Also I have 32 gigs of RAM but I guess it don't use any in GPU rendering.

>why does it balloon in the scene?
Because its compressed but for raytracing you need honest 4k*4k*3-4 bytes. Per each bitmap.

Blender is a piece of shit in this regard because all the baseddevs have 64 niggabytes of vram on their rtx 6969 cards and will never bother to fix it.
You have to make LOD models anon.

Good to know it's not just me. Guess I'll sell my liver and buy 24 gigs GPU.

I recommend having a look into what Dazlets do when rendering. They might not know much when it comes to 3D but they do know their rendering. None of the stuff Daz puts out is optimised in any shape or form as well.

Personally I'm an NPR guy so I don't really bother with renders but I had no idea that you could just get 10 4gb graphics cards and have all their video memory pool together in Daz. The Nvidia Quadro costs something like 5000-10000$ for 30gb vram. Or you could do some crazy shit and link a bunch of older cards and get the same vram for a fraction of the cost.

Or just pay for a renderfarm.

Welcome to reality. Cycles is an unoptimized messy renderer. Another reason to stay clear off free software.

There is not much you can really do besides aggressively cutting down everything that is not in front of cam. I usually downscale all textures save for skin albedo/normal maps by at least 2. Daz also has plugins to automatically hide all objects that are not in viewport. Another thing I've been recently considering, is to use really low textures for everything except for face, downscale render to 33-50% and then reupscale to 1080p with topaz and then photoshop face in.

prolly the textures
limit them to 4k then 2k in the render settings
other than that may be to much geometry so temper with the subdivisions

I've got 8 gigs of VRAM (GTX 1080), and 16 gigs of RAM and never ran into this issue, save one or two times when I was using 8k maps for some retarded reason. Or I was using Eevee and trying to render something at higher than 10,000 pixels on one side (people talk about Cycles being unoptimized).
What does your scene look like in terms of vert count and texture sizes? Seems like you're trying to ask way too much of your system than you realistically need.

Just some coom stuff with smutbase models. Sometimes with content ported from DAZ. I can't do shit in DAZ though.

I render exclusively in Cycles and I don't think it cares about resolution or sample rate. I can bump it to infinity and as long as it loads in the beginning it will render.

Is it just the textures? Does excessive subdivs increase VRAM use? Particle hair?

u can just use render farm or render limited frames.

Normally 70% of scene's weight during rendering is textures for me.
>Does excessive subdivs increase VRAM use?
As I understand it, when you have displacement map the model gets subdivided so basically every pixel of disp map gets polygon of its own. That amount of subdivision can double or triple scene size easily. But I don't think geometry has to be in GPU RAM.
>Particle hair?
Yes, but once again, it's just geometry.
