  <p>I have found that we need to change the composition settings. </p>
  
  <p><strong>If you want access to the blending modes, ensure your composition is using the Classic 3D rendered. This can be found by going to your composition settings, click on Advanced tab, then select it from the Renderer drop down list.</strong></p>

Comments.Text: My guess is that layers only have blending modes if they have alpha channels associated with them.  If your layer has no alpha channel, what would be the meaning of the blending mode?

Comments.Text: Blending modes can be applied without needing alpha e.g. `lighten` is mathematically `A > B ? A : B` where A is value of the R/G/B plane in top layer, and B bottom layer. And in any case, I believe AE assigns a default alpha of fully opaque if the media doesn't have one.

Comments.Text: If they were precomps (like layer 6) and collapse transforms is on (the sun icon) you won't be able to set a blending mode. Shouldn't happen for layer 7  and 8 though.
