From: Mikko Rasa Date: Wed, 15 May 2019 21:42:03 +0000 (+0300) Subject: Redesign file writing in the Blender exporter X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=6ee541f;p=libs%2Fgl.git Redesign file writing in the Blender exporter Instead of writing statements directly to the file as string fragments, construct an in-memory representation of the exported data first. This allows it to be manipulated and combined easier. --- diff --git a/blender/io_mspgl/__init__.py b/blender/io_mspgl/__init__.py index 724d625b..30dc6406 100644 --- a/blender/io_mspgl/__init__.py +++ b/blender/io_mspgl/__init__.py @@ -7,7 +7,7 @@ bl_info = { if "bpy" in locals(): import imp -
