Overview - CRYENGINE 5.4.0 Preview 7

We are very pleased to bring you the 5.4.0 Preview 7 release. Great progress has been made and as you will notice there are no known issues in the Preview 7 Release. We could not have gotten this far without the support of our great community, so once again a massive thank you for all your feedback, please keep it coming (but through the normal channels please).

Entity Components

To help the community get to grips with the newly introduced Entity Components feature our Developers have written some Entity Component Use Case documentation. CRYENGINE users may be particularly interested in the two Advanced Use Cases that show how different Components can be combined to create some great effects. This documentation will be expanded on over the coming months, so keep your eyes peeled for further updates. 

Project Launcher Tools

Also in this Preview Release, we bring you updated documentation for the Project Launcher Tools.
