Post by: Martin on February 22, 2013, 09:59:17 AM
I have this scene. (https://www.dropbox.com/s/ugb71pi662wm870/Udklip.PNG)

I can not scatter the objects in a right way. I have a mesh which is correct in meter size. But I cannot scatter anything with forest pro. I get this huge "F" which normally use to be small. What can ce the problem with my scene.

I have imported this mesh from microstation into 3ds max as a fbx file.

Very frustrating that I cannot find the answer.

Have you tried to Xform reset your plane ?

Maybe this helps

It also may be a problem with the surface's normals. If the XForm reset doesn't work, try applying a Normal modifier as well.

In any case, if you don't solve the problem, please send us the surface and we will check it.

Normal worked. :-)

What does this modifier.?

It reverses the Normal vectors of the surface, this is a common issue on imported surfaces.

PD: There is a Normal vector for each face of a mesh, and it is perpendicular to the face. Commonly is used to define the "Front" and "Back" sides.

I actually have one mesh which I still gives me problems. I have first applied xform and then normal modifier. No luck.

What is the right way to import from microstation to 3ds max. I have exportet as a fbx file, and that seems to be the right way (except these problems).

Can anyone help me with a step by step guide after exporting from microstation (fbx) to correct this file before working with it, because it seems that the file is
pretty messed up.

I have saved the one mesh which I can not get to work if anyone would like to see.

Also I have the direct export from micro. (fbx)

I have not experience with Microstation, but i think FBX should be the preferred method. Sometimes it is not possible to avoid these problems, regardless of the importing procedure.

Please, send us the mesh to support@itoosoft.com. We'll take a look to it.

Hi
I have examined the scene that you sent us, and I see that the surfaces have reversed normals. For some unknown reason, does not work the usual procedure of selecting the faces and apply a "flip". However, if we convert surface in "editpoly" instead of "editmesh", we can select all the faces and apply the "flip". After this, we can do  the normal procedure.

OK. Thanks. I will remember this. :-)
