Hello, currently I try to create some poses, which I want to export to Second Life. Related to this I have two questions. I work with Blender 3.5 and Avastar 3.1. I use Firestorm as Second Life viewer. First question: I try to create a lying pose. Therefor I placed the avatar in Blender to the ground. After I exported the pose to an .anim file and imported this file to Second Life the avatar is standing or rather flying. The first screenshot shows the pose in Blender: The second scrrenshot shows the pose in Firestorm: What do I have to do, to create and export a lying pose in Blender, which will be seen as a real lying pose in Second Life? Second Question: The fingers of the avatar are spread, when I add it from Avastar. I changed the position of the finger so that they look more natural in Blender. After I exported the pose and imported it to Second Life the finger are still spread. It looks like I didn´t made any changes to the avatar. What do I have to do so that the changes to fingers will show correctly in Second Life? Thank you in anticipation and best wishes Pflasterstrand
