Dude, you have gotten help. Right now you have been told what the issue was, you said you did exactly that and it still doesn't work. So what should we do? Come to your doorstep and have a look at your computer and your rF modding setup in person to track down whatever issue you have? We need a bit more information or all we can do is guess. So you have changed the material names and exported your .gmts again. If you're not exporting directly into your ModDev folders, have you copied the new .gmts to your working directory after exporting? Do you even have a working, correctly linked .tdf file for your track? Have you re-exported all objects containing the materials you have changed? rF only loads a material once from the first object that contains it.
I renamed the materials so they use a prefix that's listed in the TDF like I showed in the attachment on the previous page; hit the Export button and loaded the track.
There are millions of rF tracks out there, and millions of tutorials on how to build a track from scratch. I do not see the point here. BTW can you explain me what is the problem, exactly? Are you following the new Real Road technology? Are you using correct naming on materials and on .tdf? Are you using correct road mesh exporting settings?
I wonder, do you have any loose GMT files in your main TRACK folder? That would prevent the latest exported GMTs from being loaded. There's no reason why the polys would suddenly not be rendered, whether they're listed in the TDF or not.
No, that's not what Luc meant. Could you tell us your folder structure in the ModDev? Is it something like: \trackname\ ..with .tdf and the ...Icon.dds file? \trackname\configuration\ ..with the .scn, .gdb, etc. files? \trackname\Assets\GMT\ ..with all the gmts? \trackname\Assets\Maps\ ..with all the texture files?
Mate, it NEVER works as it is. There is just one object with all those stuff in the same istance (road, walls, gravel areas, sides etc...) and there is not polygon structure, just edges. The entire road mesh is composed by 4 polygons... View attachment 2324 Are you sure this is the same stuff tested by Luc?
