Mode 7 horizon issues

[Breadcaster]

Hey everyone

Ive got some issues setting up mode 7 with Bennu. I set up a quick program and got everything set up with the right coordinates and height etc for the game Im making, but i cant get the horizon to work - no matter how much the value is changed, it wont seem to raise or lower? I dont know if Im doing anything wrong but nothing will work. I included the code below (its not very long) so you can see what I'm talking about...

Is this possibly to do with my version of bennu? is it broken in an old build?

Any help or ideas would be appriciated - thanks a lot! :)

Wooops. One year with no answers? What's happened?

Ok, just for the record, horizon variable on mode7 never worked. Not in Bennu, not in Fenix. It only worked on DIV and DIV2. It was one of the features that never was implemented.

it makes sense  :-\
