Terra assert at update

[Nickak2003]

When I call terra update with 0 epsilon, I get the following assert and am unsure why:

Code: Select all

HlmsDatablock::~HlmsDatablock()
    {
        assert( mLinkedRenderables.empty() &&
                "This Datablock is still being used by some Renderables."
                " Change their Datablocks before destroying this." );

I have a single directional light and if i change epsilon to >=1 i get no error, but cannot change the light direction either.

Can you post the callstack when this happens?

OK, on closer examination, there is an Ogre::Exception being thrown and the earlier error was that I didn't shutdown terra or something correctly. However, I don't know what is causing this exception either:

Code: Select all

  
#if OGRE_DEBUG_MODE
        {
            uint32 currentFrame = mVaoManager->getFrameCount();
            if( mLastFrameMappedAndAdvanced == currentFrame )
            {
                OGRE_EXCEPT( Exception::ERR_INVALID_STATE,
                             "Mapping the buffer twice within the same frame detected! "
                             "This is not allowed.", "BufferPacked::map" );
            }

Here is the callstack:

OK, so the problem was that update can only be called in an "onBeforeRender" function, you cant call it x times without actually calling render.
