FBX Importer: AI_CONFIG_IMPORT_FBX_PRESERVE_PIVOTS=false not always working correctly

[RichardTea]

In at least some models, setting this flag results in some meshes having very incorrect position/rotation.
Eg:

AI_CONFIG_IMPORT_FBX_PRESERVE_PIVOTS=true:

AI_CONFIG_IMPORT_FBX_PRESERVE_PIVOTS=false:

I'll try to create a smaller example model, this one is quite large and isn't public.

I see this too, but I don't have an exact model to check.

I had same problem, test this model: https://www.syncs.online/W7z/BMW_i8_Coupe_2015_3D_Model.zip

AI_CONFIG_IMPORT_FBX_PRESERVE_PIVOTS=true:

AI_CONFIG_IMPORT_FBX_PRESERVE_PIVOTS=false:

+1, seems to have been an issue for a while (over a year)

[RevoluPowered]

We are working on fixing this as we really need this in Godot.

@RevoluPowered Just wanted to see how you were getting on with your fix for this issue?

[zbendefy]

@al2950 : it seems they went on by implementing a custom FBX importer making this issue irrelevant to them (godotengine/godot#39418)

Are there any news/info on this issue?

If you want notes on the math, I’ll see if @RevoluPowered or others have spare time and effort to send docs.
