Hi there!
After a few days of little frustration with TG2 (my actual work doesn't show the result I want) I browsed my Harddisk to delete old files (spring-cleaning in autumn).
There I found some so called "bump map files" of an old Paint Shop Pro version. All black and white for using as masks ... hmmm .... black and white ? Heightfields ..... ? Well ... I saved them as "TGA", loaded them in TG2 and made some testrender.
Camera position exactly above the terrain and 90 degrees downwards
The result was "something completely different" :D
Attached are the files:
1. the loaded heightfield (TGA)
2. the "green labyrinth"
3. the "ornament" (inverted heightfield), looks like an ornament of an old cathedral
Great idea!
It would be a challenge to produce ornaments like this by procedures....
