Iridium has not lost any love in development. Some test concepts here and a quick sample of some of the assets. The cracked desert textures still needs refining and will be transparent layers on top of the sand texture.
I have a few tricks up my sleeve to achieve the seamless texture but its going to take some time :)
Iridium out of all projects i am involved in certainly will be the most time consuming and we hope to one day have this posted on a kickstarter or similar site, early days.
