You bloody ^^ didnt your mum always say you to check uniform locations first? :D

Actually that's the second one, first one is "not accept candies from strangers" :p

However, I was referring to this Debug Output. You can find an example here . It is muuuuch more human readable and helpful.

Ps: don't use spare uniform, use UBOs (or SSBOs)
Pps: use explicit locations if you can
