So as not to throw this topic off subject, can you please post a new topic in Ace support with the following information: The specific image sheets you are trying to import and a screenshot of the error message? Thanks.
@ Kazzador I've used some of your sprites in a free game called "The End of Warren's House" you can find and download or try at www.nbgstudio.com/en/
This is for credit your amazing work! Thank you so much!
