I created a custom material function. For troubleshooting purposes, I want to paste some of the material nodes into another material to play with them. When I try to save it, I get a “Graph is linked to object(s) in external map.” Error.
Here’s the full error:
Can’t save …/…/…/…/…/…/Users/Trev/Documents/Unreal Projects/prj_lamplight_alpha_01/Content/Materials/Material_Functions/NewMaterial.uasset: Graph is linked to object(s) in external map.
External Object(s):
/Engine/Transient
Try to find the chain of references to that object (may take some time)?
I am investigating this issue, but have some questions. Can you reproduce this error in a new asset or project? If so, what are the exact steps that you take? Can you attach you log files as well? They are located in the [PROJECTNAME]/Saved/Logs folder. Any additional information may help.
If I may clarify one thing, the material function you are copying from is it located in the Engine or Game directory in content? And, if possible could you give us a screenshot of the original Material Function nodes?
Hi, I just encountered the same issue.
But I found out what was giving the problem. It’s not the the copied nodes but the copied comment boxes that give the error.
Btw I’m currently using 4.5. Haven’t tried it in 4.6.
(just posting this so you can reproduce this error more focused, and for other people who are having the same issue. )
So to bypass this. Just copy what you want but after copying delete comment boxes and make new ones.
