FBX general export issue of 3D model for Unity

[Anonymous]

Hey guys, I'm currently working on a project, where I need to import a 3D model of a mammoth into a Unity project. I'm no graphics designer and just downloaded 3ds max yesterday, so bare with me please.
The mammoth is from the following website: https://www.turbosquid.com/3d-models/3d-max-mammoth/969283 . The 3D model consists of a two max files (called vray and fur), severall textures etc. For more detailed information
see the description on the website.

I managed to open the vray.max file in 3ds max. I added the VRay Plugin but couldn't add the Hair Farm plugin since there is no demo version for the 2019 version of 3ds max (tried the version for 2016, but threw an exception).
This is how it looks in 3ds max with default shading in perspective view (and no hair):

Nevertheless I tried to export the model as a Fbx file, however I'm getting the following warnings:

1. One or more objects in the scene has local axes that are not perpendicular to each other (non-orthogonal).
   The FBX plug-in only supports orthogonal (or perpendicular) axes and will not correctly import or export any transformations that involve non-perpendicular local axes.
   This can create an inaccurate appearance with the affected objects:
   -ElephantLLegDigit01
   ....
2. The plug-in has detected one or more animation controllers that cannot be directly supported. Using the Bake Animation option may better address these limitations. The following nodes are affected:
   -Elephant
   -ElephantPelvis
   .....
3. Some materials in this scene may not be supported by certain applications and will import as standard gray materials instead. The following materials are affected:
   -03 - Default
   -Material #2
   -06 - Default
   -12 - Default
   -mammoth
   -Material #81
   -Material #80
4. The following maps are only supported by 3ds Max; they will not be recognized by other applications. To learn how to convert them so they will be compatible with other applications, see the Render Map Dialog topic in the 3ds Max documentation.
   -Map #3
   -Map #351
   -Map #353
   -Map #204
5. The plug-in has detected modifiers listed above Skin (or Physique) in the Modifier list and must disable them.
   The following nodes are affected:
   -Mammoth-skinwrap

Especially 1. and 3. confuse me. How can I adress these issues?
Appreciate your help and anwers!

I use Autodesk 3ds max 2019 on a 64-bit Windows 10 machine.

Hi @Anonymous 

Is this model animated? If not, you can probably ignore 1 and 2.

For #3, this basically means that the materials that the model has been authored with are not guaranteed to be compatible when imported somewhere else, or in some cases can't even be written properly into the FBX file. There are probably some tutorials out there that can best explain how to get materials from 3ds Max into Unity better than I can explain, but I hope that this gets you pointed in the right direction.

Hey @brentscannell,

thank you for your reply. I was gone for the weekend so excuse my late reply.

The model has one walking/running animation attached to it. 3ds max itself can run this animation without any problems. And your hint for #3 helps me out a lot. I'll look into some tutorials.

Hi,

For the 1rst error, I made a tutorial about it last month, explaining how you can fix it,

What it means and in what scenarios it can occur.
