Vertex animation textures, beanbags and boneless animations.
Added 2020-10-12 17:55:44 +0000 UTCSkeletal animations are amazing but they can't be expected to do everything well. In my latest video I demonstrate the technique of using vertex animation textures to get a tricky physics-based animation out of Blender and into Godot in a 60-fps-friendly way.
Thanks to all my Patrons for contributing to the creation of this and the many videos to come!
Martin.
As always, the project files for this video will be uploaded shortly as a Patron-only post.

also extended this function so the orientation, scale and location stays consistent in the copied object: def new_object_from_frame(obj, f): """ Create a new mesh from the evaluated version of obj at frame f. """ context = bpy.context scene = context.scene scene.frame_set(f) # the correct way to set a frame and update depsgraph dg = context.view_layer.depsgraph # need depsgraph to access evaluated mesh attributes eval_obj = obj.evaluated_get(dg) duplicate = bpy.data.objects.new('frame_0', bpy.data.meshes.new_from_object(eval_obj)) # Copy transformation data (location, scale) from eval_obj to duplicate duplicate.location = eval_obj.location duplicate.scale = eval_obj.scale # Check rotation mode and copy rotation data accordingly if eval_obj.rotation_mode == 'QUATERNION': duplicate.rotation_mode = 'QUATERNION' duplicate.rotation_quaternion = eval_obj.rotation_quaternion else: duplicate.rotation_euler = eval_obj.rotation_euler return duplicate

I did have to change the blender script somewhat to get it to work with blender 3.x and spark though: MD_MorphTexture.py This makes sure that the proper object is exported (didn't work OOTB IDK maybe something changed in blender) and also that the object is exported as FBX, because the GLTF/GLB export (for some blender reason) changed the UVMap name which made it not work in Spark. enjoy. def export_mesh(obj, output_dir, name): if obj.name not in bpy.context.view_layer.objects: bpy.context.view_layer.active_layer_collection.collection.objects.link(obj) bpy.ops.object.select_all(action='DESELECT') obj.select_set(True) bpy.context.view_layer.objects.active = obj output_dir = output_dir + name + "_" + "mesh.fbx" bpy.ops.export_scene.fbx(filepath=output_dir, use_selection=True)
