As I see the dev in the forum.
On Mainpicture:
*I can recommend him(or her) to crank down the resolution-level on all the characters(since it's not close-up image). Especially Hair figures, hair is a very big memorydump and timeconsuming for GPU.
*Put a Postdenoiser around 2350(min Samples: 2500)
General Tips:
*Everything behind camera(if there is any), hide them already in viewport(so it won't be rendered), GPU needs to cache these objects, still if they're not visible in the render. For example, BJ-Scene on the toilet. Is MC's hair visible in the scene? Hide it..
*Take some learning lessons about ghost lightning and shaders
I hope some are tips, others might be not.
Otherwise, seems quite promising this far.
Waaay too early for a review though, and that wouldn't be fair for the game , but it's a start.
Keep it up!
