Error message loading the map

Hello,

I have a message error when i load a map

failed to create ressource(is the file missing?)
levels/namemap/art/shapes/trees/defaulttree.dae

what does it mean ? How can i fix it ?

 

Is this with every map or one map in particular? If it happens on one map in particular then can you specify what map it is?

 

it's my custom map made with the developer mod .
Only this one yes other works

 

It just means you're missing the file for "defaultree". Just find it in another map and copy the file over to yours.

 

thanks for your answer i keep searching this file
