Hi. I am drawing a series of lines in the world and everything is going well except the lines are not visible when they intersect water (as with solid blocks)

I have the following code:

@SubscribeEvent
public static void drawLast(RenderWorldLastEvent event) {
    renderMyLines(event.getMatrixStack()); // Draws lines perfectly except when they are underwater (and I'm not)
}

@SubscribeEvent
public static void drawSelection(DrawSelectionEvent event) {
    renderMyLines(event.getMatrix()); // Draws lines perfectly, even going underwater - BUT! ONLY when I'm looking at a block!
}

Is there an event I can use to render my lines such that they will be drawn correctly, even underwater and regardless of what I'm looking at?
I've searched through the code for forge hooks/events (especially LevelRenderer.renderLevel() where these events are triggered) but can't seem to find anything close to the above.

Many thanks.

Sorry for bumping this, just hoping that someone might have an idea for the right way to do this. Perhaps Forge needs an additional hook?
