@emmanuel001: You can use the gif in 2D view(as Resource Image). In 3D, it is not currently supported.
Just curious though - what is the use case for the 3D gif?
Thanks for the answer, I have an image of a mashup and I want to show it as if it were in real time, it is only demonstrative but i need show in the 3D area in a monitor laptop
@emmanuel001 Unfortunately, at the moment you can show gif stuff only in 2D view. Using it in 3D will make it appear as a static 2D image without the real feel of gif.
