80-100 per render? No offense, but a whole AAA game costs 15 dollars after a year on steam.
And a whole AAA-game is sold millions of times. For example Cyberpunk 2077 cost 60$ at release and was immediately sold 8Mio times. That were 480Mio $.
Compare this here with a photographer. The cheapest service in a photo studio are passport photos with a price range of 15 to 30$. Job application photos can be had for 50 to 100$, and for a professional shoot you should plan on around 80 to 250$. When I got married many many many years ago we made an extra wedding album with 10 professional studio photos - price was at that time 1200$ (I should have made a divorce album, too) in addition to the normal photos a cousin (who is a hobby photographer) made of the whole day long. I think now you'll pay more. That here is more like a professsional shoot and no passport or job application photo.
Maybe the workflow how I make ONE render/scene helps a little to understand the work you have to do :
- 10-15 minutes Drawing a quick sketch/thumbnail to get an idea of a starting point for composition/making notes on colors and lighting
- 15-30 minutes roughly designing the scene - Use some general shapes, like spheres, rectangles etc. as placeholders for the future models and light it roughly out.
- 3-4 hours Replace the general parts, floor, walls, furniture etc and fine tune that until I'm satisfied with the empty scene.
- 10-30 minutes Looking through content for characters, clothing and scene filler items like billboard chars, flowers, clutter etc.
- 60 minutes/character placing and posing characters/content, adjustments/fixes
- 45 minutes Adding to the basic lighting, effects and adjusting materials (incl. short test render to see the light working)
- 2-8 hours Finalizing lighting and rendering (and rendering blocks for me the PC for any other work, because of the shitty GPU, could be faster with a better GPU, like a RTX3080)
- 1-2 hours Post-work like denoising, overlays (photoshop, gimp, etc. ) converting from png
The game contains over 1000 of that
and that workflow does not include coding the VN, writing the story, testing, making your own textures, materials, content objects etc. Sure not every pic take the time because you will reuse a scene like the characters rooms, workplaces etc. and just change the poses, some lights etc, but rendering will take the same time. If you use a rendering queue it is possible you can have the PC render a few pics in a night when you sleep, but think of an animation - that will need minimal 10pics per second (30 are better if you want it smooth) and following that 10sec will be 100 renders you need to make.
