- +Many Blender tutorials exist on YouTube. However, they usually go +into painful detail about consfusing options that do not help beginners, +which are the audience of tutorials in the first place. To offset this +lack of Blender information, I created a course for when I was teaching +Blender. These free and public-licensed + +Tutorials are here (that is the Blender 2.5-2.7 directory--for 2.8, +click "Index" at the top).

+10 Blender units is 1 Minetest unit, so if your creature should be +1.6 meters tall (5 ft 3 in), then the model should be 16 Blender units +tall. +
visual_size specifies size for 2D sprites such as wielditem, in
+Minetest units (default 1 x 1 is 1 meter square).visual_size specifies scale for meshes. For
+example: The mummy from tsm_pyramids is about 2 Blender units (also same
+for b3view), the
+visual_size in Lua is 8, result is looks like it is the
+expected 1.6 Minetest units high. 1.6 is the expected result since the 2
+Blender units are divided by 10 resulting in .2--multiplied by
+visual_size 8 results in 1.6 Minetest units.
