• 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.

FSX GMAX Material ID's

I have multiple planes that were made for runway markings. The planes have the textures applied as UVW mapped, and scaled/positioned within the scene. Everything looks good in FSX.

For performance reasons, I would like to have ALL the runway marking texures on multiple texture sheets using the UVW Unwrap.

The problem I'm having is that when I select all the planes to be mapped, I only get one poly that is showing in the UVW unwrap editor, after assigning all the planes with a material ID. I understand the Box and Plane object types have there own material id's selected. So my question is how do you do this? Is it to late since I already assinged the planes with UVW mapping? Can this be done?

Thanks
 
did you assign the same material ID to each poly, or a different one?

I'm struggling to figure out what you meant by: "For performance reasons, I would like to have ALL the runway marking texures on multiple texture sheets using the UVW Unwrap."
 
There are a total of 4 Planes that I would like to be on one texture sheet, and I have 2 diffent textures that will occupy 2 of the 4 planes.

I selected 2 planes which share the same texture as ID1, then selected the other 2 planes with ID2. I assume when the planes are selected, they turn to red?

I did watch the video tutorial that Bill W. made explaining texture mapping, but it for a BOX not a plane.

What I mean by "Performance reasons" is I do not want to have lets say 20 .DDS texture files in my texture folder, I would like to combine them to lets say 5 or 6 textures. So its easier on computer performance while running FSX.
 
Sorry, about previous reply. You replied almost the same time I did.
You need to make multimaterial in FSX.
All you need to do is making two material and applied to the object you want.
You have to choose the polygon ID= 1 then apply material one.
Then choose polygon ID=2 and apply the material two to that polygon. Those two polygon has to be in the same object.
The the multimaterial will be automatically made.

You cannot choose mutimaterial in Gmax since it will come out the FS9 material only, not FSX material.

OK, that makes sense, I will give this a try.
Thank you.

Just an update to this problem...its working correctly jtanabodee
