• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

P3D v4 Default Autogen Objects suppress Autogen Trees (specifically the ag_telephonepole)

I've stumbled upon an issue that seems to exist only in P3Dv4. I don't think I've encountered it in other sims.

Any autogen I create which has but a single default autogen object in that cell (specifically the ag_telephone object pole; found in Scenery\Global\scenery\autogen.bgl; GUID: 46f3d6cb-4270-4373-aee9-89fb38462ea9; default.xml reference: 960b0c53-4824-d848-e7ea-3e9475d18c29) causes all trees in that cell to disappear. Buildings and other autogen objects remain unaffected.

Above you can clearly see the one cell on my island of Barbados which does not contain a telepole.

This is the same autogen object since FSX. It has remained unchanged. But as far as I can recall, this does not occur in previous sims. Has anybody encountered this and found a potential solution?

The only fix I have for now is to remove all telepoles from my scenery autogen, which is a shame.
I could just create my own telepole object and add it to my custom autogen (which would probably also save some polygons) but that's low priority and I'd still like to figure out why this is happening.
 
Hi,

I have made some scenery using that object before as well, I can try to load it in P3D and see if I have the same results.
 
No, I have been on vacation the last week. And I'm not behind my machine with P3D now.
 
Hi,

I checked the scenery I made before, but the telephone poles are still there.

Are your autogen trees custom or default?

I'm wondering if its some sort of conflict with my trees. But I've checked that there are no conflicting GUIDs, MDL format is FSX and DDS format is DTX5, so i'm really not sure what else to look for. :scratchch
 
The trees use default models.

Do you have custom tree models or just custom groupings?
 
Hi Mousy:

I do not have P3Dv4.x to test with, but have you checked the 'active' Terrain.Cfg to verify whether the "individual" Telephone Pole object GUID is cross-linked with a vector Autogen 'meta-object' which includes that Telephone Pole object ?

For example: Telephone Poles typically are 'linked' via a custom definition in Terrain.Cfg to a vector Autogen 'meta-object', so that they automatically appear along the side of certain CVX vector Road objects also placed by that 'meta-object'.


I mention this based on a possibility that it might explain custom Autogen display failure if a Telephone Pole GUID is used.


If a line of multiple Telephone Poles is placed incidental to having placed a roadway via a vector Autogen 'meta-object', the total count of Autogen objects may exceed the threshold limit of "Autogen over-saturation", and may result in a failure of any Autogen to appear in scenery areas.

This is a rather obscure and over-looked consideration which is sometimes a factor in troubleshooting Autogen issues.
