material type	change material to supported type
c:\build\tpf2_steam\src\lib\model\metadatamap.h:26: […] : Assertion `it != m_key2value.end()' failed.	Some configuration entry in metadata is missing	add the missing config value

Scripts

Error Description	Potentially caused by	Possible Solution	External information
attempt to call upvalue 'scale' (a number value)	coding mistake in lua script	?	?
attempt to get length of local “ff” (a nil value)	coding mistake in lua script	?	?
attempt to call field 'rotX' (a nil value)	coding mistake in lua script	?	?
creating globals by assignment is not allowed (variable was […] ) Did you forget to add 'local' before your variable?	global variables are not allowed	add 'local' before the variable
Assertion 'it→second.second == 1' failed	a snapNode has more than one edge beginning or ending at its position	make sure that only one edge is at that node.

Terrain Calculation

Error Description	Potentially caused by	Possible Solution	External information

Vehicles

Error Description	Potentially caused by	Possible Solution
railVehicle/configs/axles: mesh […] does not exist this error is usually caused by modding	the mdl has a defect axle config entry that points to a mesh that is not part of the vehicle	fix the mdl config reference
