Please note:
- On D3D (and maybe older OGL?) you can no longer manually set mipmap data when enabled
(for example mips from image loading will be ignored).
- On D3D (and maybe older OGL?) texture locking for mipmap levels usually won't work anymore.
- On new OGL this flag is ignored.
- When disabled you do _not_ get hardware mipmaps on D3D, so mipmap generation can be slower.
- When disabled you can still update your mipmaps when the texture changed by manually calling regenerateMipMapLevels.
- You can still call regenerateMipMapLevels when this flag is enabled (it will be a hint on d3d to update mips immediately)

To make Irrlicht run inside the custom window, you still will
have to draw Irrlicht on your own. You can use this loop, as
usual:
\code
while (device->run())

driver->beginScene(video::ECBF_COLOR | video::ECBF_DEPTH, 0);
smgr->drawAll();
driver->endScene();
}
\endcode
Instead of this, you can also simply use your own message loop
using GetMessage, DispatchMessage and whatever. Calling
IrrlichtDevice::run() will cause Irrlicht to dispatch messages
internally too. You need not call Device->run() if you want to
do your own message dispatching loop, but Irrlicht will not be
able to fetch user input then and you have to do it on your own
using the window messages, DirectInput, or whatever. Also,
you'll have to increment the Irrlicht timer.
An alternative, own message dispatching loop without
device->run() would look like this:
\code
MSG msg;
while (true)
{
if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
if (msg.message == WM_QUIT)
break;
}
// increase virtual timer time
device->getTimer()->tick();
// draw engine picture
driver->beginScene(video::ECBF_COLOR | video::ECBF_DEPTH, 0);
smgr->drawAll();
driver->endScene();
}
\endcode

do it how you like. */

\endcode
Instead of this, you can also simply use your own message loop
using GetMessage, DispatchMessage and whatever. Calling
IrrlichtDevice::run() will cause Irrlicht to dispatch messages
internally too. You need not call Device->run() if you want to
do your own message dispatching loop, but Irrlicht will not be
able to fetch user input then and you have to do it on your own
using the window messages, DirectInput, or whatever. Also,
you'll have to increment the Irrlicht timer.
An alternative, own message dispatching loop without
device->run() would look like this:
\code
MSG msg;
while (true)
{
if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
if (msg.message == WM_QUIT)
break;
}
// increase virtual timer time
device->getTimer()->tick();
// draw engine picture
driver->beginScene(video::ECBF_COLOR | video::ECBF_DEPTH, 0);
smgr->drawAll();
driver->endScene();
}
\endcode
However, there is no need to draw the picture this often. Just
do it how you like. */
