Thanks Andrew for the suggestion. Here is the pic of the changed decal projection, Blueprint. I actually tried this first but was unable figure out the Roll value.
So now the decal is projected perfectly onto any surface normal. However, Now I need to rotate the decal to match the direction of my white Arrow by inputting the “Roll” value to the decal. I’m still having issues figuring out the blueprint way to do it.
I appreciate any further help you can provide on this! Thanks!
