I’ve tried creating a “Sun” with Directional and SpotLight to no avail - specifically the shadowMap of the Sun - the normal shadows on materials that take them work as expected.
All the tutorials I’ve found have had huge, static suns. I want mine to follow the player. But tracking the player position with the Light position doesn’t do it … the shadowMap does not seem to move, so the shadows disappear eventually.
I tried a lot of things and it just feels like a needle in a haystack.
Setting the Light.position to player.position, nope
Setting the Light.target to player.position, nope
updating shadowMap position along with player and light position, nope
An extreme example of what I want is, to make a 10 unit area tracking the player constantly casting shadows… any pointers?
I did get this working with Spotlight, enough.
Still no luck with DirectionLight.
With SpotLight I set the Light.target once to the player model at intialization, and then inside the animation loop, update the Light position a fixed offset from player.position… I assume a “player.model.add(spotlight)” would also work there. I thought target was a fixed internal vector (“back to origin”), but it refers to an actual world object it seems.
Docs suggest that a DirectionLight “position” is a normalized vector, but if thats the case, why are we updating it in the anim loop… it’s confusing, idk.
Not sure what the deal was with DirectionLight but I really just wanted a simple sun for now. And these are really simple - the spotlight offset and FOV has to be far away for this work, which is making it pretty blurry
yes. and figuring out how to do it was not simple. e g 1st thing I tried was to add the light as a child to some object, and you know how that went, right… but I was surprized.
