I’m working on a project and would like to use the point light shadow renderer but I can not find the class in the SDK. I saw the different shadow types here https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:advanced:light_and_shadow but I can’t use any of them except the pssm and basic shadow renderers. Is there a plugin or library I needst to install?
No. You just need to create a basic game project and start using them. You will see a few demonstrations of them in action if you create a JmeTests project and go to jmetest.post source package.
