My render is too blurry

[soomin_lee]

Hello,

I'm starting to play with Vantage.
So far, I've been using Rhino + V-ray, and from that workflow I could make out this much quality.



However, I imported vrscene with the same set value from Vray and the render keeps blurring out so much.
And I am taking so much time trying to figure out what the problem is.

Looking at it closely, it's works like a low-resolution image eventhough it's actually 1920*1080(FHD).



I really like the workflow with Chaos Vantage and would like to apply it to my future career.
Can you suggest any solutions?

There seems to be some issue with the images - we can't see them.

sorry, didn't realize

Thanks, I can see the renders now. Those are completely different images, day and night. But I see what you mean about the low detail. Is this a final image generated from the Vantage render dialog or is it a capture of the viewport? The viewport supports upscaling, it is indicated in the status bar when enabled. (Upscaling means the render result is AI-upscaled. You could also stretch the viewport to fit the window size, this is a separate function toggled by a button next to the resolution settings on the left)

It looks like you have lots of light sources. Try enabling "reservoir resampling" from the render settings panel on the left. It works well for large numbers of lights.

More info could be useful, like screenshots of your render settings panel in Advanced mode. Also which version of Vantage are you using, what GPU, which denoiser...

First, the image is the final rendered image (for test), and not the screenshot.
and these are the settings of the render. (by the way, I couldn't find the AI-upscale box)







It's the latest version of Chaos Vantage, and I use NVidia's RTX 4060.
I've rendered it with both the Nvidia AI and the Vray Denoiser and two of them had the same blurry result.



yeah that's for all.

-> with vray

In your screenshots upscaling is enabled for the interactive viewport - it's the "DLSS Performance" setting in the top toolbar. If you set it to 1X it will render at full resolution (slower, but cleaner). DLSS is only available in interactive mode. The offline Optix denoiser does not upscale.

I suspect the main reason the image doesn't clean up is the Noise Threshold setting. Similar to V-Ray, this tells the renderer when to stop sampling a pixel. 0.1 is a very high value so it would stop sampling almost immediately. Try using the default value of 0.01 or less. If you set it to 0 every pixel will be sampled indefinitely until a fixed sample count limit is reached, such as the sample count you specify for offline rendering.

I forgot to add, if your denoiser for the viewport is only DLSS, it may have a hard time cleaning up some lighting details because it does not accumulate samples when the image is static. For this to happen you need to set a different secondary or primary denoiser from Edit->Preferences->Render Defaults. This setting is for the interactive viewport only. The default is DLSS + Optix so you're probably using that already. If the DLSS slider is set to 4X, when the denoiser switches to Optix (you will probably notice the change in the viewport), it will use the upscaling version of the Optix denoiser as well, and vice-versa if DLSS is at 1X, Optix will work with full resolution input as well. The important thing is that in offline mode we never upscale.

I know it may sound a bit confusing, but there are multiple denoisers and modes that became available over the years, each with their pros and cons, so we have many possible combinations.

problem solved!!!
thank you so much for you time. the result was great

before)



after)



v-ray)



result - same quality as v-ray

problem solved!
