Getting CFrame Rotation from Raycast.Instance

[Lunaryis (Bluey)]

Hi, how do i get the rotation of a part from raycast.Instance?
I’ve tried doing this then converting it to CFrame.Angles

if raycastResult then
            local oX = raycastResult.Instance.Orientation.X
            local oY = raycastResult.Instance.Orientation.Y
            local OZ = raycastResult.Instance.Orientation.Z
            local anglesCFrame = CFrame.Angles(math.rad(oY),math.rad(oX), math.rad(OZ))
            local part = game.ServerStorage.Ore:Clone()
            part.Parent = game.Workspace.Ores
            local newCFrame = CFrame.new(raycastResult.Position + Vector3.new(0,2.5,0))
            part:SetPrimaryPartCFrame(newCFrame * anglesCFrame)
            CollectionService:AddTag(part, "Ore")
            game.ServerStorage.TotalOres.Value += 1
        end

But when the part spawns, it comes up like this (sometimes)

It works fine on flat surfaces btw.
I’ve also tried .FromOrientation but that messed things up even more.

Are you trying to align the rock with the grass? Directly copying over the orientation of the ground to the rock won’t work because those are global rotations and depending on how the model was constructed it can have different results

oh yeah here’s a thread i found that probably addresses all of your questions

Orienting a part to the ground normal?

Hi everyone. I’ve been trying to make this work for a few days now to no avail. Basically I’m trying to orient a part CFrame to the normal of the ground beneath it. The end result is a custom Go kart framework. Like shown in this video. In the video the guy basically did four raycasts downward and then averaged the normals of them. That’s not a big deal, and I think I’ve got that part down ok. local downNormal = Vector3.new(0, -1, 0) local _, _, leftFrontCast = findPartOnRay (workspace, newR…

Yeah, they are using the deprecated raycast, any idea how to do this with the new raycast? I know how to get the hitPos (raycastResult.Position) but i have no idea how to get hitNormal.

local rayResult = workspace:Raycast(origin, direction * length, params)
local pos = rayResult.Position and rayResult.Position or origin + direction * length
local normal = rayResult.Normal
