Draw distance decreasing in cab

Why when i go in a locomotive cab (or any other train interior) the draw distance decreases? And how can i avoid/change that? It's quite annoying.

This is built into Trainz (presumably because the constantly changing point of view from a moving train requires much more redrawing of the screen than a static view), and yes, it's quite annoying...

This feature was my first disappointment with the software. I complained, and was taken to school by Windwalker about the need for this feature. I still find it disconcerting to ride in cab and miss seeing scenery objects that are not actually that far away. I no longer use cab mode for this reason.:(
 
i have 2 threads for this problem
its not a normal its abnormal

I'm aware of your threads kamran, I'm only confirming that Windwalker posted that it is a feature. Your feature seems to be working a bit too well, however.
 
Seems to be a rather crappy feature:hehe: It annoys the hell out of me to. Especially on long drawn out straights where I should in theory be able to see to "infinity" or the horizon but that is not the case. I am thankful for a route that has a lot of turns because of this.
 
And according to my tests, draw distance (in cab) is limited to 1000 metres for scenery, and to 1500 metres for splines and ground.

Also the stupid edges of map section has a 5000 metres altitude ! May it be, it'll be better to make a "flying island" with greater drawing distance instead of "a giant model table" with especially little distance.

Does Trainztuner help with improving the "In Cab" draw distance.

When setting mine at zfar=_____ (6 miles or more) my framerates almost locked up my carpy ol' laptop.:hehe:

Trainztuner only works in versions up to TC, and the download is unavailable at present.

previously it was quite fine but from last 2 months this problem is annoying and it goes worst when your route has tall building like me so i started new old theme route and track has lot of turns this helps a lot

Yes another trainz "feature" I'm disappointed about too. I've read those posts. Just seems counter intuitive to me but I don't know what's behind the smoke and mirrors in trainz.

I wouldn't switch to dcc for any reason even draw distance. I just don't spend much time inside the cab while in cab mode. Steam is still king on the routes I drive and you just don't get much of a forward view from inside the cab of steam loco anyway. I like the view from outside - usually on the engineer's side and run the loco from the keyboard.

To clear this up.

This is a limitation of the video card technology currently available. You need to complain to the video card manufacturers about this one... Unfortunately, very few games require both detailed interior and a long draw distance, hence they are unlikely to improve this area.

We could give you a much longer 'interior view' draw distance, however this would require us to remove 3D cab views (you would either have an invisible cab, or a flat 2D image to represent the cab). This is not an option we see as being viable, and as such we reduce the draw distance in the cab view instead.

What is the minimum distance to the nearest point of mesh, when the mesh wouldn't be rendered (or rendered incorrectly) to obtain draw distance up to 2500 metres?

Also I can (in the exterior view) to creep under the vehicle wheels (under the vehicle, that is neighbour to one, that is focused by the camera ). They are rendered correctly, and the draw distance is greater than 2500. Any opinion? May it be, to create "floating point of view", that is in front of real camera position, for internal view?

S0 Zec, you said it's a problem with the video card. Then why did we not have any problem with the in cab draw distance in earlier versions of Trainz even with older video cards. Just sayen.:wave:

There is no set minimum. Instead, there's a three-way trade-off:

* Furthest visible object. Any objects further than this will simply not be rendered, ignoring any 'sleight-of-hand' such as the billboard technique.

* Closest visible object. Any objects closer than this will simply be sliced off, and we don't offer much in the way of 'sleight-of-hand' here.

* Rendering 'precision'. This is always better up close and decreases markedly in the distance. Lower z-buffer 'precision' results in an inability to distance-sort nearby objects, leading to flickering- for example, when the track starts disappearing into the ground.

Improvements to any one of those three will always result in losses to one or both of the other two.

Are there any cabin, where the levers are so close to point of view, that they are sliced off? Approximate distance of the closest part in the most cabins equals 1 metre . I don't think, that to obtain 75 cm "sphere of cut polys" is so bad, that you discard a possibility to get it.

Lower z-buffer 'precision' results in an inability to distance-sort nearby objects, leading to flickering- for example, when the track starts disappearing into the ground.
compared to what? The tracks are placed in certain distance from ground, and if you divide 'precision' by two, users will only have to place them in doubled distance. Only!

So please, if you absolute discard the opinion of "ingrained trainzers", add a tag to trainzoptions to change these values. Like -freeincam . I don't think that it is so complicated.

Yea I agree seems to be sorta bogus explanation. Why is it that FSX can have a 3d cockpit with more working controls then any cab in trainz can possibly have and a lot longer draw distance(no not in the air either, you can be on the ground with modded hi-def textures) and see everything rendered on screen outside, and then when you change views into the cockpit you notice no difference in view distance...:o

exactly
even this version is running fine with my this card but dont know what happened suddenly that this thing arise
 
One tweak N3V should be able to do to at least camouflage the problem is to decrease the minimum fog distance. Current slider settings, crank the fog all the way up and the haze cutoff line is a couple thousand meters away, make that closer or increase the fog volume.

Good weather fog set to maximum, visibility 1000 meters;

Move forward and get objects suddenly popping up.

Set for drizzle instead of clear to get bad weather fog;

That's a little better, but still get popups;

Quick and dirty fix, whatever that distance is cut it down to half and make the good weather fog the same. That way objects popping up will be hidden by the denser closer fog/haze/mist and appear more realistically.
