Pe-2 Wings and Fuse are both half done (modelling). I checked the polycount - oups - all in all about 480 (no stabs, rudder, canopy, gear, etc.). I would say the both wings (with engines/props) will have about 350 triangles. The fuse will also have about 340-360 triangles. The rest could be about 200-400 tri´s. In the end close to 1200 tri´s (worst case), seems to much for me (the Ishak outside has 500 or so in high detail). The fuse is actually build up out of 10-sided cylinders, I could rebuild it with 8-sided cyl. but that would look a bit crappy.

I could try to export most of the parts as quads. But it would be helpfull if you (the planebuilders) can tell me how many tri´s/verts whatever would be good for the Pe-2 and how much you´ve used on your plane.

The BF109G's most detailed LODs has about 1000 polygons(not triangles). This is excluding the cockpit which you can not see if you are more than 5 feet away.

The other versions of the 109s and the 190s ranges from 700 to 900 polygons. The Zero has about 750 polygons.

Why triangles? You can cut your polycount in half by using quads.

I read that quads could make trouble sometimes. But 1000 tri´s should be possible (/2 =500).

If the quads are not coplanar they may not be visible from some angles when viewed in SDOE.

I think it is just the coolest thing that the weird green cigar thing in the pic Laika posted is going to be a plane someday. _sigh_ I can't wait!

This is correct, but I would add this... as long as the quad isn't way out of whack, you can get away with a certain amount of non-planarity (is that a word?). Very few quads on the P-47 are perfectly planar.

1200 sounds quite reasonable for a bomber Laika ! It'll be great to get a FPS friendly bomber I'm glad you are being stingy with the polys.

I agree with JT.. try for the quads it helps the frame rate a lot and I can't see much visual difference in my yak using quads or triangles.

LOD usage is, I think, even more important than watching your poly count. You can have a low poly plane that will still cripple the framerate if you don't use LODs. Imagine a plane that uses 500 polys... now put 10 of them on screen and you have a problem. One rarely has multiple planes on screen and very close, but when planes are far away, it's most often the case that you'll have many on screen at once.

Hey JT - step by step - I allways start with the highest detail LOD´s. I plan to do 4 levels for this plane, so that high (or very high ) detail will only be shown when you´re extremly close (outside view etc.). Unfortunatly it is not posible to reduce the polys for the fuse by vertex welding, so I had to model the 2nd detail lod from scratch again. Much work !

So long

Indeed much work... and texture mapping all those LODs is easily the most tedious and painful aspect of plane building... easily my least favorite aspect of Openplane.

I texture map only the high detail lods, and before I weld them down to medium and low res I detach the single elements (different textured like "top of the wing" and "bottom of the wing" etc.). Now the mapping coordinates will not get lost. After that just attach...

High detail LODs do make a big difference to frame rate .. try flying the B17 with the cockpit zoomed out while flying in formation

The "weird green cigar" looks slowly more like a plane ! Not ? Dont mind the wrong smoothing it is not finished yet ! I hope I will end with <=1000 faces (tri´s).
