Raycast to an object behind another object without ignoring raycast
I want to Raycast to a plane which has many objects on it but want the raycast to pass through those objects. However, I want to use OnPointerEnter and OnPointerExit on those objects (to reduce their alpha and make the part of the plane behind them more visible) so I cannot add them to the Ignore Raycast layer. How do I go about doing this?
you could use raycastall which returns everything that is hit. and simply check for the name of the plane. https://docs.unity3d.com/ScriptReference/Physics.RaycastAll.html
If it's they one collider explicitly, you can do a.
collider.Raycast();
where collider is any collider type
That is a good Idea, but what if I am using a custom Raycaster ( which is the case with me )? collider.Raycast() uses the default physics raycaster right?
Not sure what you mean by a "custom raycaster", but if you want a raycast that continues through all colliders in its path rather simply returning the first collider hit, you can iterate through the array returned by Physics.RaycastAll.
