Thanks for the upload. I just had a check at your pictures: it does look like there is some weird aliasing problem on the foreground layers, the base layer is fine.
I may have a go at it, but not right now. It would be difficult to give you a very straightforward procedure for this, however I can give you some tips from my experience at working on that process on previous scenes (the sewer scenes, namely):
- it may not be mandatory to follow all the cuts of the original layer arrangements. I would advise not to duplicate objects from the base layer on a foreground layer when it isn't necessary.
- for Blender: I'd recommend you put foreground objects on, say, Layer #13 (3rd layer of the right block). For instance, you isolate the main pipe, the table, the computer and the cables on that layer. Then, on the Scene tab of the Properties panel, on the "Scene" side (left), you select all the layers which are going to be involved in the render (ie layers 2-10, 11 and 13) but on the "Layer" side (right) you only select Layer #13. If you render that, it should only give you the pipe, the table, computer and cables with minimal aliasing. Then, you can place these items back on one of the background layer, and select another group of objects to be rendered on Layer #13 (for instance, the chest of drawers, with the medkit and the brown flask), and render these ones, and so forth. Once you have good antialiased renders of these items, you can recombine them with Photoshop later, as needed (you'll need to recut layers via photoshop anyway, for instance when you need to put a chunk of the pipe on the third layer). Note: I don't know if you went through this process precisely already - it's a bit of a guesswork on my part. In any case, I did manage to have neatly antialiased renders on my end when it came to render distinct separate objects.
Now, with all these considerations: it turns out that the fields still produce some aliasing in game. However, I am not sure whether it is actual aliasing, or an artifact due to the fact that there are problems to display images which are at a resolution which is not an integer multiplier of the original (since HD is actually 4.5 times the original - my renders being 5 times).
I hope that helps. I don't know if you'd like the layers I made for the sewer scenes on the repo, to serve as a reference.
I can smell those daisies now!
I thought I had based my flowers on lillies
