Windshield reflection intensity not working

[FlyingRaccoon]

Hello everyone,

There are multiple issues being discussed here:

1. Cubemap reflections: they are based on the mix of the cockpit cubemap defined with cockpit.cfg cockpit_type parameter and the external environment.
   These reflections are impacted by the COMP texture R channel. I wasn’t yet able to clarify whether this is supposed to behave like a scalar or if this is binary, as reported by @ZachB
   I’ll do further tests.
   @Jonx I think these are the ones you are seeing in your video. I checked and your windshield material COMP texture R channel is set to 1. Set it to 0 and these reflections should disappear.

2. Screen space / ray marched reflections: reflective surfaces will reflect objects that are visible in the framebuffer. These are the ones causing the instrument reflections. One simple way to confirm this is to move the reflected object outside of the frustum and its reflection will also disappear.
   
   These are not affected by the COMP texture R channel.
   That can still be disabled user side by lowering the “Raymarched reflections” graphic setting to medium.
   Discussions on how this can be resolved are ongoing.

Regards,
Sylvain

Speaking of reflections. The reflections are missing angle checks.
The engine pods are reflecting the inside of the cockpit

Yes — we spent roughly four hours testing every possible approach we could think of.

We tested:

• With and without a comp texture
• Pure material editor values (no comp at all)
• Multiple roughness values
• Different metallic values
• Extensive testing of comp texture color variations, especially targeting the R channel
• Various color intensity adjustments to isolate reflection contribution

The only thing that meaningfully reduces the reflection is increasing roughness, but that immediately causes the outside world to become blurry, which obviously isn’t acceptable for a windshield.

At this point we haven’t found any combination of comp values or material settings that reduces the excessive reflection while preserving clarity.

To be honest, it looks reasonably realistic.
