View Full Version : Original Aircraft LOD problem?

Take a look at the original IL2 aircraft in the game (109,IL2 etc.).

As you approach one from distance the LOD (I think this is the term that applies?) changes in distinct steps.

This would help if I could post pics, but what I am saying is there are about three or four distinct steps of model detail as you see the aircraft come closer/move away. Try it

- go to a flyby view of a 109 and watch the detail levels clearly change, then try it with a spit, you will see the difference.

All the latest aircraft make the LOD transition smoothly. Its a bit of a problem, not only does it suck to look at, but it also makes spotting 109's etc A LOT easier!

I thought this comment deserves its own post, but without screenshots I can understand if you dont understand what I'm saying.

Havn't really thought about that.. I'll have a look.

It's been an issue ever since the first release of IL2. The clunky LOD changes in the early 3D models are a result of much stricter poly count limits on the early models (incidently IIRC there are 6 LOD models for each plane). As the poly counts are significantly higher on later models, the transitions can be made to appear much smoother.

Short of rebuilding the entire LOD set for each affected model (hundreds of man hours for each model) there is no cure. I doubt we'll see it in this game engine, but look for huge improvements in BoB http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif.

thanks for the info Tully, I have been aware of this issue for some time and figured if it was fixable it would have been done by now.

I have no doubt BoB will be our saviourhttp://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

Yeah, thank heavens for it. So people with 'lesser' PC's can play it as well. http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

We have learned to live with it as it makes it easy when you fly 109's most of the time http://ubbxforums.ubi.com/images/smiley/16x16_smiley-happy.gif

I'm afraid that's not entirely true http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

The polycount for far LODs in the newer models is still very close to the original IL2. After all you only need a few polygons when the aircraft is that small.

It's simply a problem of scale. The original modelling guideline for IL2 stated that the far LODs should be made bigger for easy spoting!

Most new models since FB have properly-scaled LODs, including the Gladiator, of course http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif
