 - **Step 3:** Press the button that says "Apply [skin name]"
 - **Step 4:** You're done! If the user interface appears to not update, be sure to **check rendered view** (shift+z). Also note the default behavior is to make a *new* material. This way, if you had other characters with the same skin that you don't want changed, those are left alone. You can turn this off in the redo last menu or via F6.
+  - There are some redo-last options to control how skin swapping is done, changing any of these settings will undo and redo the skin swap with the newly applied setting.

 - **Collection effects:** Simply add new effects to new blend files in the MCprep resources folder: MCprep_resources/effects/collection. The animations are assumed to start at frame one, and offset accordingly when spawned in a scene later.
 - **Image sequence effects:** These are read from the active resource pack's effects folder. Simply place your image sequence of files there and it should load in automatically. Alternatively, point the active resource pack to the parent of another effects resource pack folder (the active resource pack must be pointing to the top level of the resource pack still in order to recognize the folder for image sequence spawning)

 #### Cycles Optimizer Node Settings

+*NOTE: the Cycles Optimizer is deprecated and will be removed in MCprep 3.6*

 The Cycles optimizer also comes with it some special node names to control how it interprets certain nodes. They are the following:
 - `MCPREP_HOMOGENOUS_VOLUME`: if applied to a Volume Scatter, Volume Absorption, or Principled Volume node, it is treated as a homogeneous volume 
 - `MCPREP_NOT_HOMOGENOUS_VOLUME`: if applied to a Volume Scatter, Volume Absorption, or Principled Volume node, it is not treated as a homogeneous volume
