jME 3.10.0-alpha3 Available for Testing

Thanks for testing and reporting this. Should be fixed with the PR I submitted, so I’ll try to get a new alpha out sometime in the next week with the fix (along with the new changes to PointLight and SpotLight that I mentioned). Another important thing to note: The change to use SinglePass (instead of the previously default MultiPass technique) changes Lighting.j3md to use a different fragment shader (SPLighting.frag instead of Lighting.frag) and the exception you found with fog actually has been there for years now, but I’m assuming not many jME users ever used that shader with Single Pass (considering Multi Pass was the default), so I assume SPLighting.frag may be prone to more bugs considering how little usage its gotten over the years. I also only use PBRLighting in my projects and haven’t used Lighting.j3md in quite a long time, so I won’t be much help testing these changes past running the tests/examples (which are limited in the scope of what they can test compared to testing in a real project) So I encourage anyone who does still use on old non-pbr shader to double check your scenes with the SinglePass technique and ensure that nothing looks wrong.
