problem solved, i've upgrade to ver 7.80, all done..
thx all
hmmm, unfortunately the problem hasn't truly resolved..
before ,, im trying to install ver 7.80 trial and I copied all project folder (main.cd included) from my project folder in my PC to my friend's notebook and publish it in WED, then i run main.exe there and the water shader works well..
I think the problem has resolved with compile my project with that version..
but actually the water shader can't work in other computer (with same platform, i have tried with 6 other computer with different platform and the same platform)..
lately, i know that trial version can't publish *.exe.. So, it means main.exe that i run in my friend's computer is generated (compiled) from my old version of 3dgs(7.05), right?
can anybody explain what exactly happened here? pls help me with the solution..
thx before..
