Gimp iRacing Spec Map Tutorial - 2024 Edition

This is part two of a two-part series ( • iRacing Gimp Tutorial ... ) taking you from novice to semi-expert at creating paint schemes, liveries, for use on the iRacing platform.
In this video I'll be detailing my workflow for the spec maps feature iRacing added back in 2019. If you have any questions or suggestions do let me know down in the comments below. Enjoy your day!

despite having experience designing liveries for a while now, trying to navigate GIMP after moving away from Photoshop is definitely really humbling - appreciate you creating these tutorials!

I just want to say this might be the most helpful video I've seen on CZcams. You managed to cover practically any possibility a person might need to know and gave multiple examples on the outcomes. I hope other people needing help with specmaps get lucky and click on this video like I did.

Great job on this, you were the only resource I found that concisely showed what the spec map is, how to save it, and how quickly you can use the RGB values as an interface for changing material properties.

[@liambrotherton]

Glad it helped! Yeah I found all the other sources rather unhelpful myself. Let me know if you have any questions

[@STSSRacing]

Big problem for me, when I do the spec-map it makes the whole car black

[@hi_im_sota]

NOOOOO THE METAL FLAKE SECTION IS SO SHORT 😭 I need more information 😭😭😭

[@user-oo4lx9kx4x]

mine looks good in iracing paint shop untill i load into a track then it turns all black weird

[@liambrotherton]

Hmmm could be that you have the trading paints installer running and its overlaying a different spec map onto the car than what you want. Make sure you are in paint mode or just kill it in task manager as you are painting. Hope this helps!

With all due respect, you covered WAY TOO MUCH info in this video. And honestly I still don't understand how spec layers work.

[@RowdyGromwwwww]

Gimp really pisses me off i do the bullshit you said and all it does is turn my car red..., and photopea what i normally use, well i have no idea how to just simply add fucking metallic... I don't understand why they make this bullshit so fucking complicated.

[@liambrotherton]

Hey, based on what you mentioned what might be happening is that you aren't exporting the spec file as (car_spec_userid) and rather just exporting it as (car_num_userid) and thus it's replacing the design and not instructing the sim to make the car metallic. Hope this helps!

@@liambrotherton OMFG I had the same problem, been doing my head in and it was like you said, using the proper file name! TY
