why is this the excuse for every creator that makes up bullshit for why they keep dragging out releases?
it's more believable that porn creators ripping off IPs to make money are liars than all of them are "perfectionists"
Well not to defend Wildeer specifically (because he really needs to get his priorities straight, like Lara in Trouble should not have gotten up to 8 parts while Gatekeeper stayed at 2 for so long), but there is a lot of things that go into a render. Still shots alone can take hours to cook depending on the settings. Animations even longer. And its not like a couple extra hours, its exponential, days even. And it also slows the shit out of your computer since it takes so much processing power. Add on extra factors like the program crashing, or something being out of place in the render that you didn't notice, and you can start to see why some things take so long.
Liquid physics, hair physics, clothing physics, its all shit you have to account for, the program isn't just gonna move everything naturally for you. Its often why some animators don't even bother with things like hair physics, just having them solid and never moving. Its why some animators just strip clothes off immediately before sex, because they don't want to deal with it. And liquid physics have caused more delays than anything else.
If you've got the hardware, I'd encourage trying blender for yourself. Grab some models from Smutbase and just play around, see how much goes into just setting up a single pose, and you'll gain valuable perspective on the time investment these artists have to make.
