Yeah, you do have to be careful with what your PC can handle. What I used to do when I had an older video card (a 1050TI with only 4G VRAM at the time, I now have a 3060 with 12G which is MUCH better, more video card memory is VITAL) is I would hide EVERYTHING that was not visible, and I mean EVERYTHING... if the far part of an arm of a character was not visible to the camera, I would hide it. What happens is when you load in a scene, everything you load gets stored in your system memory. When you go to render it, whatever is visible (or marked visible, whether you can actually see it or not) is loaded into your video card's memory to be rendered and for the shaders (which are programs run on your video card itself) can access them. So when you click that EYE icon to hide something, it will not be loaded into video card memory. Even part of a character's arm as I stated makes a difference. You could free up video memory and increase the detail on what is visible and maybe it wouldn't be too bad.... dunno... certainly it speeds up renders. For example, here's a scene I rendered on my older 1050TI...I'll try to look into some HD skins. The last time I raised the subd level, my PC lagged pretty badly, so I tried to keep it lower. The skin detail might have also suffered due to the lighting. Thanks for the advice!
This is a good advice, you can also go much further.Yeah, you do have to be careful with what your PC can handle. What I used to do when I had an older video card is I would hide EVERYTHING that was not visible...
I used to reduce texture size using scene optimiser which worked well. I never had to delete anything. I only had 4G of VRAM but was able to do quite a bit just by hiding. The bonus is that once I got a better card I could reload the scenes and unhide things... which I actually ended doing.This is a good advice, you can also go much further.
-Turning down texture max size in render settings
-Rendering at a lower resolution.
-Lower model subdivision level. (this will help a lot but can affect close-up quality).
-Using the spot render tool to render the image in parts.
Hiding items in a scene does reduce vram usage, but for some reason hidden items still use a little bit of vram during a render so deleting them fully is the only way to get 100% of the vram back.
cpu rendering is also viable if you have a half decent cpu, it just takes 10 times as long.
Also also using aYou must be registered to see the linksis essential for low-iteration images.
It's impressive what you managed to do with just 4gbs of vram. How come you didn't resort to cpu rendering though, just too time costly?I used to reduce texture size using scene optimiser which worked well. I never had to delete anything.

I have an interesting render from the dark days of low VRAM... the following render was one I started by accident as I didn't have the camera selected, but I let it go anyhow as it looked interesting... almost some sort of strange art. heheheh... but it showed just how much I hid from view (I had also reduced texture size for these)...
First, the accidental render...

This may look confusing until you see what the real scene was SUPPOSED to be...

If it wasn't visible, I hid it. I actually created a script so I could just click on something and press "V" to hide it rather than clicking the eye icon which really helped.
This is one of my old renders I did after reducing texture size and just hiding everything...

And this is the same scene after I reloaded it on my new video card and unhid everything and reset the texture sizes back... you can mainly notice the texture difference on the ground outside the door, otherwise it's not that bad...

Yup. CPU rendering would take literally hours. I done all those renders using denoising, usually with around only 100-200 iterations in about 5-10 mins.It's impressive what you managed to do with just 4gbs of vram. How come you didn't resort to cpu rendering though, just too time costly?
I don't do postwork but looks good! When I want to emulate something, I will generally search online for real life images of what I want and then see what I can do to duplicate it. I mostly like to see what I can do with just rendering. Nice work.WARNING: Wall of text in the spoiler.
