Is there any way of adding user information in any form to polygons?
If not can I request this as a feature please ?

The only way I can see at the moment would be to make each polygon an object and add a comment or tag.

I'm trying to edit levels of a game engine that requires each polygon to have (32-bit) flags associated with it.

I've converted the levels to dxs file format but can't see a way round this problem.

Any help or suggestions appreciated.

User info per polygon... I can see the advantages in a level-editing environment but this is the first time it's being requested. Does anybody else see the usefullness of this?

Perhaps a plugin for this would be an idea... Wink

Maybe a workaround would be to use the material editor for that and to assign a second material (color, inactive) to the polygons. Materials have user info tags, too.

A plug-in could be done... IF the plug-in interface allowed us access to the sub-selection level :-)

Ideally, you'd also allow data per face (and per vertex) to be persisted with the object, and go away/get cloned based on user interaction (i e, more callbacks to the plug-in).

What I do when I need these properties (for collision, triggers, etc) is tag them with a special material (texture) and then map material to surface properties outside of DeleD.

Think this would be great! Razz

It could help alot in collision detection. You can build a very nice level with Deled, but without collision detection it will be quite useless.
being able to mark specific polygons as "solid" will make creation of collision hulls much easier.

This is also usefull when you use shaders Smile

I think you can do tons of things with per polygon userinfo, and i like the feature to be implemented. Wink

For exactly that purpose I would definitely choose to use a specific material (copy of the original material with _solid in the name and custom properties to recognize it), as Mr Fletcher suggests. I'd probably make it stand out visually too, to make it easier to recognize.

Managing individual polygon properties is a pain (as a rule of thumb, any object that contains more meta data than actual data is usually a bad sign Very Happy

). But enough whining and complaining, if we stumble upon a nice way to blend this into the GUI we might implement this really soon, because there is real reason why this shouldn't be possible. Very Happy

Thanks for the material layer as polygon flags suggestions.
I hadn't noticed that disabled layers appeared in the dxs file.
Should make some better progress now Smile

Would adding a "tag" command to the polygon editing menu
that allowed a string or integer to be assigned to all selected polygons work for the GUI ? Very Happy

Shh, don't tell anyone, but I kinda implemented it already. I'll post screenshots when I get to it later today... Wink

There you go. Available from 1.71 onwards, polygons now have a tag /user properties:

No final date on 1.71 yet, but I'm sure it won't be long...

Neat! How do you access that in the XML exporter interface? Do I have to ask for it specifically, or will I get it no matter what?

You'll get it no matter what, it's an optional <tag> inside <poly>.
