Black rim in multipass

Hi,
I've got a issue with a black rim around my player's sword...
it only appears in multipass mode, and I don't know why.

Any suggestions?

it looks like you're drawing the sword in EarlyZ mode with different matrix

Actually I didn't even use Early Z *shocked*,
//Edit: or is it used by default, if I render with world.draw() ?
But I figured smth. out:
I rendered the sword in the overriden draw method of my player, if I render it in the "main" Render method (with RM_SOLID) it works all fine...
Any idea why this happens?

I don't understand, please post where exactly are you rendering? in what rendering modes, and with what matrixes?
(code would be nice)

At the time I saw the black rim, I rendered in the player class (game::chr) in the draw method.

Code:

void draw()

{

    __super::draw();

    //... (draw armor)

    OrientP& hand_r=cskel.getPoint("HandR");

    Matrix m;

    m.setPosDir(hand_r.pos,hand_r.perp,hand_r.dir);                                             

    Meshs("Obj/item/weapon/sword/0/0.mesh")->draw(m); // render item with matrix

}

Now the draw methode is called by Game::World.draw if I inserted the player in the world editor.

But now I changed the part, where the weapon is rendered, to this (moved into Main.cpp/Render):

Code:

void Render()

{

    if(Kb.b(KB_I))    //wireframe

        D.wire(true);

    Game::World.draw();

    D.wire(false);

    switch(Renderer())

    {

        case RM_LIGHT:

            LightDir(-!Vec(-1,1,1), Vec(0.45f)).add();

            break;

        case RM_SOLID:

            OrientP& hand_r=player->cskel.getPoint("HandR");

            Matrix m;

            m.setPosDir(hand_r.pos,hand_r.perp,hand_r.dir);

            Meshs("Obj/item/weapon/sword/0/0.mesh")->draw(m); // render item with matrix

            break;

    }

}

This method is called by Renderer(Render), in Draw!
So I think Game::World() did something with my sword internally which I didn't wanted... :-\

please notice that in the second codes you're rendering the sword only in RM_SOLID mode

while in first codes you render the mesh all the time (in all modes), please use switch(Renderer()) in the first codes too

yeah, ok, I'll do, thank you!
