All objects besides the background are made with 3D objects but somehow the font has bad quality
When you select the text and then in the 3D & Materials pnel in the top right corner click the button, you can set the Raytracing options. Try higher settings.
I rendered it on the high settings and it looks like that.
And everything else also has 3D effects applied? Or are the other items already pixels?
Can you please check Effects Document raster effects settings? What is the resolution?
How far are you zoomed in?
How is your color management set up?
If that does not work, please upload the file to Creative Cloud or the like and share the link
Thank you, I changed the resolution in the raster effect setting and now its much sharper. I'm new in the Ai so i dont know much about the setting etc.
Glad you could solve it.
