Mesh Normals can't be Calculated

[SigmaEOD]

Having an issue while exporting my model to P3D

I've installed the latest 4.1 version of blender and the latest release of A3 Blender Tools

Here is my error log:

Python: Traceback (most recent call last): File "C:\Users\alexa\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\ArmaToolbox\..\ArmaToolbox\MDLexporter.py", line 944, in execute #try: File "C:\Users\alexa\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\ArmaToolbox\..\ArmaToolbox\MDLexporter.py", line 713, in exportMDL if len(objects) == 0: File "C:\Users\alexa\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\ArmaToolbox\..\ArmaToolbox\MDLexporter.py", line 811, in exportObjectListAsMDL newTmpObj.select_set(True) File "C:\Users\alexa\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\ArmaToolbox\..\ArmaToolbox\MDLexporter.py", line 677, in exportLodLevelWithModifiers possiblyRenumberComponents(tmpObj) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\alexa\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\ArmaToolbox\..\ArmaToolbox\MDLexporter.py", line 499, in export_lod #normalOffsetInFile = filePtr.tell(); ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\alexa\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\ArmaToolbox\..\ArmaToolbox\MDLexporter.py", line 153, in writeNormals if (4,1,0) > bpy.app.version: ^^^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'Mesh' object has no attribute 'calc_normals_split'

Try to delete the addon and re-install it. The later toolbox does not call calc_normal_split anymore if the version is greater than 4.0.
