When trying to upload a tree i made in Blender 2.75a. At very beinging when upload the Tree a Red X pops up saying i am missing Triangles and Vertices (Note: I made sure it was Mesh and Subdivision in the actual tree), wich later disappeared when file fully loaded i guess. Then the tree in secondlife showed up on the Preview image as the tree but With no texture when i put texture in it, and afterwards when trying to calculate it a Error pops up saying, MAV_Block_Missing. What can i do to fix this situation?
