• 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.

GMAX and big problem with "mirror" Function

I open this post to try to solve this annoying problem that have with the "Mirror" function of gmax.
I try to explain you that happened to me.
I state, although surely you will know as using gmax is one of the first things you learn, that in Gmax one side of any figure has a single face .. as in the example below, is known as the square of orange is "solid" one part, but fully transparent from the opposite side.

I say this because it has to do with what is my problem and I'm going to show below.
To explain I create a cube and apply different textures for each face so as to have
In opposite to F
And opposite to B
C opposite to D

Now if I click on the Mirror function, I create a clone of my cube that is perfectly in gmax reverse the copy (as if it were precisely mirrored) of my cube.

Now look what happens when you export it (happens to be using those plugins fs2002 and FS2004)

Practically the cube obtained by the mirror function has the faces "solid" looking internal toward.. so for example .. A side face A being the solids towards the center, it appears clear to me and shows me that its so F Once he has also the solid face towards the inside .. so unlike the original all solid faces are turned towards the interior and transparent to the outside ...

Do you have the same problem? How can I fix ... sometimes the mirror function is essential
 
<sigh> I wish I had ten cents for every time the "Evil Mirror Tool" is brought up! This is very well-known among the FS modeling community and has been discussed - and CUSSED - for many years now. For example, this is the third time in less than a week that this has come up in a post! :yikes:

Without getting into the details of why this feature of Max/GMax fails in flight simulator, let's instead simply mention how to achieve the desired goal without problem.

The solution is to add a "Mirror Modifier" to the object's stack instead of using the "Mirror Tool" on the upper toolbar... :D

Now if you are trying to repair something that's already been abused by the Mirror Tool, here is how to fix it:

  1. Select the mirrored object
  2. Click on the Mirror Tool
  3. Add a "Mirror Modifier" to the stack
  4. Collapse stack to E-Mesh or E-Poly as desired
This essentially reverses the bad action and then applies the good action... ;)
 
I would be happy with 5 cents for each time it is mentioned. That would already make a good revenue :D
 
Sorry .. I'm brand new to fsdeveloper and gmax and I'll definitely still crap .. luckily we have a community well prepared .. I'll try to do as has been suggested (before I'll try to figure out how to do the actions you desribe ..) for now thank you.

I don't understan how apply "mirror modifier " ...i know only mirror function.

It's just another modifier and work the same, look in the list. right hand, modifiy, modifier list, don't worry, the joke is true, many people have problems because in the logical way they use the mirror tool from the top menu but for fsx is not good.

Click to expand...

On the right side of the Max/GMax viewport, there should be a menu like that shown in the screenshot below. The area boxed in red is the Modifier List. Click on the "downarrow" to expand the list, and choose "Mirror" from the list.

This will place a "Mirror" modifier on the object's operation stack which is identical to the Mirror Tool's operation except that the Mirror modifier does not alter the normal's vector sum, but leaves it as +1.0.

The Mirror Tool inverts the normal's vector sums to -1.0, which is why it looks so weird in FS!

And to fix it use Bill's trick - use the Mirror BUTTON again to flip it back where it started, and THEN add a Mirror modifier to the stack.

Hope this helps,
