PAFPAF: Last night I used Source Filmmaker for the first time - this is what came out.
Scene and Model from sfmlab.com.
Also their tutorials helped a lot to get started.
Ass slap-sound ripped from random xhamster pr0n.
Encoded/watermarked using ffmpeg in VP9 (video) / Opus (audio), old/or shitty-browsers may not play this file properly because they lack codec-support.

enjoy ... or rant/hate/troll/whatever

Master69: could of left the "OWW!" out XD
Otherwise this was alright for your first attempt at SFM, good work :)

Anonymous¹: sound is awkward but other than that not too bad, lighting could be better too.

Bloodsun: Not too shabby, though the 'OWW' was not really needed.

Renegade: Cringe
