Hello everyone,
Iām having trouble with a simple texture :

Nothing out of the ordinary (at least, not to me
). However, in the editor and whene rendered, it is black :
Notice that everything in this zone is purely black (except some parts of the automatic lawn mower) ā¦
Preview with a spot at max strength (1000) :

The file is a DAE exported from Cinema4D (originally from vectorworks)
Any help would be appreciated !
