Blender Export Now Requires -Z forward Y up plus Experimental

After the update of 9/8/17 we must do exports out of Blender differently than in the past; And in spite of the fact that Blender's axis is Z up and Y forward: We should not have do such odd things in Blender to make it possible for Sansar to get an attachment to land in the right place in relation to the avatar. We should be able to export the model from Blender the way it was creates with the Z axis up which is the way Sansar is oriented. But Sansar still will not allow for the Z axis to be imported as up. In Sansar we build with the Z axis up just as we do in Blender. So, where is the difficulty?

And we now must use a Blender setting called !Experimental! Apply Transform. I have already applied all transforms in Blender so that the orientation is 0.0.0. What does this step actually do? There is no remaining transform to be applied.

  Tried a simple test of a small cube the same way I used to export an attachment, sure enough won't work now due to the AABB

  In the past, the Blender export axis had no effect on how the object was oriented in Sansar. Now that this Blender setting is taken into account it should be a simple matter to get Z up in Blender to match Z up in Sansar.

  This entire process should not require the creator to do something wrong in Blender to get it right in Sansar.

  We have been discussing this for months and now it has gotten even worse than it had previously been before this update.

  here is the fix in the unity wiki with example code that maybe sansar team can look at fixing this.

  aside the axis orientation you need to actually rotate the object -90° on the x axis, apply rotation AND then rotate it back by 90° on the x axis, cuz otherwise Sansar will check the file and think its out of boundaries. XD
