I made fire extinguisher and added to Barstow and burnside for my DerbyPack but it doesn't appear in game! it says Failed to get render mesh fireexhaust Who knows how to fix this? I will send you a file thx! I'm not sure this is a same problem on my super kart or not.
are you sure the mesh name is exactly the same? if jbeam points to a not existing mesh it produce this error. you put your dae in common?
if you want to use one dae for two vehicle you need to put it in common, else you need to duplicated it to each vehicle folder also in the log there should be a list of mesh that are loaded/available, extinguisher should be in this list if you things correctly (if it work the list may not be printed again)
