• 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.

trees what do I do wrong?

Hi all,

I built a scenery using EOD to make my future house (Inchala! Ojala!) and wanted to adapt the scenery as much as possible to the real world, meaning I have to seed the scenery area with mediterranean shrubs,olives and pines. I used the existing possibilities but the outcome is not really 'natural'. I used Arno's textures, but they only work well if you do not downsize the autogen trees. Therefore I decided to make my own lifelike trees. Unfortunately the result looks like this once I converted the files to DTX1 adding a white alpha channel:

What do I do wrong?

The z-test is set incorrectly. What you are seeing is the filtering causing your alpha to not be 1-bit on the edges.
So when you Z-Write this alpha, the areas that are not purely white or black (because of the bilinear or trilinear or anisotropic filtering) Z-write through everything all the way back to the sky behind all of the scenery.
You can fix this by setting the shader to Z-write alpha and then Z-test the alpha at a value of GREATER than 128.00. That's a good generic setting for 1-bit alphas.
If you want to pull the alpha in closer to the trees, you can raise the Z-Test value. Lowering the Z-Test value will make the alpha pull away from the tree (make the tree bigger).
 
That Z-test story is for FSX only :), so not really valid for FS2004.

But it seems you solved the problem now?
 
Hi Arno,

Yes I did and I didn't. I had used DTX3 instead of dtx1 and by using the white color for the alpha channel I managed to get rid of both white and/or black branes or whatever you call it. But only if you are very close to the tree. Allow me to include one more screenshot to show you what I mean:View attachment 3711
How can you change that?
