Yes, the trick is that you need to click "Split by: Groups" when importing into Blender. I've noted this now in the documentation.
Also, new Version 7.07, fixing a minor bug (which will affect you, mine101). If you don't "export to individual blocks" you don't need to get this new version. The bug fixed: when stairs are put next to each other and "Export individual blocks" was chosen, the sides of the top part of the stair step were not exported.
I like to always include a picture, so here's the so-exciting screenshot from testing in Blender, showing these blocks that were moved are now whole again:
Added 1.15-pre3 bee nest, beehive, honey block, and honeycomb block.
Added 1.15 biome reader, so we don't crash. NOTE: I haven't figured out how the 1024 integer biome storage works yet.
Made nether portal have true geometry instead of a whole block.
Bug fix: redstone wires should not run down the sides of upside-down stair blocks that have redstone on top of them and connecting redstone a level below them. (Thanks to Quinlan W for reporting this bug).
Bug fix: when using MCC ToolChest PE, the order of stair Properties is reversed, which revealed a subtle bug in Mineways when translating upside-down stairs' data values; now fixed.
Interpret 1.15 biomes correctly. Technical details: The 1024 integer array is 64 levels of 4x4x4 voxels. In Mineways only the 4x4 biome values for levels 64-67 (level 16) are used, the rest are ignored for now.
Bug fix: redstone wires should not run down the sides of upper-half slabs that have redstone on top of them and connecting to redstone a level below them. (Thanks to Quinlan W again for reporting this bug).
