View Full Version : seriously need help!

04 April 2008, 10:50 AM
Hi, I'm now stuck at a problem which i am unable to solve. I had created a nurbs plane and apply an ocean shader on it. And also some emitters for my boat to create wakes and foams. I used 2 3DfluidTexture for both the wakes and foams respectively. And i have some nice effect that I want. However, something annoyed me. After rendering from far view, i realised that the whole ocean is filled with the wakes and foams i created for the boat.. This is due to the size of the fluidTexture as I only position it at where the boat travel... If i scale the fluidTexture to the same size of the nurbs plane, i will be able to solve the problem, however, my scene are incredibly big.. Hence i cannot afford to do that.
Anyone can help me with this problem? I seriously need a help there. Pls reply me asap as I have not much time left. Thanks!

Can you post a render and indicate the undesirable effect? Your ocean will still have turbulence and wake if those attributes are above zero on the shader.

sorry for the late reply...

Looks like your UVs are repeating, go to the rebuild option under Edit Nurbs and reset settings. Parameter Range needs to be 0 to 1.

after doing some research, i can guarantee that it is not the uv problem...
i have tried ur method, rebuilding it, i have tried using another nurbs plane, and tried even poly plane... all have this problem...
i guess is becos of my fluidTexture.. becos, it seem to repeat itself on the oceanShader...
if i resize it to as big as the plane, it will have only 1 wake and foam... however, if i rescale it to like for e.g. half the size of the plane, it will have 2 wake and foam...
understand??? seriously need some advice, why does this thing happen??
is becos of some attr which i set wrongly? or becos i connect wrong attr to the oceanShader??
outAlpha to foamOffset and outAlpha to waveheighOffset... any1, pls?
