b4 into game,i use

device->getVideoDriver()->removeTexture(ui2dimg);

but scene always show 2dui & menu.

how to clear out all 2d texture & menu gui?

now, i know how to clear out gui menu
guienv->clear();

but i unknow how to 2dimage clear out scene

2D images? did you mean textures?
textures are managed by the IVideoDriver.
you don't need to wory about them.

ui2dimg is ITexture*

maybe i can't clear deliver oneself of idea.

the 2d picture is menu's background.

when i choose some game, i need clear out currently all background & menu.
i use device->getVideoDriver()->removeTexture(ui2dimg); remove 2dimg,but,scene always show the 2d background.

draw2DImage is driver-level rendering, and is not a GUI widget. Try using IGUIImage.

giuEnvironment->clear();
?.......................

If you don't want to draw ui2dimg, you need to avoid calling driver->draw2DImage(ui2dimg, ...). The easy way would be to write something like this...
Instead of removing the texture from the texture cache, you would write this...
Even easier would be to use an IImage.
