Hello,
I've been messing around with an issue I've had in-game for a few months now, but unfortunately have not been able to fix or even fully understand.
It is regarding the way road surfaces are rendered and reflected onto cars. Here are a few issues I have encountered, I hope that these can be fixed and I am just running a wrong setting.
-Road surface below the car being reflected inside the cockpit, coloured kerbs are reflected onto the car's glas/carbon or metal materials inside the interiour of the car.
-Road surface is reflected onto the car's body but is a little too reflective/noticeable. Again this is very noticeable with kerbs, sometimes being reflected like a mirror onto the car's carbon parts.
What frustrates me the most is that the issue will be more noticeable on some cars than others, the reflective values of the car's materials could be an explanation. The issue is however as far as I know, is present on every car but exactly how present it is varies a lot, it could just be slightly noticeable on the windshield wiper, or very noticeable on the car's carbon dashboard, or the entire carbon diffuser.
Below are some videos to illustrate the issue with reflections as best as I can.
Cheers and thanks for the help ^^

yes that is a major pain , esp in VR it can be quite immersion breaking.
You can alter the reflective properties of any material, with extension code , play around with it :
[SHADER_REPLACEMENT_...] ;improve carbon
ACTIVE = 1
MATERIALS = name_of_material_here
PROP_... = ksAmbient, 0.13
PROP_... = ksDiffuse, 0.08
PROP_... = ksSpecular, 0.5
PROP_... = ksSpecularEXP, 180
PROP_... = fresnelMaxLevel, 0.05 ;esp this one , lower is less reflection
PROP_... = fresnelEXP, 40
PROP_... = fresnelC, 0.01 ;esp this one , lower is less reflection
PROP_... = useDetail, 100
PROP_... = detailUVMultiplier, 14
PROP_... = detailNormalBlend, 1
DOUBLE_FACE_SHADOW_BIASED = 1
BUT if the material is chrome , it SHOULD reflect... but it should be made impossible to see the curb reflection from inside the car as it should be consealed by the car chassis and doorpanels ...
So anyone has a neat trick to force that via extension? (I guess that is a fault of the creator , and needs to be dealt w in 3D program, and can't be fixed w simple extension code?)
Is that particular texture tiled?Changing its dimensions would change its tiling needs. Or maybe the texture needed its alpha channel and it was lost during the conversion.
no , when I resized it w Gimp it was all good ...
the resulting dds looked very weird after having it being converted by XnConvert ...
also attached the resulting DDS (remove .txt) , maybe someone can figure out what happened?
The original dds looked like :
(and can be found in the
original post if you wanna download it)
It would be good to know the case in which NOT to rely on XnConvert (esp when doing batch resizing , it could be dangerous to loose stuff - if you don't backup first that is)
