How do you want the transparency in the PNG to work?
There are two options currently supported by Lumion:
1. used to mask/clip areas of an image. Use Custom --> Standard Material and the slider Reflection/Clip/Bright
. This uses a 1 bit pixel recognition to make the pixel transparent (like chroma-keying), used for example to remove single colors such as background of an image such as in a 2D person billboard.
2. mask/make any area of an image transparent according to the level of transparency/alpha channel set in the image editor. This means any part of or pixel can be not fully opaque. Use for example in semi-transparent lead-light windows. Use Glass Material, set Texture Influence high and Transparency to something less than 1. The Glass Material is currently the only material to support 8 bit transparency. Textures generally need to be either PNG, TGA, TIFF or DDS.
The problem is that when we are animating and creating the scenes or even flying around the models the png texture seems to dissapear from camera, like the camera has a short range for png texture.
So, as you are using the clipping of a texture in the Standard Material, the texture is disappearing when seen.
Note: there is no feature in Lumion to set the transparency level as in the 8bit transparency of Glass for the Standard Material. This has been discussed and in the user Wishlist.
