Any tips for better images?
Hi SundayPunch,
I've been fiddling with your model off and on for a couple of months and just can't seem to get cohesive images. Aircraft are asymmetrical, trucks or equipment look like they're stacked and melted together, and anything in space generally suffers from skewed perspective to the point that they just look funky.
I've been unable to generate anything even close to the quality of your sample images, so I was curious if there's any special term or style I should use for better images. I'd appreciate any pointers because I like the 'hard sci-fi' look your samples have and would like to accomplish something similar.
Thanks!
Hey, sounds like you are having the sort of problems that can come from trying image sizes too far off from the native 512*512px resolution the model was trained on. Try generating images with at least one dimension close to 512 and see if that helps. You can try upscaling afterwards. Also, SD in general doesn't have a very good idea what a spaceship or aircraft looks like. It's better with some vehicles like cars/trucks, and better still with most kinds of structure. I have found symmetry is a problem for SD, it doesn't really understand it very well. I think we don't notice as much with buildings, landscapes etc since it's not so important, however an asymmetric aircraft just looks immediately silly. You might also have better results using this model in img2img mode from a source image.
The sample images were generated with pretty simple prompts, here are a couple of examples below.
combotechsf, dilapidated desert truss structure
Steps: 100, Sampler: DPM++ 2S a, CFG scale: 10, Seed: 1049527356, Size: 960x512, Model hash: 2f5159bf, Wildcard prompt: "combotechsf, adjective style scifi"
combotechsf, serious simple industrial vehicle
Steps: 100, Sampler: DPM++ 2S a, CFG scale: 10, Seed: 1049527339, Size: 960x512, Model hash: 2f5159bf, Wildcard prompt: "combotechsf, adjective style scifi"
Hope this helps!
Thanks for your reply!
I generally run 512x768 or 768x512 with Hires. fix set for the same dimensions for clarity and sharpness. I've tried low steps with DPM++ sampling methods and 100+ steps with Euler A and DDIM, all with wildly varying rates of success. I'd estimate that 1 in 75 is without merged, morphed, or stacking issues.
I'm in agreement with you about the symmetry issue. Fore and aft facing cockpits on a fighter does look pretty silly, especially when the thrust nozzles are next to both.
Was that your MEGASTRUCTURE post on Reddit? I found it last night and played around with some of your prompts, but didn't see any noticeable differences to what I've already been generating.
I'll give the wildcard recommendation a shot. I've not yet played with those settings, so time to learn something new.
Thanks for the model, by the way. When it hits for me, it hits homers. I'm just trying to up my average.
