Gimp iRacing Spec Map Tutorial - 2024 Edition

[@phlmnn]

I just want to say this might be the most helpful video I've seen on KZbin. 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.

[@MD-bi1re]

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

[@CaptainParallax]

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!

[@KlausOberländer]

Super video and everything explained very well. I'm following all the steps but can't get the stickers to be matte. Despite locking the alpha channel, the whole car is matte, and the white stickers are gray.

[@KJACRACING]

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

[@RelkinGame]

Can it be done with the tga I upload to trading paints???

[@Bruchaa]

Spec map not showing up in 3d view and MIP file is not being created I have no Idea what I am doing wrong

[@fullsendmotorsports77]

Did you save the spec map as car_spec_number.tga?

[@pikagumba3083]

Could this be done on a Trading Paints livery automatically for all those who race it?

[@matthewwarholic]

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!

[@StudioDaVeed]

My God did all you guys that give tutorials have a meeting where you decided to talk as fast as you can and move your mouse as fast as you can?

[@hi_im_sota]

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

[@donwebb5698]

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

[@drybonesmalone6974]

yep, should use a simple car design without so many layers- i have idea what the f he has done and ive been doing liveries for years now

[@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!

[@logieuk]

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