Unfortunately LE forum terms of use is not allowing to post any example that is coming from other engines. I can post my own screenshots using other engines, but I am afraid that is also against the mentioned terms. Also, I will not suggest you to give other engines a try to prove my point, but the fact is, in my opinion, that post fx needs more work in LE. You have full right to not agree with me, I am just posting opinion based on my personal experience. I am also supporting the work of Josh and I really love LE, but that doesn't prove the fact that some things could be even better in LE
