Purple blinking water + phantom reflection?

Troubleshooting graphics
1

see for yourself:





any idea? all 3 jme-tests are working fine

do you have the same up direction as the tests? and if not, do you set the tangent/binormal stuff correctly. also, do you have fog setup?

i don't know. just copy&pasted everything. the answer seems to be yes - if i just let the water reflect the skybox and terrain, everything is fine.

if i add everything, i get weird errors. yes, there is fog.

I have seen this error with the water before… there was a thread in the forums, but I don't know where.
