Workflows for Virtual Worlds/Virtual Reality

These are some notes I'm taking to remember how I got some things to work for student projects.

Scenario 1: Importing 3D Models Into Opensim

Correcting Collada Model Errors

First time I spent money ($15!) on a 3D model to use there was an issue. The snow leopard was inside-out; the texture was on the inside and the outside was transparent. I learned after much searching that the "normals" had to be recalculated, which can only be done in a 3D program. The download included an FXB file so I used Blender, imported the FXB file, went to Edit Mode > Mesh > Normals > re-calculate outside normals which flipped the orientation of the faces to outside. Then I exported that as an OBJ file. Then I could import into Opensim with Singularity viewer. I chose File > Upload Mesh > High detail. It comes in gray so change the color to
