Deejayyaj: You could tone down the reflectivity for FBM paint, now it looks alot like chrome. There's also some noise in tire tread and sidepods that could probably be fixed by adjusting rendering settings.
As for XFG, you're missing textures/materials from thin strips on both sides of windscreen, mask badge, metal hooks wich lock bonnet and trunk, centerpoint tape on steering wheel and outer edge of alloy wheels.
Cheap plastic gray doesn't really fit well on mirrors, try black or deep purple similiar to body color.
In FBM: Im using the Output material for tires and sidewalls, So I have to adjust the tone for tire tread and side wall.. ok ill tweak it. About the body, i set the 1st default to Chrome and the 2nd default is the skin... so i have to tone tweak the 1st default as chrome to tone down the chromatic effect.
In XFG: Yeah thanks for reminding me about the windscreen, mask badge, metal hooks, centerpoint tape on steering wheel and outer edge of alloy wheels and also the color of the side mirror.
Actually the Mask Badge is blank, in the Skin i left that as blanks for future badge
and the outer edge of allow wheel is set to chrome, so maybe i'll just tone down the chrome effect for this. But sometimes it has a good effect in different angle due to white box reflection and sometimes too bright.
Ok so I have to map the missing materials as said above.
The windscreen, metal hooks, centerpoint tape steering wheel and change the color of the side mirrors.
Thanks "Crommi" for tips.
This helps me.
Edit: I forgot to ask you Crommi, Im wondering what is this white thing coming out of both sides of windscreen?
Most likely it's template for texture you'll see on edges of the windscreen, those small black dots that smoothen the transistion from transparent to black.
