How to sharpen textures?

[bratro]

I'm having a hard time to make my textures sharp and crisp with the octane renderer. I have a lot of booth elements where there are some kind of posters/visuals included and there is most of the time some text in it. as you can see in the examples below, the text/logo always looks kind of blurry. for comparison I also made a render with the cinema standard render. Now my question, does anybody has some tips or tricks how to make these elements more sharp with the octane render or with which settings do I have to play around? (the octane scene has a simple sky element and the camera is set to Fstop = inf / Aperture = 0)

Any help is very much appreciated

Hi bratro,
have you tried with the "Filter size" set at 1 in the kernel settings?
