The Cpp-UE-Get-Thumbnails plugin is designed for Unreal Engine 5.2 and above. It enables users to save thumbnails of assets in the content browser to .png files by automatically creating a folder named "Thumbnails" in the project directory.
- Go to "CPP-UE-GetThumbnails\Content\Python" and run "InstallRembg.py".
- Make sure you have Python installed on your system to be able to use the above script.
- Rembg is necessary to remove the background of the extracted thumnail images. If not installed, the extracted thumbnail images will have the default Unreal Engine checkered background.
- Download the latest release from the GitHub repository.
- Unzip the contents of the zip file.
- Remove the "-main" text from the unzipped plugin folder name at the end if its there and if not then leave it as is.
- Go to your Unreal Engine project directory and look for "Plugins" folder. If there is none then make one.
- Copy and paste the unzipped plugin folder into the Plugins folder of your Unreal Engine project.
- If its a "Only Blueprints" project then directly open the project. You will see a pop up asking you if you want to build "CPP-UE-GetThumbnails". Select "Yes" and continue.
- If its a C++ project then follow the same process. If "Build from Source" error is shown then make sure to delete (Saved + Intermediate + .sln file + Binaries), then generate solution from the .uproject file for your project and open the project. If problem still persists then look into your project's C++ code for errors. If still not fixed, then you might have to do some research on your own since its a common problem in Unreal.
- Once the project is open enable the plugin (Plugin Name is "GetThumbnails" inside Unreal Engine) from the Plugins menu if not enabled already.
- Below is a tutorial video for you but I suggest you stick with the README file as its the most updated and contains all the necessary steps in depth.
