Weapon Shadow not Casting

[0bytedna]

Hello guys,
I am developing a true first person shooter game for OculusVR.
I successfully implemented full-body awareness.
I implemented custom weapons as well. The only problem right now is that the weapons are not casting shadow.

Here is the screenshot:


My Pawn Class

	if (bFixedView)
	{

		out_CamRot = FixedViewRot;
	}
	else
	{

		{
			CalcThirdPersonCam(fDeltaTime, out_CamLoc, out_CamRot, out_FOV);

			GetActorEyesViewPoint( out_CamLoc, out_CamRot );
		}

	}
	return true;

	// Handle the HeadMesh visibility
	if (HeadMesh != None)
		HeadMesh.SetOwnerNoSee(!IsVisible);
}

simulated event Vector GetPawnViewLocation()
{
    local vector viewLoc;

    // no eye socket? No way I can tell you a location based on this socket then...
    if (EyeSocket == '')
        return Location + BaseEyeHeight * vect(0,0,1);

	
	SetMeshVisibility(true);
	SetWeaponAttachmentVisibility(false);

    Mesh.GetSocketWorldLocationAndRotation(EyeSocket, viewLoc);
    return viewLoc;
}

	{

I USED UTWEAPONS LIKE LINKGUN AND ROCKET LAUNCHER..SHADOW STILL NOT VISIBLE...IT MEANS PROBLEM IS WITH MY PAWN CLASS??

I HAVE NO IDEA WHY SHADOW IS NOT CASTING FOR THE WEAPON!!! NEED HELP!!

SPRINTING LOGIC SEEMS TO BE BROKEN AS WELL

[garner]

I have a weapon class that casts shadows, the difference I see between mine and yours is that I have assigned a light environment and a collider. I can't say if that's the problem it could be anything, but if you do a search for bcastdynamicshadow=true in the development directory you should pull up many working examples of skeletal meshes that use dynamic shadows. Look for differences between yours and the ones already in the directories.

Nope ...didnt work...i added DynamicLightEnvironment...still no shadow...wat the hell is wrong...why is the shadow not casting...??

Hey,
You using AnimTree in your weapon class. How do you play animations from AnimTree in your weapon class? Is it extending from UTWeapon?

[garner]

I tried out the code you gave and merged the default properties of the code I sent, it seems to work.

Animations play on the skeletal mesh, just make sure it has the animtree an animsequence to play the animation and the animset. There is some adjustments that need to be made to the below code, but all you should need is to playAnim() on the skeletal mesh.

	


	PlayCustomAnim(weaponData.animName,weaponData.bLoop,false);



simulated function PlayCustomAnim(name animName, optional bool isLooping, optional bool playBackward){

	PickupMesh.PlayAnim(animName,,isLooping,true,,playBackward);

}

Weapon Shadow is now visible....but it screwed up other things. MuzzleFlash and Animations are not working anymore. If i switch to third person view (BehindView), everything works fine, even the MuzzleFlash, Animations and Shadow. How do i get the MuzzleFlash and Animations working in FirstPerson View now??

[garner]

The reason is most likely the commented out first person mesh code in the defaultproperties, which were commented out because I don't have your assets.

Yea...maybe....so how do I get the things working properly now?
