Strange conical "circus tent" artifacts..

Postby caliberza » Sat Jul 11, 2015 3:33 pm

Heya,

I've compiled FG from github and I'm noticing some strange conical artifacts like huge "circus tents", basically just around KSFO, haven't seen them anywhere else.
Attached screenshot demonstrates this:

I'm using Ubuntu 14.04, I have an Nvidia Gtx550ti.
I realise of course that github is development version so some issues are to be expected, I'm just not sure if this is one of them or if it's something with my setup..

Any ideas appreciated. :)

Looks like a rembrandt problem around the lamppost's at KSFO. Probably it will disappear when you disable rembrandt. But further I don't know how to solve it :oops:

I tried disabling rembrandt now, it made no difference. ;/
I also tried switching pretty much every other graphics option on/off and none of them seem to fix it.

Set the Model shader to zero, all the way left.

Thanks, but this doesn't appear to fix it either.

Tried, no luck. :/

I should perhaps mention that on closer inspection this problem is not purely visual, what I mean is that if I fly into the conical shapes they are solid (i.e., I crash :lol: ) I can also taxi over them like going over a hill..

I'm pleased to say that I've gotten it working.. it would appear that there is something amiss with the default scenery files in the github. I suddenly had the notion to enable terrasync, and whatever it downloaded around KSFO has solved the problem. :D

FlightGear isn't hosted on Github. Our official repositories are on Sourceforge. Maybe you've used some corrupted repository clone? See http://sourceforge.net/projects/flightgear/ for the correct repositories.

My bad.. I did indeed pull it from Sourceforge, I guess I'm just so used to git using projects being hosted on github that I kinda forgot where I pulled it from.. :oops:

Hi,

I've seen the same thing today after deleting the ~/.fgfs cofiguration directory and then running FG with TerraSync disabled on the command line. Some objects were reported missing from FGData in the logs - this information is key (if you can copy and paste it, that'd be extremely useful). I might look into it later.

Regards,

Edward

@bugman: this really should be looked into ASAP as not everyone is going to or be able to run terrasync... not as long as the data packages are as huge as some of them are when considering the time it takes to download them and the time it takes a craft to cross the boarder from real terrain to langolier territory...
"You get more air close to the ground," said Angalo. "I read that in a book. You get lots of air low down, and not much when you go up."
"Why not?" said Gurder.
"Dunno. It's frightened of heights, I guess."

This is a piece of cake to reproduce!

Code: Select all
$ rm -rf ~/.fgfs
$ fgfs --disable-terrasync


It doesn't matter if the FG_SCENERY environmental variable is set. I see the circus tents as KSFO. The console messages are:
