Wow! You are right Dwight, I purchased the Cacti and Succulents Disk from the Maxon Store. These plants look terrific. 20 Pre-made Cacti representing completely accurate models of the plants we see most often here in Southern California and Arizona.
Look at this rendering, I added an Agave to the previous scene. I am going to find out if XFrog can create a realistic grass lawn also. This scene renders in just a minute and 30 seconds, but it really grinds down when it hits the grass section. My goal is to find a fast rendering (yet realistic) way to add grass into the renderings of homes. Perhaps XFrog will do the trick.
Check out the PDF manuals, there seems to be so much information about this product. I don't know why I didn't see it before.
Whew! end of plug
