Cel. 1.6 rc1: extras-standard models not found from extras

[selden]

In Celestia v1.6, Mesh objects which are defined by an Addon in extras-standard are not found when they're referenced by Addons in extras. They should be.

For example, when the SSC file below is placed in extras, the ISS model is not drawn for the object "1998-067a"
(For this project, I am comparing several different orbit definitions for the ISS, so I can't simply use a Modify directive. User addons shouldn't be put in extras-standard, since it is intended for objects defined in the Celestia distribution kit.)

I'll be adding this to the bugs tracker on SourceForge.

Interesting! Where are the users told that they should do that? When and why was that decided?

If you do something like this, then you have document it somewhere, so the user knows about it. Especially a new user that is for the first time adding an addon.

So, please put that advise in the README.

Best regards,

ChrisL made that change a while ago. I think he should write about it. He won't be able to respond for a few days, though.

I was also confused by this setup, but the standard placement of add-on
components in the normal "extras" folder still works as it always has.

At least as far as I have been able to determine.
