How to get consistent perspective lines? (lemmy.world)

Is there any tip to getting more consistent continuing lines when there's some subject or object in front of it? Like for example when theres a fence behind the subject and the height of the fence is completely different on either side of the subject. This happens all the time with windows, railings, seats, and any sort of straight line in the background.

I've thought if one solution is to pre-generate the background partially before adding a subject or something like that.

Controlnet of some sort is your best bet. You'll probably need to render an imperfect scene, spit it out as a lineart png, take to photoshop and draw the lines in more correctly, stick it back into controlnet (without pre-processor) and re-gen with the same seed and prompt.

You can do multiple rounds to get it just so.

You can just doodle a guide image for SD, but I am not good at it so I spin through until I find something I can fix.
