Object disappear when moving

Post by giulioz »

I want to import a 3d model from a SCO file (Big Rigs - Over the road racing) using a custom importer.
I wrote a code that loads the vertices, the indices and the texture coordinates from the file and fills up a MeshBuffer.
I can render the model but when I move the camera from (0, 0,0) the object disappears.

Even with

Code: Select all

camera.FarValue = 9999999999;
camera.NearValue = 0.001f;
buffer.RecalculateBoundingBox();
mesh.RecalculateBoundingBox();
sceneNode.SetMaterialFlag(MaterialFlag.BackFaceCulling, false);
camera.AutomaticCulling = CullingType.Off;
Can someone help me? Thanks in advance :)

Possibly the camera is not facing the node anymore?

Possible check. Set node debug info to see bounding box then draw line from camera position to either node position or just down camera target vector to be sure what you are looking at?

Test if culling is responsible by disabling it for you node with setAutomaticCulling(irr::scene::EAC_OFF).

You probably forgot to set the bounding boxes, both for mesh buffers and the mesh itself. This leads to these problems.
