Thank You

Hey Hell-o -

Let’s try this solution first, go into your project’s directory and delete the Intermediate and derived Data Cache sub Folders if they are there then open your project and try to open the material editor again.

Let me know -

Hey Hell-o -

I have not heard of any major problems with the Material Editor crashing the editor recently and haven’t been able to reproduce this issue. Two things, can you send me your project zipped up so I can test it internally. Second, I would uninstall and reinstall your editor if you are running from the launcher or recompile if you are building from source.

Thank You

I don’t think its so easy because I see on logs problems with compiling shader and and other problems.

The project its just the default project nothing special and it result that is 650 mb how its possible ?
Did you read the logs ?

Hey Hell-o -

It is the starter content assets in the content sub folders that cause the project to be so large. Yes, we did look through the logs and can tell you that it is a crash regarding a particular shader compilation but without being able to reproduce the crash internally I cannot identify where that shader compilation directly occurs.

Thank You

Hey Hell-o -

Upload the 650MB zip file to a Dropbox and post a link here and I can then I will debug the project. If there is a time constraint for you to get the engine up and running I would absolutely suggest uninstalling and re-installing the engine from your account page.

Thank You

Ok I will do it.

Hi Eric I upload my project to dropbox and here is the link.

I will wait for a response.

Hey Hell-o -

I downloaded your project and nothing was a miss for me. I was able to open the material editor without any crashing. This means that the issue must reside in your installation of the engine. I would go into the Launcher and the library and then verify the install by right click on the engine number and verify. After that see if you can open the Material Editor.

Thank You
