Latest update includes the ability to change the camera size for the scene. This update also comes with a few fixes on how scaling is applied, now you can resize the window and objects should look the same no matter what. This is done by scaling the camera rather than objects. The camera outline should still be used for reference as this represents what the end user will see. If you wish to use this function in your product it will require testing on multiple devices to make sure unsightly blackness is not visible to the end user.
ParticlePlayer asset property guis are in place and ready to be linked up next gui update will include the particle player creation button. Then once particle player is all done the next object to be created will be the TextSprite.
