For me I don't know if it works because before it worked but now I find out the issue and fixed it basically you need "etkc_main" and "etkc" materials to I mean sadly Dev’s for etkc they used the Legacy material from the first version when they released etkc but they added a new one into the main to make it pbr that’s why it’s a strange material --- Post updated --- Let me know if it works now!
Noticed some small stuff: The hood and rear bumper cameras are slightly crooked. Also, the sound kinda goes in and out near the high RPMs.
