'java.lang.UnsupportedOperationException' because 'com.google.common.collect.ImmutableMap.put'
you can't put things in a ImmutableMap, you will need to get all objects from the Map and then create a new Map
Edit: you can't use a for-each loop on a ImmutableMap (Minecraft.getInstance().getEntityRenderDispatcher().getSkinMap() will return a ImmutableMap)
you need to create to create a new HashMap and do then the for-each loop (you can use Maps.newHashMap and put Minecraft.getInstance().getEntityRenderDispatcher().getSkinMap() as parameter)
