The effect itself is likely produced by a shader, which in turn is likely used in many other places. I would think, you’d have to figure out where the trigger is for those ‘objects’ you wish to disable it on. A good place to start searching would be the various ‘globals’ in the root folder.
On a side note, is this an effect that is VR specific? I don’t see any change when getting close. In case of creatures I only see the interaction popping up.
I found the following in GCGAMEPLAYGLOBALS:
PassiveScanEffect
<Property name="PassiveScanEffect" value="GcScanEffectData.xml">
<Property name="Id" value="" />
<Property name="ScanEffectType" value="Creature" />
<Property name="Colour" value="Colour.xml">
<Property name="R" value="1" />
<Property name="G" value="1" />
<Property name="B" value="1" />
<Property name="A" value="0.7" />
</Property>
<Property name="BasecolourIntensity" value="0.1" />
<Property name="ScanlinesSeparation" value="0.5" />
<Property name="FresnelIntensity" value="3" />
<Property name="GlowIntensity" value="0" />
<Property name="WaveOffset" value="0" />
<Property name="WaveActive" value="True" />
<Property name="FixedUpAxis" value="False" />
<Property name="Transparent" value="False" />
<Property name="ModelFade" value="False" />
<Property name="FadeInTime" value="0.5" />
<Property name="FadeOutTime" value="0.5" />
</Property>
I found it a possible candidate for creatures at least, but could see no difference myself, as I do not have VR. I had changed the alpha value (A) to 0 for the colour assigned.
There may be possible other candidates you could try, especially the ‘globals’. Would be a starting point for me anyways. Maybe there is a range/distance defined somewhere for triggering the ‘focus’.
You could always seek help on the main NMS Discord (modding room) or the NMS Modding Discord.
