• 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.

Keep sharp edges (avoid anti-aliase)

Hi all

How can we keep the edges of one object equal to the model and avoid the anti-aliase activity?

This bridge have sharp edges on those blocks:

Modeling sharp:

But at simulator, the anti-aliase do this:

How to avoid this?

Are you sure you have cleared any smoothing in the polygon properties?
 
Thank you for the feedback.

I don't see any option on the polygon that do that, but my acknowledge is not so much:

Some wrong detail that I'm not seeing correctly.

Hi,

The way I get to it:

1. Where you have the blue highlighted Editable Mesh in your image above, click the little black + just to the left of the words.
2. In the list that rolls down, choose Polygon.
3. Choose Edit/Select All (selects all polygons), or select the polygons desired to be unsmoothed.
4. Scroll down the display below this word Polygon, until you find the section called Smoothing Groups.
5. Click the button called Clear All.

The smoothing should be removed and you should now see sharp edges in GMAX and in FS.

As I see it, you have sharp edges showing in Gmax, but they're all smooth in FSX and you don't want the column tops to show that way. First you need Gmax to show the modelling accurately, so right-click at the top left of the viewport and select Smooth + Highlights. You'll now see your model like it will show in FS with the smoothed geometry showing smooth.

Then follow tgibson's advice above.
 
Tom,

I was wondering about that myself, but (I think) his last pictures show that they are indeed smoothed in GMAX, but GMAX and FS are displaying the smoothness somewhat differently.
 
The original picture showed the facets (no smoothing shown), so I assumed that viewport was set to Facets display. Been there, got the teeshirt and the red face to match...

This looks like that work.


Below the difference with one with and another without.

Thank you Tom and thank you all.
 
Hi,

Glad to help. If you know you do not want an entire object to be smoothed, for most basic shapes when you create them there is a Smooth checkbox somewhere in the rollout. Uncheck this (it's checked by default) to unsmooth your shape right from the beginning.

Ah, faceted view (right click the view name, Other/Facets and Highlights), I didn't think of that. Good thing to remember.

Hope this helps,
