Generative AI to make tire skids decals?

Those sort of dark stripes from blocked wheels  racing cars do in turns.   Could somebody  suggest one and what the hell should be the  promt wording .    Whatever I try   come with something pathetic  looking .    Photoshop  can generate something  quite nicely looking  in regular perspective camera , still unusable due to low res  but when I try to nudge it to top camera ortho style image  it does an utter crap.     Midjourney  and anything else I tried do  something cartoon style fancy  looking  or wilde .   Chat GPT draws me pictures of something repetitive  and  so weird looking  always on sort of concrete blocks for some uncertain reason  having not even a hint it might be of a real world. 
 Where is all that AI generative power when you need it ?    

Those damn decals always looks like someone  draw them  with one dub brush  in photoshop by a low dpi  mouse.   So I hoped that's the areas where AI would shine.

    That's exactly my experience - neural networks are great when you don't care about results, but if you want something specific and for it to have high enough quality for production it's just pure disappointment.

    Try to generate closest thing you can with photoshop and then try to improve the quality/resolution by upscaling and inpainting with MJ or SD.

    Well , Photoshop at least trying .     Here is what Stable Diffusion does:

    Is my wording bad  or something?   looks like only things  AI is comprehending  are tire and  racing track .    
     I started to do SDesigner generator with its curve nodes    but it turns to be a hell of an  artificial look  . reseeding  them  to death.   Feel I am falling  into bottomless hole and  will waste forever  on this.   So need a simple quick  way to do naturally looking variations .

    To clarify - I meant inpainting, not generating from scratch. As in get generation from photoshop (kind of what you want, but poor quality) and then run THAT through other NN of your choice or maybe PS again. Idea is for NN to remake existing guiding image with higher details, quality, resolution.
    With SD you can use comfyUI to get more control over the process. There are installers that take care of most tedious convoluted parts and dump ~60Gb of stuff on your PC. You would still need to figure out how to work with its node system. Or if your are lucky maybe someone already made one.

    Imho SD generates not as pretty as MJ, but can run locally so NDA-friendly if you care about that. You can use controlNets that allow you to guide images by depth masks, contours, style example image etc
    MJ is much easier to use and does a better job, but usually not what you want.

    Designer graph will probably give you best result if you are willing to put a lot of time into it. But you will have full control over every step and you only need to make it once to get guaranteed coherent results feeding it different splines as input.

    It's not great. I think if you wrote that prompt to a human artist, they'd have questions and need clarification. The human perspective is what I'm coming from here, so, there's no guarantee a humanly better worded prompt will get you what you need, either.

    I'd personally use "top down" instead of ortho (which is short for orthographic anyway), and isn't really a common term outside of 3D.

    Maybe something like "Top down view of tire skid-marks"  or, if the turning aspect is important, "Top down view of tire turning skid-marks", and tack on other important words I may have left out (racetrack, nascar, whatever)

    Well, it does sound like a good case for a couple custom brushes. Brush size / resolution might be a problem, so upscaling would be the application for AI, here. Maybe use ZBrush or a different software with more controls for how the strokes are laid down.

    Other than that, make sure to add terms for what you are actually expecting to see and in which context this would have been part of the training data,  e.g. texture, decal, brush pack

    Perhaps instead of skid marks, you could ask the plagiarism machine to generate some pictures of shit stains ?

    And as an added bonus, no further prompt engineering will be needed to get some clean alphas on a white background.
