Is it possible to make trees appear further back so they don't pop?

I like having autogen trees in my terrain but I absolutely hate that they pop up so near to the foreground. I would rather have fewer trees but have them appear in the far distance (where they are small) and remain in the scene for a longer period. Is there a way to make this happen? I played with LOD_RADIUS but that did not solve the problem.

Note: my graphics card has 2GB of memory so I presume that it should be able to potentially store a larger scene.

Check your fsx.cfg file and look in the [SCENERY] header.
Find the entry that says SmallPartRejectRadius.  Tell me what the number says.

its doesnt matter because SmallPartRejectRadius was removed from SP1 forward


What he is seeing is normal and the slower the system the worse it appears

Its called alpha fade and they removed it from FSX so the autogen pops in/ot

The only way to extend the autogen radius is the Level of Detail radius and although the autogen may come into the scene further out it wont stop the pop and if you edit the value higher than 4.5 in the FSX.cfg you can expect perf drops



I can run a 6.5 and I use top end high clocked hardware

Yes, I have already extended the LOD_Radius to 8.5 and that works fine in reducing the ground texture blurries without any performance hit on my system. However, it has absolutely no effect on when trees become visible. Without alpha blending, the only way to lessen the sudden appearance is to make the trees enter the scene in the distance when they are just a pixel or two in size.

What I tend to do with my FS 2004 Sim during my low level flights is to generate "Custom Weather" and reduce my visible distance to the more "realistic" 5-10 Miles maximum, (or even less, depending upon local weather conditions).
This then generate a "Haze" in the distance, as one would expect in real life, and the Autogen Objects slowly appear as one approaches them closely enough to observe them clearly!

This makes the Sim Flights more similar to Real Flights up in the air!

...just think...how far can you see clearly into the distance...even on a "Clear" day?...;)...!

This 'feature' is annoying the hell out of me. I just installed Nick's excellent GEX Europe, and apart from giving me great scenery (which makes me want to look out the window more), it allows me to run smoothly at higher settings - except that I've had to crank my AG setting back down to Normal to avoid the forests which keep leaping out of nowhere !

I think I read most everything that's been posted on this problem, and I understand that the real answer - alpha fade - is turned off in FSX and is not fixable by add-on developers (nor, unlike many other problems, will it be fixed by faster hardware). But it really would be nice to find some way of mitigating it. I also tried increasing the LOD radius (to 6.5), and my system seemed to take it, but it didn't seem to help. I read in Phil Taylor's blog on SP1 that FSX batches AG in 2 km boundary. Not sure if that means that AG will start popping up at a distance of 2km (which looks about right), or that everything within a 2km area will pop up together. Either way, I suppose I can understand why changing the LOD radius might not help.

I looked into this problem and there seems to be no method (altering the fsx.cfg or making new agn files) of making the autogen appear further into the distance. I took a plane out and measured using a DME, and it seems to be about a 3.5 km radius however the airport buildings didn't disapear until they were almost 17 km into the distance. So I hand planted the trees as fixed objects (not autogen) and now I have trees in the distance, although it is hard work and it means I only have these trees in limited locations.
