Texturing both sides of a face

Did something slightly similar to this with the same problem showing up.
Start with a cube primitive, delete all but two faces opposite each other.
Scale it so that the faces meet (aka are back to back).
Now I can only select one of the faces.
Go back to the scaling operation and move them apart slightly and I can select both faces fine.
These two faces do not have any edges in common (unless you do some optimizing behind my back).

I am using ver 7.1.1.3 and downloaded all the addons and the latest plugins.
I used to be able to texure both sides of a face..IE am building a caboose and need to texture the inside,but cant find anyway to do it now. I have far more pluggins in the plugin folder than what shows up in 3DC. Any suggestions.

There’s a bug related to this currently. I haven’t got to it yet, but it is a priority. You may have to be creative to select these faces. For example, select an edge, right-click and choose ‘Select-andgt;Faces’ and then de-select the faces you don’t want. It’s a hassle I know. I know the solution to the problem, it’s just a matter of writing the code to fix it.

Ok Thanks Richard

I’ve had a look at this now. I’m not sure I’m going to have a solution anytime soon. It may be a DirectX problem. I may have to upgrade DirectX versions to solve this.

Paul does similar picking, I think, in his viewer, so I’ve asked him (in his bug report) for more information. Maybe he’ll know a solution for it that I can’t figure out.

One thing that you can do instead of using the ‘double side’ plugin is to copy and paste the object you want as an interior and then use the ‘invert’ operation on it. That way the interior and exterior remain separate objects and it should be possible to pick the interior. You’ll need to move the interior’s group position to the exact same position as the the extrior (via object properties). This is easiest done if the interior and exterior are children of the same group.

I tried this myself and it worked fine. After moving the groups to the same position, I moved the interior object to the same group as the exterior.

An update: Paul doesn’t do this sort of thing in his viewer so he couldn’t help.

The suggestion I had does work well. It’s not as fast as the double-side, but works better for a number of reasons, in my opinion.

An interesting thing about all of this is that many modelling programs don’t allow more than two faces to share an edge. ‘double siding’ results in four faces sharing an edge. Allowing this leads to a bunch of ‘exceptional circumstances’ in processing algorithms and makes processing slower. But, it’s handy to be able to do ‘double siding’.
