Irrlicht Engine

I place make makeColorKeyTexture() inside render loop, the memory leaks very obviously, and this problem both exist in OpenGL and D3D9 driver.

I have a big terrain that represented by a TIN (triangulate irregular network) and many contour lines. I currently using a SMesh to contain TIN as indexed triangles, and using another SMesh to contain contour lines as indexed line-strips. when rendering, the contour lines always shows above TIN ...

I have created a Render To Texture used for render a fixed camera's view into it. In render loop, every time I call makeColorKeyTexture() to make background color of RTT to transparent,then call draw2DImage() to paste RTT onto screen. But I have a strange problem: if I call makeColorKeyTexture() in ...

I have a big terrain that made up into many triangles, and have a FPS camera used for walk into terrain, and have another camera fixed above terrain used for RTT(render to texture). the RTT has been pasted into screen.

I want to RTT's background is full transparent, so using:
video::IVideoDriver ...

thanks for your reply. I have write my track animator, that can exactly control camera's position and rotation based on time-key-frame interpolate, the camera always fly with uniform speed and smoothly rotate.

thank you very much, I will try again.

I have many points that served as a track, and I want fly camera follow this track with optional offset, and require camera's direction always toward the front (the track point's tangent direction).

currently, I use ISceneManager::createFollowSplineAnimator(), that can control camera follow track ...

I have a empty node, and have many animationed mesh nodes include in it, but when I call getBounds(), it always return unit aabbox, not include any child's aabbox.

So, have any functions can get a node's aabbox (include all child's)?

thank you.

thank you very much, i will try to fix it in my code temporarily, and wait for v1.7 release.

1. For texture mode:
For a material layer, I want to set texture wrap mode in u and v direction with different values, how to do? currently, seems must set to same value, because no method to specify which direction should be changed.

2. For texture direction:
In OpenGL, if I set a rectangle's ...

In lastest svn version of Irrlicht engine, the IrrCompileConfig.h:

#if defined(_MSC_VER) && (_MSC_VER < 1400)
# error "Only Microsoft Visual Studio 7.0 and later are supported."
#endif

should change to:

#if defined(_MSC_VER) && (_MSC_VER < 1300)
# error "Only Microsoft Visual Studio 7.0 and ...

1. IMeshManipulator does not support mesh that using 32-bit index, so, for dynamic mesh with 32-bit index, IMeshManipulator will almost crashed.

2. the skybox and skydome node using same node-type-flag, so when the scene save and reload, the skydome will become skybox. Also, skybox and skydome node ...

yes, when set cameraoffset to (0,2.0f,0), then seems ok.

when I load a saved scene, the FPS camera missing origin settings for animator, the skydome missing it's mesh and just hang on the space.

Now, for FPS camera, I can set my scene::ISceneUserDataSerializer pointer to save and reload extra parameters, and set it to animator.

But for skydome, I must ...

thank you very much.

when I set the radius of sphere to 2.0 and CameraOffset to (0,0,0), means that camera located in the center of sphere, and always 2.0 above ground? But when I does so, the camera seems cling to the ground.

I set radius to 2.0, because the height of man about two meters, and ...
