TwistyKanecoI didn't find any other more relevant Lawena thread so I'm bumping this one.
I've recently asked Quantic (lawena's dev) to add HLAE support as I've been using it A LOT for smooths. I've been testing the last few days with him. And it seems to be working fine so Lawena now fully supports HLAE, smoothing tf2 shots has never been easier!! This will make my workflow so much better for the play of the day series and i55 fragmovie, I really can't thank him enough. Big ups to him!
It's still only available in the preview branch of lawena but I assume it will be coming out to the public version soon since our tests went fine.
I might make a tutorial soon on how to smooth with HLAE and also share my HLAE configs when I have some free time.
I really hope to see that guide at some point, I love you work
I definitely second this, I've always wanted to try using HLAE but the workflow seemed too complicated to learn
