And I updated it already!

I can't leave anything alone.  I have updated my tutorial ALREADY!  The download is available on this page (look for the "Download PDF" link at the bottom).

After chortling heartlessly at many more people's mistakes with Speculars (two mistakes of which I confess I've also made), I decided on a swift rewrite of that entire chapter.

If you believe any of these (and some are more 'wrong' than others), then I urge you to at least read that section of the guide because you're getting it either slightly or massively wrong!  It's short, and will save you being ridiculed at parties should speculars come into conversation (speculars being typical party conversation)...

• The specular's alpha should be 50% grey
• A specular is rarely needed; the image is usually empty
  
• Speculars should use EA's 'empty specular' image
  
• Speculars are nothing more than a contrasted multiplier
• Speculars don't need an alpha unless the alpha is to be used
• Speculars can only be black and white or greyscale
  
• The Workshop loses the Specular alpha
  

I've completely rewritten the Sepcular section based on some of the things I've been hearing because there are a lot of us out here who have made these same assumptions.  I've used better pictures to show how it works, and removed all that nonsensical repetition too. I've added a new myth-buster section to explain what's wrong with some of the aforementioned assumptions, and I've also updated a few other sections with additional tips too.

I apologise if you wasted a stupid amount of green ink by printing the previous version.  I have no plans on any further updates.
