Hi,
Does Capture support single side rendering / backface culling of imported 3D models? I haven't found a solution to this myself and I'm guessing the answer is no. If so, could it be implemented? Would be much easier to navigate in models that have a ceiling.
Yes, capture does this by default. You can use the 'Doublesided' property in a material to set a material to be either single side (which will then be culled when viewed from the rear) or doublesided.
The Doublesided setting in the material properties does indeed control whether backface culling is applied. In order to understand how it works, it's important to know that every polygon in a 3D mesh has a front face and a back face. If the back face is pointing towards the camera, it will be hidden (culled). Whether the face is considered front or back is determined by the direction of its normal. You can easily adjust the normal direction of each face in a 3D modeling software, such as Blender. It may sound overwhelming, but having the correct normal direction is essential for proper geometry and material display.
