I have just looked at the image in Nuke. There is an alpha channel as part of the file but the channel is completely empty. Nuke and Fusion don’t do any to apply the alpha channel to the image when they read it in, they just us it for other operations. After Effects multiplies the image to the alpha, so if it is empty your image disappears.
You either need to create an alpha channel that matches your image when you render it from your 3D app or make sure it renders without an alpha channel at all, so just RGB, not RGB+A.
You can easily use this image without an alpha channel. If you put this over something as it is it will work like an ADD blending mode.
