Issue comments

When possible, attach your MCreator workspace (or even better a minimal example workspace required to reproduce the bug), game logs (full logs, do not crop them, in text format, not screenshots of logs) from the Console tab or terminal and steps to reproduce the bug in your workspace. If logs are long, use service such as Pastebin to host the log and provide the link to the log from the ticket. Please specify which mod elements to check in your workspace too, if applicable.

Thanks for the quick response Klemen! Here's a link to my example workspace…

- In the test environment you can find the issue by pressing the K key bind (OpenMenu in workspace) to open the SheetsStats gui or by right clicking the Scroll item (ScrollBlank in workspace) to open the ScrollItemGui, this will almost immediately crash the game.

Additionally, heres the pastebin link to me crash report

Thank you for your time and help! 


Thanks for the response crispy_chips! I checked your link however it seems that relates to Gui's with inventories and slots and sadly mine does not contain any of those, just images, buttons and text labels.

Thanks for your time anyway!

Minecraft 1.14.4 only allows lowercase English alphabet letters, numbers 0-9 and /._- characters. If the texture file contains other characters such as whitespace in your mod, this will cause the Minecraft to crash. This rule applies to:

  • texture names
  • sound names
  • structure names
  • model and model part names
  • tag names

If this error happens to you, check the error log to see which resource is causing this problem/crash. You can go to Workspace tab -> Resouces -> Textures and check for the textures marked with a yellow exclamation mark. These textures have been detected to have invalid names by MCreator and you need to rename these.

To rename these, go to the <workspace folder>/textures and rename all problematic textures there.

After you rename them in the textures folder, make sure to reselect these textures in the mod elements and texture mappings that use them as the mod elements still refer to the texture file names with invalid characters in their file names and until you do this, the game will still crash.

Thanks crispy_chips! It seemed my texture name had a capital in it which was causing the game to crash whenever I opened a gui, Simply renaming this texture was enough to fix the issue, false alarm everyone.


Thank's for both of your help Klemen and crispy_chips, have a great day!
