What happened?

[this doesn't happen with shader turned off at all]

with any shaders on, the trains, tracks, and any immersive railroading-related assets (including landofsignals which also require Universal Modcore mod) will not render correctly.
Like in the screenshot, the very white-washed light contour of the blocks/entities.

Let me know if there's any other information I can give that will help.

You can fix this, when you set enableVBO to false in the immersiveengineering-client.toml :)

it doesn't fix the issue. that is the config from immersive engineering mod, not immersive railroading.
