i got this square with a purple (instanced) material on it.
when i change the color of the material instance by tweeking the color parameter i made, the reflection on the wall does
n’t update immediatelly. it only changes when i manually drag the new color material from the content browser onto the square.
Note: it does automatically update in other places, so without having to drag the new color of the material instance on top of the square again.
As you see in the picture below, the color updated automatically on the wall on the left of the square, but they didn’t update on the corner part of the wall over the square (shadows )
some help would be greatly appreciated
