Shadow problem and improvements

Hi!

When i use an fbx 3d model, it doesnt cast shadow over the floor, i saw it works (some times) with GLB, but ir did not cast shadow over the image target. 

At the momento Spark Studio, which is free, is a better solution for AR. Would be great to have particles, multi image targets, materials, textutes and light control as Spark.

About some other topics, would be nice to be able to loop a sequence of animations, not only them individually.

Geospacial sometimes works, some times not. I had a test at a park and it took a long time preparing, after that it would stay forever on the pan around screen, not working the AR. Sometimes it works perfectly and othertimes the objects keep moving with the camera.

Would be nice be able to save the project, not export, as there is an option to open project.

For last i had someone test an AR experience on iPhone and he had to download the Aero Player.

Adobe Aero Geospatial Pre-release Guide (V0.5) say "Viewers do not need to log in to the Aero app OR have it installed to view experiences."

It would be very important for a lot o people projects that the experience could be played without Aero App in Android and iOS.

Sorry for the long post.

Thanks
