Road face problems

[Joh]

Hi all, i have a problem when i load the desert map on the editor everythings work fine, when i use the example on leadwerks wiki it load the map cprrectly but when the camera goes near to the street some face of the road flick and goes away (probably under the terrain).

Do you know why?

I can't show images right now because i am from the mobile.

Here you can see the image. As i told this doesn' happened on editor and i simply copied an pasted the code on documentation (lua an bmax)

Any idea?

[shadmar]

You could try increasing the offset just a bit to 0.01

 

from the road_node.lua it should be :

class.roadoffset=0.005

[Joh]

This seem don't have any effetcs, i don't see this error when the camera is far away.

[Joh]

The three images show you the issue..

This happened ONLY using this code (not in the editor) that is token by the documentation..

I just tested on my office pc and had the same result.

Is there anyone who have the same issue?

 

This evening i will try a fresh install.

[Joh]

Also compiled from another pc and same weird result..

[Joh]

Josh just a question, which version of bmax you used to compile?

[Josh]

It's 1.45, but that's not going to make any difference.

[Joh]

Found a workaround i simply raised a bit the road.

Do you "fix" the y pos on editor? I really don't know what think, anyway seem ok for the moment.

[Josh]

No, but the script has a slight offset. However, it should behave the same in your program as it does in the editor.

[macklebee]

It never has (as is shown from the multiple returns from searching for the term 'roadoffset'). Bmax and standalone lua scripts (and i assume c++) have always required an adjustments to the 'class.roadoffset' value.

 

To get it to work, you have to do certain steps.

1) Open the road_node script, change the 'class.roadoffset' value to 0.055, and save the script

2) Open up the scene (SBX) in the editor, click on the 'Rebuild Roads' icon in the editor toolbar, and then save the scene (SBX) in the editor

 

Now load that saved scene into your program and it should work as this works for me now and for the past two years - keep in mind that you might have to update files in your project folder, like the map, the road node script, etc, if they are separate from your SDK files

Thanks mack, i'll try this.
