Should be fixed in 2.1

I still want to warn that some visual errors may occur (red and blue highlight blocks, as well as lines may change brightness (a little), depending on the viewing angle), however they are in most cases not significant (and I can't do anything about it, since Schematica uses glVertexPointer and quadVertexBuffer for rendering and not Tessellator.addVertex, but I was able to get them to (at least) render))

Of the significant issues , I noticed that sometimes a water shader applies on the highlight blocks, but this is an exception for a couple of shaders (only noticed with Sildur's Enhanced Default ), if you use BSL then everything is fine

By the way, in 3.0 this will be fixed completely, that is, without changing the brightness at an viewing angle or applying a water shader.

So the fix will be complete (3.0 coming soon™)
