Second render too slow after modifying a scene

taiuri

I don't know if someone else has this issue: when I start Daz and render a scene by Iray, it does it in a acceptable time, but if I modify something in the scene and do a second render, it becomes too slow. So I have to save the modification, close Daz, start it again, and render in order to it does it in an acceptable time again.

Do you know how can I solve this issue, guys?

I'm not the best to answer this, so someone with more understanding will tell you better. DAZ is a RAM hugger, when it renders it kind of keeps the usage even after finalizing....Something around those lines. That's why you need to close and reopen the program so it frees up ram.

Make sure you close the first render image window. If it stays open, the graphics card memory it used is not free for the next render.

And there will be a way, or a product, which frees up ram without having to close Daz?

Yes, I close the window for saving the render once it ends to do it, but the issue continues :(

I use https://www.daz3d.com/scene-optimizer

for when my scene is too large it won't fit in my card. However, this does not free up space of your used ram/vram. It compresses certain things in your scene so it doesn't take up so much space. That gives you the opportunity to render more in a single DAZ session.

But even batch rending products like ManFriday's https://www.daz3d.com/render-queue comes with an option to close/open daz after every render it does.
