• 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 grass texture and transparency

Hello,

I am working on a grass object, which I will place at the taxiways and runway.

But I have a little problem at the moment. My grass object is transparent, but blue, the grass, which normally should be green, is blue too, like the transparent part ob the object, but visible.

So I try to describe my object and texture config.

3ds max:

SrcAlpha
InvSrcAlpha
AdditiveNightOnly

Z-Test-Alpha: 58

Alpha Test Mode: Greater

Z-Write Alpha: on

PSD file:
Green Grass with black background.
Alpha ~ 70%

then convert to dds DXT 5.

Hope anybody like to help me with this problem.

Thanks

comy
 
That not working, worse, now I can not see anything and I am not sure about reason, in cause of try and error strategy :rolleyes:

But z-test alpha to 128 didn't work right.

Maybe you or anybody likes to have a look in the files. I wouldn't exclude, that the problem is inside texture config.

Thanks for help

regards comy

Try Z-Test level 70-75, that works for me when I used semi-transparent textures for grass, 128 is mainly for DXT1 alphas (pure white/black)
 
Comy,

Your alpha map has to be a mask, showing just the grass and masking the background.
Try the attached image.

I have converted your dds back to bmp to have a look into the file. I think I understood it :) thanks
