Dear bloodsong, the tree roots are normal Sonneratia from e-on - retextured with a photo texture. These purple things came with the sphere and the vomumetric thin smoke which touch the leaves of the trees. Made the smoke a bit additive glowing - so actually they are a mistake LOL - but I didn't correct it after previewing because the effect was quite nice. ;-) Bernie

Keep cool and fight for the right of others
to have a different opinion than you have!
