Rendering is Very Grainy

I have a very simple issue/question – I have rendered for the first time a few minutes ago but it’s very grainy… Might be difficult but any pieces of advice to improve the quality would be super helpful!

Please find attached my rendering and below my systemdata

First Tip. Make sure the center of the model is placed close to worlds origin (0,0,0)

Second Tip. Enable “Denoiser” you can install it from the package manager. I’d suggest if you can try “Intel Denoiser” .

Third Tip: increase the number of passes unfortunately this will increase your render time but it will provide you with cleaner results.

Thanks so much @tay.othman for your quick help!

I’d like to execute your first tip but I have an issue. I have multiple saved viewports and I think if I move the model, all my saved viewports will become useless. Is there a way to go around this?

Do you mean “Named Views”? Give this a try.
On the named views panel right click on each named view and click on show widgets.

Otherwise I’d skip Tip 1 and continue to Tip 2 and Tip 3

I’ve already tried 2 and 3 and it improved it a bit - thanks a lot!

I still want to try 1 if possible. This is what I get from the settings panel, is there a trick to move these views together with the model?

I was referring to “Show Named View Widget”

@tay.othman Thank you so much that worked perfectly :relaxed:
