Idea

I agree with @HybridNZ here.
As reported to Jorg, our YPAD scenery suffered many errors after the Australian World Update; the biggest one being that our entire aerial was replaced causing all our aprons and surrounding blends (Grass, Gravel, etc) to no longer look appropriate and appear to be Red.

Our customers are complaining about this and it may prevent them from trusting our products in the future which as a small development company could cause issues.

From our testing at YPAD performance has been drastically impacted, the system I have which is a
i9 9900KF, 64GB Ram & a 2080Ti use to achieve a solid 40+ FPS at YPAD now reduced to less than 15 - 20 at times. When our dev project is opened it runs at 5 - 8 most the time often causing the simulator to crash when attempting to adjust Polygons or Aprons.

I have noticed even with the TIN Excluded the sim still appears to attempt to draw the mesh at a ground level and after further investigation on our project it seems that almost every building we have modeled has a Photogrammetry mesh that is trying to build under it and is flickering with the ground.

I don't know enough about the photogrammetry to say this is why the impact has been so significant in our YPAD release, however I imagine if the sim is attempting to still draw a mesh on top of our already modeled terminal I would think that this is an added load for the sim and many of our users machines.

Look forward to seeing what solution we can have here.

We have been fortunate not to have been impacted by photogrammetry related issues however have noticed that the new bridge for the Hornibrook Highway which seems to be a hand modelled bridge can not be removed using any known exclusion method. We have removed our custom bridge from the YRED scenery to avoid duplication and extra load on GPU for users. Before the world update we are able to exclude the autogen bridge.

I agree, that there should be a way to exclude photogrammetry entirely (from a particular area) for the reasons stated above. Most importantly - custom ortho can't be added above photogrammetry..

@FlyingRaccoon
Any chance of getting this looked at?

I delete photogrammetry on my airports all the time with polygons and set Buildings/Exclude TIN.

Yes, this has been introduced in SU9 as a new tool. We have since edited all of the effect scenery and will release when SU9 is public.

It's not new, but that's great :)
