Thanks Laurent works fine now

hi

I had a look at that section of the track and noticed track segments 167 to 170 which partly looked not as straight as they could. I selected 167, clicked the move-button (F6) ("Force 16 feet distance" checked !) and slightly wiggled it, and did the same to the following up to the "problem corner" and noticed them nicely straighting out. then the track looked still about the same, but the cc-line was scrambled from that corner, which is very suspiciuous. I deleted all sectors after the corner from cc-line sector 19 onward (so 19 was still there), and ... it loaded

you may want to go around the whole track the mentiond way, starting at s/f. that way you are sure, the track is as "straightend" as it gets, and all segments ar 16 feet.

I hope it helps

That solved it, thanks Addie.

Got some objects into the gp4 now, have a query regarding sloping though.



Is it possible for me to have it sloping down (Z axis) from 3.569 at the far end, to 0 nearest to the screen? I can't find a simple method for doing this. I think I could do it through the vertices', but wouldn't I have to do it one by one then?

Hmm, you can do that with influency distance on.
To use that, get to vertex level as if you wanted to move a vertex and select one of the vertex that will move the most (I assume it's one of the closest of the screen).
Then go into Preferences, Computation Tab, Vertice options.
Check ignore altitude (if not done yet) and sinus option. Then input slight less than the length of your road (if your road is 24 segments long, then it is 24*4.877m=117m, set it to 115m)
Move your vertex as usual with move mode on and right mouse button to move it on Z axis.
If everything is done correctly, you will see the slope created in realtime

you might need to make some tiny adjustments as "left" and "right" vertices of the road won't be at the exact same altitude but most of the job is done

PS : .dat sector have a feature to apply perfect slope at will through the multiple sector edit window (and Track Profiler for refinement). Then you can convert .dat to .gp4 to get the 3D mesh.

Thanks for that Lo2k. I've got to the Preferences menu, but can't see a 'Ignore altitude' checkbox anywhere under any of the three tabs?

Edit - Done it!

Yep, it's because it's an incoming feature :p (not that useful for your task though)

Quick question, whats the value to change which side of the pitlane the cars are on? I remember reading about it somewhere but can't remember where to find that value...

Edit: Found it in initial sector settings.

Never realised the second value under "Corrects pit lines" corresponded to which part of the track they head to upon leaving the pitlane! Changed it whilst looking for above with interesting

Completely seperate problem, whilst driving in the pitlane all ai cars move their steering wheels side to side very quickly, what causes this?

@Truecrysis : What do you mean by "corresponded to which part of the track they head to upon leaving the pitlane". In original tracks, I can only see -16384 as a value, not a sector number or such...

Such behaviors could appear if you didn't fix cc cars behaviour in Action menu or if you have some sectors that are not 16 feet long... For one track, none of these worked and only rebuilding the pitlane fixed it...

It seems i can't replicate it the way i want to... I changed a value somewhere and it seemed to force all the cars to head straight to the right of the track as soon as the left the pits...

Hmm maybe its due to the fact i constructed the pitlane completely using sector position/orientation rather than adding sectors in the right place, so a lot of them won't be 16 feet long. In that case it's not too much of a problem

Steer, you can try to set the CC dir value at the sector box of a pitlane sector to 0. Do this only at sectors which are straight and not curved.

My Grand Prix 4 Files
I'm a total dick. How many people can say that?

Just found out that the "Camera" and "Unk2" settings in the Object Attributes window are related somehow.

They must be both zero or both not zero for objects to appear correctly. If one of them is zero but the other is not, the object does not appear correctly. I didn't experiment with values different from what original objects have, as Unk2 doesn't make any sense yet.

as far as I know "Unk2" is "visibility set" related, which seems also related to the cams somehow. best results so far I had with deleting all visibility sets but the last and zero all values there, and zero all "unk2" and "cam" object attributes.

Hi there chaps.
I'm tantalisingly close to being able to release my track, but I have a problem with it in wet weather. The wet track surface is only visible ten metres or so in front of the car when going uphill. When going downhill there is no problem. The flag for the track bits is set to 64, the wet reflection box isn't ticked but at a lot of the original tracks it isn't either, and the camera is 0. Any ideas what the problem might be? When I set the flag to be 0 (wet reflection ticked) the track is transparent and I can see my scenery underneath it, as I built the dat over my land, instead of my land around the dat.

Here's a picture or three...

so its dry in front of the car, but as soon as you are there, its wet ..

hm, strange thing

thats OK, because actually the tarmac is where the reflections of the other objects show up. so the tarmac itsself does not reflect.


> and the camera is 0.

thats OK too. 0 means kind of "all track side cameras"

just for a test, of course be sure to have a backup, if you replace your tarmac by one made by "track from .dat" ? (in the "convert .dat track"-window clear all checkboxes except "tarmac", and choose an appropriate texture) ..

but anyway, I'd rather suspect the *_track.bin file ...
if you open that file in the gp4builder, it looks "as expected" (compared to original files) ? normals all normal ? and if you recreate that .bin ?

maybe it helps

if I remind well, any .gp4 object property is useless as GP4 uses the .bin file. (wet tarmac marks are some kind of jips after all)

Thanks for your help addie, and Laurent too
So following your advice, i've tried the following...
I've deleted all track objects in the GP4 and recreated them from the .dat but that didn't solve it.
I recreated the .bin, but that didn't work.
However.. I have been deciding whether to use a skydome or not. This problem only came when I deleted the skydome. Putting the skydome back in the .GP4 solved it. The wet bin displays correctly. How strange!
So I guess I'll have to use the skydome, and lose the dynamic weather. Never mind!

indeed !

well I really like the dynamic weather, so I could not live with that
there has to be another cause. if you like, I also could have a look at that ...

Thank you addie, that's very kind of you
I'll try and figure it out first beforehand, it might be something silly that I've missed

What's the full name (class and name of the object) of your skydome ?
Can you capture the GP4Builder object window with skydome properties (with position, base...) and paste it here ?
