The Forest Pro Tools - export to Unity

<< < (2/3) > >>

MI3393:
Some Feedback.

I exported using Forest Tools, and imported to Unity3d

The position and rotation are not correct. It looks like it has inverted the tree models. And the rotation of the forest object is out about 180 degrees (mirrored).

I also got a few errors immediately after importing the forest object and FBX file.

I grabbed the last set of errors when updating a texture :


--- Code: ---Identifier uniqueness violation: 'Name:Forest_Pro/fp1/Forest_Pro/fp1/Forest002/Tree_50(Clone)/MeshFilter, Type:MeshFilter'. Multiple Objects with the same name/type are generated by this Importer. There is no guarantee that subsequent imports of this asset will properly re-link to these targets.
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)
--- End code ---

I will continue with this on Monday. I will go through the import process again, and document each step with screenshots and any errors I encounter. Is there anything you would like me to note ?

Morne:
I've also experienced the odd tree not having the correct rotation.

The error you're seeing I think you can safely ignore. I get that a lot with exporting archviz type scenes from max to fbx, then unity.

Which Unity verion are you using by the way and what render pipeline?

Also, you can find a newer version of the plugin here: https://www.itoosoft.com/download/UnityExporter

MI3393:
Thanks for the feedback, that is a later version of the Unity plugin.

I will install the unity plugin and try again.

MI3393:
UPDATE

I installed the latest Unity Package (101).

I don't receive any of the previous errors when importing a forest object and FBX.

But the geometry is still imported with each individual tree being inverted (180 degrees), and the forest object itself (grouped trees) being 180 degrees rotated about Unity's Y axis. I have attached an image showing the results.

Rotating the Forest object 180 degrees is no real issue. But I cannot manually add 180 degrees to each individual tree quickly .... ( I probably could write a script to iterate over all the sub-objects and rotate them).

I am using 3ds Max 2018 (for Mental Ray legacy) but also have access to 3ds max 2021. Using Unity 2020.1.4f1 and HDRP high definition render pipeline.

The forest I am trying to export uses 3 very simple "tree" objects. Created using lathe.

Paul Roberts:
Thanks for the feedback Dave,

Have you tried resetting the XForm of the source geometry before exporting to Unity? It might be related to this.

Cheers,
Paul.
