Thank you so much!
I am still working on it, so I probably gonna release it tomorrow or maybe tonight already. I completely reworked the head unit, modified the window layout, the stripes and some minor improvements.
I will modify the bistro car as well, the window and door layout with the alpha layer and the normalmap.
I also modified the consist so the AVE 103 will have 4 power cars instead of 2, like the real one. If you don't like it with all of the pantographs up, then anyone can change it to normal car. However I don't know where can I modify the power of the vehicle, it is now 11000+ kW instead of the real 8800 kW. The top speed is already modified to 350 km/h.
After that, I will check the NS version and modify it a bit as well.
Then I will check how should I pack the files to make a good mod upload with mod manager compatibility, I am a very beginner so I don't know what to modify to give credits. I will include the original files so it contains the author as well I guess, but I will mention you!
