Repeating the issue: Summon this actor near a wall.

function PostBeginPlay()
{
    local Texture T;
    local Scorch S;
    local Barrel B;

    S = Spawn(class'Scorch');
    T = S.AttachDecal(1000); // Get wall texture.
    Log(T); // ScriptLog: <Invalid GetPathName 00000001>
    S.Destroy();
    S = None;

    B = Spawn(class'Barrel');
    B.Skin = T; // No crash yet.
    B.Mesh = LodMesh'Nali1'; // Nali mesh for animation.
    B.PlayAnim('Breath'); // Crash.
}

S.AttachDecal returns invalid texture. Invalid texture: Invalid GetPathName 00000001 Crash is caused by mesh animation.

Using D3D9 renderer. You need to summon actors like in code quite a lot to cause the crash. Decals=True in Unreal.ini

Fixed. C++ code tried to return AttachDecal result as a boolean, but UnrealScript expected Texture pointer.
