Hi and I'm sorry to hear to here you are having difficulties with Songbird ReMix. Let's go through the issues...
The reason for you not seeing the fluffy feathers is that you have to activate them through morphs. The majority of the Fluff feathers are found in the Hip and Neck section in "Action Morphs".
As for the Raven texture, you found an error in the set (I thought those references were corrected years ago). I think the only one which is the American Robin.
Either go into the material editor and change the Iris material diffuse texture from "Raven.jpg" to "amrobin_m.jpg" or download the attached file (at the bottom of this post).
For the small squares on the wings, I assume you are doing Iray renders. Physical renderers like Iray and Superfly have trouble with the super thin feathers. When the feathers bend, there isn't enough geometry to compensate for a smooth bend, hence the backsides of the feathers interfere with the front sides. If you try rendering the model in 3Delight (or Firefly in Poser), you'll see there isn't an issue, because they are much more forgiving renderers.
...but we'll get you an Iray render and there is an pretty easy solution to this. With the model loaded, go to the Scene Tab and click the little box...
Go to "Edit" --> "Geometry" --> "Convert to SubD". Now, your model will be in SubD and ready for subdividing. Go to the "Parameters" tab and in the model, select "General" --> "Mesh Resolution". Turn the "Render SubD Level" to "3" (that will take care of the little blocks). I like to change "Edge Interpolation" to "Soft Corners" as well.
If ever you get an exploding model (geometry going crazy) in SubD, switching the Algorithm from "Catmark" to "Bilinear" usually solves that issue.
All of these issues will be solved by years' end when I complete the massive 1,000+ bird update I'm currently working on. The update will include having support for all 4 renderers (Iray, Superfly, 3Delight and Firefly), All morphs and control in the Body section of the model for easier access, translucency added to the feathers and much, much more. Updates, as always, are free to my customers.
Since you have the Songbird ReMix base set, you might want to get all the freebies I have for it on
my website (look under downloads).
Hope that helps
