This morning I started working on some sketches for some coral fungus types (about 12), and a few additions to the club and cap mushrooms (about 10). I've also started working on some saprophytic plants in red and yellow (about 3). Many of these will be smaller than man-sized, so they're just normal decorations to spruce up the caves.
I've put no work into the crystals at this time, but I did start working on an element splitter with a retexturizer built in. It should let me convert those crystal columns to individual elements, and then apply this new crystal texture to them programmatically. It is just too much work to do all 24 shapes by hand with my limited schedule. With it I should be able to copy the effect on the type b crystal, and share the texture and color setup.
Cave BACON! I had forgot to make cave bacon while doing my cave formations. I got a bunch of images for it, but never worked on the model. In addition to some soda straws and some spiny crystal growths, a lot of this stuff will be done with billboards, or like the bats, almost billboards.
As mentioned before, I'm going to just flip the stalagmites and paint the bottom black. I'll then give them a basic height offset of 10m, but the builder can specify a better height in the toolset.
As soon as I get that stuff done, I'll start packing biscuits of smaller cave formation clusters. They'll be like the globes of crystals in the water tiles, and also like the globes of mushroom clusters. That is that they'll be a basic globe with simple repeating texture, but with a few of the visuals created in 3D to randomize the view at different angles. For an idea of what I mean, check out my mushrooms pack #1. You'll see that the blue, brown, and gray mushroom globes all have a squiggly row of 3D mushrooms coming out the top, in the same colors as the globe.
