Hi to everyone,

I am currently trying to figure how terrainBlockMesher utility works, but I am having some problems with the Dict file. I have defined everything like is told in the tutorial and I have adapted the file to my case, but the same error appears with any modification.

Could somebody help me with this problem? I will appreciate it.

THE ERROR FILE:

PHP Code:
