I found that viewing parameters in MC4D that are optimal for me are different for different puzzles and for different stages of solving.
For 3^4 I use some medium sticker size and medium-to-small faces. Sometimes I find that it’s better to use smaller stickers on the first stage (search of "red" 2C stickers), but usually I forget about it (or have no time).
For 5^4 I’ve used three different settings. On the first two stages (solving of the first center and of "central" 4x1x1x1 columns) there were small stickers and small-to-medium faces - for better view of inside stickers. On the next stage stickers were larger (with 20% gap), but faces were small enough so they haven’t hide each other. On the last stage (after reduction to 5^3) I’ve set sticker and face separation to almost zero - so that the puzzle looked like more familiar 3D cube.
Puzzles with small face number (simplex and {3}x{3}) require the minimal possible "Eye W Scale" parameter - and it wasn’t enough: external faces of puzzle appeared almost flat. And for these puzzles I heavily use free 4D navigation (right-button sliding). Sticker and face sizes are medium.
Prop files for these cases are in file.
