Decal streched

Hi! Im using decals actors for make a bullet holes but sometimes the hole is stretched, anyone knows why?

that’s just how decals work when you give them 2 dimensional information. they project a 2d texture in a specific direction. typically with bullet holes you just rotate the decal to face the wall by reference the hit normal, inverting that by multiplying it by -1, and getting the rotation from x vector.

in other situations you can either mask out stretched areas by referencing the world normal. other times you can use 3 dimensional information like a spheremask and world aligned textures.

Oh i understand now, thank you so much, that helped me a lot!
