Short description of error
If the material of an object has texture coordinates using another object when the collection is instantiated the material does not update the coordinate according to the location of the instance. The texture coordinate remains where the object is in the collection.
Exact steps for others to reproduce the error
1 create a collection
2 create an object
3 apply a material with a texture whose coordinates are obtained by means of the "texture coordinate" node
4 an empty object is created and chosen as an object in the "texture coordinate" node of the previous object
5 an instance of the collection is created
6 when moving the instance the coordinate based on the second object is not updated according to the position of this object within the instance, it remains where the original object of the collection is.
