I package a game, and than com this fatal error massage??? can everthing help?

D:\Build++UE4+Release-4.18+Compile\Sync\Engine\Source\Runtime\Engine\Private\Materials\MaterialExpressions.cpp is that material compatible with 4.18?

What does the log file show before that line? Is there a reference to the offending material? Did you try to delete it and re-create it?

Looks like an issue with one of your materials. We need few more lines before that one to identify it. The log should name which material has an issue. Very likely if you open it you will note a compilation error / an invalid node.

This is the complet log file…thx for your help. I crate this project with datasmith

Have a look at this material (or is it a mesh?):

Content\3dsky/mercedes/Geometries/26

Can you see anything strange with it?

8

is a mesh. e wood frame with a pictures…looks everthing good! i have importet with datasmith and 6 othe frame…should i delete this mesh?

9

ok, I will use it like that. I thank you very much for the help

I am not sure it is exactly that mesh, but if you did a backup copy of your project you can start to delete assets one by one (or in groups) until you find what causes problems. Start with that one.

11

So did it work by deleting that mesh?

12

I deleted the whole group, it did not work. it is to despair

Keep deleting until you find the culprit. Then you know which one it is.
