Are you using Vulkan DXVK or RWEnhancer 2 with Vulkan ticked? The fog shader isn't compatible with Vulkan, I did contact Richard (AP) about it last year and I even put him in contact with the RWEnhancer 2 Dev so that he could share the fix with Richard, as he addressed and fixed this issue with RWE2 using Vulkan, unfortunately the APSWEP undoes this fix because it replaces the corrected shader. I don't know the outcome of that but Richard did tell me that it may be too complex or may even break something within his modified shaders so may not even be possible to implement the fix, my recommendation - disable Vulkan when playing a foggy scenario, also wouldn't hurt dropping AP a support ticket to see if there ever was a fix in the pipeline (but only if you are indeed using Vulkan via RWE2 or DXVK)
Not using any external enhancers because I'm fine with the AP shaders, but as Reef elaborated, this looks like another shader interfering with the AP shaders.
I have once noticed this myself on a route with relatively gray skies in one direction but some trees quite literally glowing. Not all! I suspect it's some antialiasing / transparency hiccup. Either the skies behind are in fact very bright, or certain trees use that value regardless. (A lot of weather includes colored fog, as far as I can tell, resulting in glowing trains and massive shadows in rain, or my often remarked white fog at midnight. Point is, just because the fog is gray, what's behind may be something else.) It may have something to do with outlining, which I didn't notice at the beginning but definitely do since 2021. It is meant to be subtle but as with many things, zooming in shows it in action. Usually it's visible surrounding people at stations but it also emphasizes objects like buffers, chains, everything. And that everything might include trees, and their background.
Andras' post is unrelated to the topic (I think, as there's no screenshots.) In fact, the AP Sky & Weather Enhancement Pack 2.0 has fixed a lot of core issues. Fog at night was a problem because fog used to brighten things up through a white alpha channel mask. Also the distant fog colour is not tied to the upper sky colour anymore, which removes the deep blue mountains effect. Even the default RSC skybox (featuring the big cumulus clouds) was not really compatible to the core weather patterns (2. Cloudy), if you notice the upper cloud layer consisting of these small white clouds was moving at an unrealistic speed, looking awkward. (These still used weather patterns were designed for the original Kuju skydome which rotated three spherical layers in all directions as opposed to the RSC/DTG skydome with the horizontally moving cylindrical cloud bands. Also the new AP shaders make the world appear brighter and a bit crispier. AdaptiveBloom is perfect now, without overexposure and blur. The APSWEP2.0 is the single most valuable update to the game, as many of the default TimeOfDay skies and weather patterns look completely off and ruin the routes. The issue here was applying shaders on top of AP shaders. (Like applying too much Sharpening on an image gives these edge artefacts.)
Yep, what Spikee1975 said.. So in summary. Standard 64bit game no 3rd party shader add ons including AP SWEP = No issues 64bit with APSWEP = No issues 64bit with Reshade = No issues 64bit with RWEPro or RWE2 = No issues Any combination of the above = No issues 64bit with RWE2 with vulkan ticked = No issues 64bit with RWE2 with vulkan ticked + APSWEP = Fog white line issues 64bit with DXVK with or without APSWEP and/or RWEPro or RWE2 = Fog white line issues 32bit will be the same as 64bit results wise. The experimental DX12 build was untested because its broken anyway.
Which route (I guess Castle Rock RR) and weather preset exactly? Let me see if I get this too (or if it's related to your AA transparency settings).
I'm talking about the weather that's selected in that scenario. Edit: It's "EU Storm Snow" from the ELAP. It is not a valid weather for APSWEP, as the manual says. Read the APSWEP manual, it tells you how to change the weather pattern.
I see now. After selecting one of the AP Weather types in scenario fixed that visual bug. Thanks! So to play a scenario I have to swap TimeOfDay files and select most appropriate weather pattern? I somehow thought, that standard weather types should work as well...
Valid weather patterns are the ones starting with "AP..." Plus these and only these which are core weather patterns and are updated by AP (Kuju\RailSimulatorCore\Weather\) - these are used by QuickDrive 0. Default 1. Clear 2. Cloudy 5. Foggy 9. Foggy Snow 11. Overcast 12. Overcast Rain 15. Overcast Snow 17. Stormy Rain 19. Night Cloudy 20. Night Foggy 22. Night Overcast
I might be baiting irony here, but it's the trade off between fidelity and density. And effect quality like shading. Whenever I play such routes I'm like "gosh, that pixelated 2D" for a few minutes, then I get used to it and appreciate the views. To respond to an earlier question, I was commenting because there was a chance that this is not just related to enhancements / weather but based on core behavior. I'm not sure (been a while) but I think those "glowing" trees were on Soldier Summit in a certain winter weather. As you can see comparing OP 1-2 the lines are also somewhat hidden by the fog - the issue is that the edge of the tree line is blended in / outlined against a bright background (white sky) instead of the grey fog. At least on SS that was the issue, flying closer revealed it. The opposite also happens with (bright) grey fog during midnight scenarios where everything is outlined pitch black. If you look at picture 1 closely you can see that the trees right in front of us also have a white outline. You can observe outlining on these two pictures:
I have noticed the problem again, with AP weather this time. With AP Rain Moderate (Fog) preset. When I select AP Rain Moderate without fog - bug disappeares. So it looks like the fog is the cause. I have restarted game, after weather change, as it is advised in AP manual.
You can try to change the AA Transparency settings in your GPU driver which is exactly for this. This is an Antialiasing issue. Also note that Fort Kent uses Low Res vegetation textures if you don't have the 3DTrains HiRes scenery pack. This can lead to AA issues at edges of transparent textures. No issues
Im using 3DTrains HiRes scenery pack. I have even reinstalled it, I was afraid it has been overwritten by Kent route installation.
