--- Comment #5 from Lorenzo Ferrillo lorenzofer@live.it --- No I'm following that bug also.
That functions are used only with Oblivion Reloaded installed. But this bug happen also on vanilla Oblivion, with a builtin function.
I explicitly said to ignore the fixme:d3dx:ID3DXEffectImpl_* State capturing not supported, yet! ,et,etc, becouse they are caused by another bug, and only when a specific OBSE plugin (Oblivion Reloaded, that is a graphical enancher) is installed.
Also I'm currently using last dev version with the preshader implementation by Paul Gofman. It doesn't fix this bug.
