Hi,

I've recently started implementing Havok into my game and I've run into an assertion that I can't seem to figure out. The error is as follows:

.CharacterControlStateMachinehkpCharacterContext.cpp(64): [0x6D4ABE44] Assert: input.isValid()
Invalid character input

Which seems weird to me, considering the following code I have constructing the input:

hkpCharacterInput input;
hkpCharacterOutput output;
{
	input.m_inputLR = -move.x;
	input.m_inputUD = -move.z;

	input.m_wantJump = want_jump;
	want_jump = false;
	input.m_atLadder = false;

	input.m_up.set(0, 1, 0);
	input.m_forward.set(unit->direction.x, unit->direction.y, unit->direction.z);

	input.m_stepInfo.m_deltaTime = dt;
	input.m_stepInfo.m_invDeltaTime = 1.0f/dt;
	input.m_characterGravity.set(0, -30, 0);
	input.m_velocity = characterProxy->getLinearVelocity();
	input.m_position = characterProxy->getPosition();

	hkVector4 down;	down.setNeg4(input.m_up);
	characterProxy->checkSupport(down, input.m_surfaceInfo);
}

// Apply the character state machine
characterContext->update(input, output);

I tried release mode to see if I could find any behavioural errors, but everything seemed to work as expected.

What's causing the assertion? Is there anyway to get more info on that? I'm using the latest free version of Havok.
