Any tip on optimizing the imported daz figures to lower vram usage and make rendering time faster?

[VP]

First of all thanks Thomas again for this great plugin!

When rendering the daz figures, especially when having multiple figures on the scene with clothing (i’m just rendering the figures so there’s no props or background), I often get VRAM using a lot (like 10GB), often it will max out on my computer and run into the optix error invalid value

Also the rendering time is around 2 mins per image using cycles. I’m trying to see whether I can find ways to make it faster (as I need to render short videos).

my setup is Ryzen 7 5800X + RTX3080 10GB + 32GB DDR4 3600MHz RAM~

Wondering whether anyone can share any tip or advice on how to optimize the daz figures?

Much appreciated Thanks!

You can reduce VRAM usage by simplifying your scene during rendering in the renderproperties tab;

This is a very good article about optimizing rendering; https://www.cgdirector.com/how-to-render-faster/

The plugin also provides a tool to Resize Textures destructively. In addition to speeding up rendering, this also speeds up loading the textures compared to the built-in simplification, which I think loads the full textures and resizes them dynamically. Note that you don’t have to install OpenCV to resize textures anymore, the docs are outdated in this respect.

Also avoid HD figures whenever possible. Then if you’re rendering animations you may prefer eevee over cycles, and use principled instead of bsdf. See #377.
