How to get more sharpness?

[dinf]

Hey folks,

don't know if this question already came up, didn't found something comparable through the search.
I'm setting up some natural scenes with photogrammerty objects from megascans. But when I render them, they are always a bit blurry and never as sharp as the preview pictures of the seller. I could render all in 200% and scale it down back. In this case I get near, see attachment.
The left is the vendor's preview, middle 100% rendering of Octane and right 200% rendering, scaled down with lancos. The scene is simply the geometry plus a octane sun and the imager set to linear + 2.2. gamma to get near to their colors. I won't upload this thingy due to copyrights, but the material is marked as "free" from the vendor if needed. The scene itself is not, so material, light and camera will differ.

But probably there are ideas without looking into the scene.
So here's the question: what I'm doing wrong, if any?
Are there probably options in Octane to get more sharpness?

Thanks alot!


Well ... is this maybe due to the new adaptive sampling? Simply activating it does not change much, if any.

Hi dinf,
did you already set the Filter size at 1 in the kernel settings and the Aperture edge at 0 in the Thinlens camera node to remove the DOF completely?

Hey beppe,

thanks for fast answering. No I didn't set the filter size to 1, but I'll immediately give it a try.
I also didn't set the Aperture edge to 0 because I used Cinemas default camera. Maybe Octane is using the defaults then?

However, using a camera with Octane Tag didn't let me change the Aperture Edge to 0, it switches back to 1.

The rendering with other filter sizes seems to change nothing, even with 0.001. I always get a result near to my first, more blurry rendering.Tried also different combinations of focus, aperture, f-stops and so on, without getting any crisper response. Btw: I never asked myself, how AA is working in Octane, it was "simply there" ^^ So how is it working? SImply with "filter size"?
Thanks!

FYI: this is rendered with a 4K set of textures. But the 8K set does not show up crispier also.

dinf, I briefly played around w/rendering photogrammetry in octane the other day and had the same experience. I didn't play around with the settings but I did come away a bit disappointed with blurriness in results. Don't know why.

Thanks for letting me know! Probably Ahmet or some of the core team will come around and say something about that point also.
I'd appreciate that
