I'm trying to create a simple animation moving the camera through a curved tube, which has a .png image (just a grid) mapped on it.

My problem is that I see some differences in the lines when I export on Eevee and Cycles. The lines on Cycles seems to be much smoother.

Here you can see what I mean:

Not smooth lines on Evee Eevee

Smooth lines on Cycles Cycles

I've tried using the Smooth modifier but that changes nothing. Both images are rendered using the same sampling values.

Q: Do you know how I can get smother lines for that curve (tunnel) when using Eevee?

    $\begingroup$ Welcome to blender.se. The images seems to be differently mapped, why? Can you show your scene an modifier list? $\endgroup$

Add a Subsurf Modifier, then the curvature will be the same for Eevee and Cycles, but in Cycles less visible because of different texture mapping.

Mapping differs because Eevee doesn't support the Panoramic camera type (set for Cycles). Eevee is using Perspective instead. Should be probably reported as a UI inconsistency.

  • $\begingroup$ If you have a time please post it as a bug. Panoramic set in Cycles appears when switched to Eevee. Title stay Panoramic, but setup is Perspective. My screen it doesn't illustrate (I just switched type in cycles). $\endgroup$
