Too much noise after rendering

I was getting messages saying you are using an older version of V-Ray - you might want to try installing v-ray 6.

I am actually using Vray 6

That’s strange.
The first thing I get when I open that is that there are old things that need updating - I wonder what that refers to.

So, I’ve defaulted the settings and changed the exposure back - even after just 4 passes with the de-noiser (intel open image), it looks ok

It feels like this is taking longer to render than it should, there must be something that is causing that.

And I’m also using Skp 2023

this is the latest that I got. (I have modified some structures). There’s still plenty of noise even I’ve already set the Denoiser to ‘strong’.

Also, I’ve updated my V-ray. And now I got the same message that you had.

I’m trying to render it again and see if it has something to do with the update.

Can you share that current one?

I’m still rendering it tho

they’re both on 6… I didn’t know that there’s already 7.

I’m sorry, my bad memory. I’m on 5 and 6 is the new one.

No worries. I’m using V-ray 6, the file is created using it and my skp is 2023. So I’m not sure if this could be the issue.

So having a look closer - the material that you have on the window frames “black car paint simple” a metallic that is also quite another complex one , I think much of the noise you are seeing are from the flecks in that metallic material not quite making it.
There are a few other materials that look like they have been made in unconventional ways, I’ve swapped them out for chaos cosmos ones. I’ve also replaced a bunch of materials that are missing specular or reflective properties or have errors (the wood table top was set as metallic) - those will stop light behaving correctly.

Try this one - hit render and make the denoiser visible.

stop it when it looks good enough rather than letting it run and run.

This took about 3 minutes before I stopped it - I’ve set the opacity of the denoiser to 0.8 as I think you always want a little grain to stop it looking quite so clean

thank you so much for this and sorry for the late reply (different time zones). I’m on the rendering process now. Do you know where to get a material library with proper setup cause I’ve just downloaded it somewhere else?

And how did you make the color of the materials looking as they really are (ex. ‘Ivory vinyl’ for the cabinet used to be checkered pink and you turned it into ‘white’ in skp, another one is the ‘carpaint black simple’ I believe it used to be checkered light purple and you turned it into ‘black’?


And it’s working now! It’s pretty far from the result I got yesterday.

You’re welcome. It was a Friday challenge for me, always trying to learn more and get better. The chaos cosmos assets are going to being a good place to start - use the window glass, glass , wood and various other materials there. They are mostly setup using the generic material setup.

For everything else , even starting with even a SketchUp material as a base - you can just set the reflection colour to around 50% along and adjust the glossiness/roughness scale until
The material looks like an appropriate level of Sheen.
Metalness should only ever be 0 (not metal) or 100% (metal)

If you take a look at the specular (the reflection colour) and the reflection channels in the render buffer , you can easily spot the materials that have not had these set, they will show as black - all materials should have them.

There is a setting on the material for “binding” which changes how it displays.

If the material isn’t using a standard photo texture of a plain colour then it will generally show as a checkerboard pattern - there are normally the procedural textures or are more complex materials

Thank you! This has been really helpful.
