- Yeah, the reflected light off the ground looks pretty good. It's not so obvious in some of the other graphics because the terrain tile is there. The light effect takes a bit of extra work on top of making the model itself, so I was holding off on making the graphics with the reflected lighting till the general theme and a good deal of design work was done.
- The difference between the last two CHAPS is very subtle. I basically went in and tweaked the last one to add a bit of definition to the lighting/shadows. It's very subtle and was probably unnecessary to post both, except that I was also bouncing things off Leeor at the time.
- I am struggling a bit on the color scheme of the warehouse. I think the frame on the structure adds a nice element, but the colors need to be balanced enough to be noticeable, but not distracting.
- I'm not sure how much webbing/grids/frame there is to simplify off the structures. The command center and the warehouse are really the only two that have additional framework. I suppose the tubes do as well, but they are pretty bland when just one solid tube. The agridome necessitates a frame since it's holding glass. Quite frankly, the command center doesn't look like much of anything when it's just a dome. I could remove the frame off the warehouse and give it more rolled curvature.
Part of the issue is that the graphics are so small, there needs to be extremely distinct details to give it some feel of depth. The command center seemed to be a great candidate for additional structure, since it needs to be extremely sturdy. Of note, I also just posted a couple tokamak designs. The first includes some grid structure and (in my opinion) doesn't look great. So in that case, I agree with your comment that it's not necessary. (And including it on every building would certainly be overkill.)
I've uploaded a warehouse without the structure, but with a ribbed design. Leeor has started a new thread for it here:
