Blender 2.5 - Character Animation Cookbook Issues Found: Page 20 - Step 2 mentions to set Radius to 100. That seems much too high. Page 38 - Step 6 - For Step 6 the Copy Rotation contraint for the FK_arm bone is called Const in the gui, it will need to be renamed to match the name expected in the paragraph. Page 76 - Step 8 - Should probably read "Now enter in Pose Mode. Select the M_Eyelids.L bone, lock all its rotation values, and the X and Z for both location and scale, ......" Page 86 - Step 13 - The text that reads ", change the Expr Field to var" - change to ", change the Expr Field to var-1". Page 93 - Step 4 - All new shape keys in Blender 2.58x take their start shape from the Basis shape. To get Key 2 to have the shape of Mouth_cornerUP.L, click on Mouth_cornerUp.L and then click on the Down arrow button and select New Shape From Mix or in the toolshelf area make sure the option From Mix is selected. Page 95 - Step 5 - The file 004-Face-shapes.blend is probably the wrong file the correct file is 004-Face-drivers.blend. As that file contains both the shape keys and the bones referenced in the paragraph 004-Face-shapes.blend file does not. Page 96 - Step 9 - Should probably say repeat steps 7 and 8 and not 6 and 7. Page 120 - Step 3 - the text that reads "rename them to IK_Thigh.L and IK_LowerLeg." - should probably be "rename them to IK_Thigh.L and IK_LowerLeg.L" Page 120 - Step 4 - Must be in pose mode when carrying out this step. Page 159 - Step 7 - Mentions that 006-Props.blend has a complete example the file is called 006-Props-complete.blend. Page 165 - Step 1 - The file is named 006-Tracking.blend not 005-Tracking.blend Page 170 - Step 7 - Transparency value for this step should probably be set to 1 not 0. If the effect shown in the book is what is wanted. Page 171 - The paragraph that reads "The file 006-VideoReference.blend has..." - Should probably read "The file 006-VideoReference-complete.blend has...". Page 203 - The paragraph that starts "The following screenshot shows our adjusted poses, and the file 007-Symmetry.blend has ..." - the file should be called 007-Symmetry-complete.blend"
