Trigger Words:
Main trigger: r4ym4n
Helper prompts: parody, style parody, toon
The LoRA can potentially work with no triggers, but it may not be strong/consistent.
For a stronger effect, use the main trigger: r4ym4n. You can also weight it numerically or with parentheses - I usually do (((r4ym4n))).
If the (weighted) main trigger is still not enough by itself, next try the helper prompts, individually or in combination, along with the main trigger. They can be weighted as well - I usually do them all together, like (((r4ym4n, parody, style parody, toon))).
The "toon" trigger is not totally necessary to get the style, but I find that it usually helps push the LoRA to an even more cartoony style that fits the aesthetic well. But please note that the effect of the "toon" prompt is coming mostly from your base model, not the LoRA, so it may not always be consistent, and it may not always fit well. It's always good to try with and without first to see what it's doing.
Please note that the main trigger here is only for the Illustrious model - it won't work for the SD1.5 model. The helper prompts may or may not work for SD1.5 (I never tried them), but they are not necessary as the SD1.5 LoRA works just fine with no triggers!
At a Glance (Illustrious):
Base model: Illustrated style (I usually use my own Illustrious merge or WAI)
LoRA weight: 1 (but slowly go lower or higher if necessary)
Suggested parameters: Euler a, Automatic, 30 steps, 832x1216/1216x832, CFG 5 (but feel free to experiment!)
Hires. fix: 1.5x, 30 steps, use a quality upscaler (like 4x-UltraSharpV2), denoising strength 0.5 - 0.3
Extra: use ADetailer to fix faces and/or hands if necessary
Illustrious Version Description:
This LoRA will give your images an art style resembling the modern Rayman games (Origins and Legends, but mostly Legends). It works very well for the general aesthetic, but not very well for detail. I'll go over that and some other issues below.
First, as I mentioned above, while the general aesthetic is good, the LoRA appears quite smudgy when you examine fine details closely. Like, if you zoom in or check some fine details closely, they can appear kind of muddy or garbled. This is especially true with stuff like fingers, accessories, fine details in the background, etc. I don't consider this a dealbreaker though, as the game's art style is cartoony and exaggerated anyway, and if you just view the images at normal size, most of the time its flaws are not super noticeable.
Second, I mentioned this above in the Trigger Words section, but it's worth reiterating: the "toon" trigger can have a very strong effect, but is not always necessary in your prompt depending on your base model. I find that it usually helps when I use my standard base model - not only in aesthetic, but also with colors, details, and anatomy. However, all of those effects are mostly coming from my base model and how it understands the "toon" prompt. Other base models may have a different understanding of the term, and it could possibly clash with the LoRA's style in some instances. And if you use a base model that's already in a more Western cartoon style, the trigger is probably very redundant and unnecessary.
Finally, it has some trouble keeping track of objects that move behind other objects, if that makes any sense. Like if there is a bed behind the main character, the bed might not line up properly on each side of the character. This seems to be a general Illustrious issue in my experience, but it's seemingly a bit worse with this LoRA. So you may need to do some post-processing, or just hope for good seed RNG.
For more potentially relevant information, you can check out the original SD1.5 description immediately below. Below that, there's a troubleshooting section in case you're having any problems.
SD1.5 Version Description:
This LoRA will give your art an influence from the modern Rayman games (Legends and Origins, but mostly Legends). So basically it will add an exaggerated cartoony/illustrated effect.
In general, this LoRA seems to work pretty well. Its main weakness is that it's not great at working with concepts that are pretty far removed from what was in the training image set. You can see this with my indoors showcase images. It will add the Rayman effect to the stuff outside the windows, but a lot less to the stuff inside. There were some indoors images in the training set, but I think it was mostly stuff like castles, so you might have better luck with stuff like that rather than contemporary settings. Just play around with it!
Here are some other basic usage tips for the LoRA:
1. It works best with cartoon/anime models, but some 2.5D models work well too (especially if they skew a bit towards the illustrated side). You may get some effect with realistic models as well, but I can't promise great results with that. No harm in experimenting!
2. I mainly use it at a weight of 1, but sometimes you'll get small or no characters at that weight. It doesn't seem to happen frequently, but it does happen here and there. You can always lower the weight of the LoRA in 0.1 increments until you start getting what you want.
3. Use a VAE, especially if your chosen base model doesn't have one baked in! It really seems to help with getting better colors and anatomy.
4. Upscale or use Hires. fix with a quality upscaler. If Hires. fix seems to be destroying your images, try lowering the denoising strength.
Troubleshooting:
If you're having persistent problems with anatomy, fine detail, and/or other jank, just try your best with all the usual fixes - different prompting (including negative prompt), try a different base model, use a different VAE, try different clip skip values, adjust the LoRA weight, use adetailer, inpaint, etc.
