When I try to build my structure in tool, it says: ### ERROR couldn't update edge #1985 (red). It gives me this error for three other edges as well. I selected show open edges in 3ds max, and it doesn't find any. Could someone tell me what I did wrong and how to fix it?

Also, could someone tell me how to display the model and wireframe at the same time in max 2011?

Hi Noobyourmom!

Usually the error “couldn’t updated edge # (red) occurs after using tessellate. Tessellating one face or group of faces will make new vertexes that are not connected to vertexes to other faces. Remember Halo’s engine requires your map to be a sealed system. That means that all vertexes have to be connected together forming the faces, or polygons that make your map. To find the errors, open your map in 3ds or gmax. Then click on the utilities icon, click on “MaxScript”, than choose whatever plugin that you used to make your jms file. Now click on a button that reads “Imort Wrl”, A navigation window will open. Navigate to the Halo CE parent folder and look for a file for you map. “Example file will look like your_map.wrl” click on it and it will import all of the errors for your map that were found while Halo CE tool structure command was ran.
Next click on “Select by name” and choose one or all of the errors in your map. That will show you were the errors are. Look for vertexes that are not connected. Delete the faces that have vertexes that are not connected, and remake the faces. Making sure to not miss any vertexes.

After all faces are remade, remake your jms files re-run the structure command and repeat process until all errors are fixed.

Let me know if you need more help.

I hope this helps.

Thanks! Got it working.
