I suspect that the bug relies in the inizialization of the Realistic Scene Node, but I can't figure how to solve the problem:
Code: Select all
RealisticWaterSceneNode* realwater = new RealisticWaterSceneNode(device->getSceneManager(), 640, 480);
realwater->setPosition(core::vector3df(0, 0, 0));
realwater->setWaterColor(video::SColor(255, 0, 0, 255));
realwater->setWindForce(10);
realwater->setPosition(core::vector3df(0, 0, 0));P.S. Here is the full code:

texture. The terrain renderer loads it and creates the 3D terrain from
it.
To make the terrain look more big, we change the scale factor of
it to (40, 4.4, 40). Because we don't have any dynamic lights in the
scene, we switch off the lighting, and we set the file
terrain-texture.jpg as texture for the terrain and detailmap3.jpg as
second texture, called detail map. At last, we set the scale values for
the texture: The first texture will be repeated only one time over the
whole terrain, and the second one (detail map) 20 times.
