• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Neither layers nor Z-bias make a difference on my skid marks **confused**

Good day folks.

Good to be back developing after being absent for a while.

I'm trying to convert this FSX poly to P3D and I have an issue trying to figure out P3D2 ground polys. Neither Z-bias settings nor layers seem to have any effect on my materials in the poly.
They are supposed to be ordered as follows: asphalt/concrete base, asphalt/concrete detail, runway markings, dirt-grunge layer, skidmarks.

For some reason it all works well except for the fact that my markings appear above everything. They are semi-transparent, and as such you can see the dirt and skidmarks through them, but they need to be on top.

I have tried the GP wizard in FSX mode, in P3D2 mode, I have altered zbias levels, but nothing seems to alter the look in MCX or P3D.
At one time, I changed the Destination Blend of the base asphalt material to Zero, and magically, the skidmarks appeared correctly, but I cannot for the life of me seem to replicate this success anymore. No idea why this worked for a minute.

Can anybody offer a suggestion as to what I may be doing incorrectly?

The link below is a zip file containing the model, textures and the MCX .gpw file that I use. The runway is supposed to appear at TGPY.

Hi,

In the GPW the layer settings are used to set the zbias of the material when exporting in P3D v2 mode. In the other modes they set the layers in the FS2002 style code. Both approaches should actually work well.

I don't have P3D (re)installed yet on my laptop after I upgraded, so I can't test. But I notice your MDL file already seems to be curved for the earth (it's not flat at zero). That might be part of the problem. The GPW expects flat polygons as input.
 
Ok guys, I made some headway but I am stumped again somewhere else.

I managed to get the skid marks and dirt looking exactly how I want them to look in MCX by setting No Z-write to True and by changing the destination blend and source blend of the relevant textures to Zero and One. These were all successfully saved into the P3D mdl file (see attached zip).

I then ran the mdl through the GP wizard for P3Dv2 and got my BGL. (Re-open the BGL in MCX and all appears perfect).

Open the airport in P3D2.5... no markings, no skid marks, no grunge, no detail textures, only the base layer of asphalt and concrete. (Wuuut?)

Could someone check out the attachment and let me know what they think? (Texture files can be found in link from the previous post)

PS. Arno, I started with a fresh build of polygons so there should be no curvature present in the MDL.

Hi there, Mousy. Any progress? Been having the same problem myself on my current project, but after much testing and failing, I figured that not all vertices were even on the Z-axis. Make sure all the vertices are on _Exactly_ the same plane before you export the model.

Hi Finn. The polygons have gone through the GP wizard, so they all come out on the same level. This is confirmed when the bgl looks fine when re-opened in MCX. However P3D displays differently.

Hopefully somebody can test my files within P3D and tell me if they are able to reproduce this.
