Hi there,
I am creating a rain streaks effect and I’ve got the problem that the Texture only aligns to the flat texture.
Is there a way to make the texture always align to the same direction so the streaks are always running down and not, depending on the UV, upwards or sidewards.
You could use a world aligned texture for that. If you look in the particles content example, there’s a material function for doing something very similar to what you describe. I can’t remember what it’s called, but it’s used on a lot of the assets in that demo.
EDIT: I think it has the word “drips” in the name.
I’ll try this. I’ve also stumbled over the local aligned texture function which might be better for player characters to avoid texture swimming but these two have one common problem: how to connect texture samples to their input. It seems like they only accept texture objects but i need samples because the texture gets panned and resized.
