Difficult to see people behind large trees. Green circle selection indicator is not visible.

I am enjoying Sulis however I keep losing sight of characters when they go behind large trees.

I see that when a character goes behind a tree their sprite is faded, but it is very difficult to see them. I think it should be the tree sprite that is faded instead of the character sprite.

Also the green circle that appears beneath characters when they are selected disappears when behind a tree. I believe it should still be visible.

If I am understanding you correctly, I agree with your overall assessment. This is unfortunately really difficult to do the way Sulis's rendering is currently structured. An easy thing to do is decrease the transparency on the characters that are being drawn on top of the terrain layers. But, this has downsides as it pretty quickly makes it look like the characters are floating on top of the trees.

The green selection circle is basically impossible to render both on top of the terrain (trees) and still behind actors at present.

A comprehensive approach to fixing these issues would probably involve setting up a rendering pass making use of the stencil buffer.
