Here's how to create a 32-bit TGA file with an alpha mask which you can use for your Billboard texture:http://tutorials.robbiegee.com/ps_tga.htm
In your 3D modelling application place a plane so that the base of the plane, i.e. the midpoint of the lowest edge, is centered at 0,0,0, switch to a Front
camera and make sure the plane faces the camera. Apply the texture to the plane and make sure it is positioned correctly on the plane before you export it to Lumion.
In Lumion, add the Billboard
material to the plane. If it turns invisible, it means that the plane is facing away from the camera instead of towards it. To fix this, turn it 180 degrees in your 3D modelling application and re-export it. Then use the Re-load model
button in Edit material
mode to update it.
If the plane turns into a line after you apply the Billboard
material to it, it means that it needs to be turned 90 degrees.
