A crash is occurring when adding an empty shader directory when using the custom node within the material editor. This crash is preventing some users from opening their projects that use this workflow to create custom shaders.
This is a regression from the previous version of the editor.
4.16.2-3514769: Does not occur
4.17 Preview 1-3528061: Crash occurs
//UE4/Release-4.17-3535404: Crash occurs
1. Create new blank project
2. Create new material
3. Add Custom Node.
4. Add the following: #include "" return0;
5. Plug into Base Color
Outcome Crash occurs shortly after entering the text and compiling the shader
Expected The editor produces a compile error message like in previous versions (see image attached)
