Learning RF4: one small step, more questions!

I've been learning MAYA dynamic for a while and so far I've found it although powerful and handy, having a lot issues when it comes to simulating/manipulating fluid and particle events (i.e...collision detection). So learning RealFlow4 is my new thing in order to make my already falling behind thesis happen.

It's great to find out that RF4 can generate splash when objects colliding with the RealWave surface, unlike maya softbody has really limited practices. However the performance of doing it is really not rendering friendly. Besides, I haven't tried out if this can work with dynamic instance. It's such a drawback that MAYA doesn't allow dynamic instance behave like rigid body....it's SUCH an obvious need AUTODESK!!!

Anyway....technical questions are popping out like hell...
  • How to make dynamic instances behave like rigid body?
  • How to create splash when the object ( likewise, dynamic instances) hit the ocean surface?
  • How to rig a soft-body creature...in my case, an octopus?
  • How to create underwater kinda look?
  • How to rig a whale?( this one I think I already found some potential solution...need to test it though)
BTW...I heard MAYA2009 improved the particle system (nParticle) and fluid dynamic a lot...
hope that will help me eventually~

MentalRay Gets Bitchy On Transparency Map

http://www.3dbuzz.com/vbforum/showthread.php?t=158984 If this transparancy map is a file texture and you are using maya 2008 then you will need to check the "alpha is luminance" flag in the file texture attributes. This is an assumed default for the software renderer, but not for mentalray. this is a new setting turned off by default in maya 2008 hope this helps

OS: everybody has highs and lows OS: But like other ten millions, I am facing something different OS:Bipolar disorder is a real illness, like cancer or diabetes OS:The chemical imbalance in my brain makes my moods and energy shift OS: severely. OS: For people like me, life is a repeat cycle OS:Between Mania OS: and depression OS: medical treatment is key OS: However, finding the right one, is challenging OS: People talk behind us, saying that we are crazy. OS: We are not. we are just fighting a life-long battle that we been forced to fight OS: you may not understand OS: but you can be a friend So this is the storyboard I've been working on this weekend. Ideally it will be a piece that combines motion graphic and 3d visual effect. Sorry if some transitions in between is not very clear right now. It took me a long time trying to make it informative and making sense in a way. I also took the suggestion of Ethan from midterm presentation and tried to make the OS sounds more personal. ...
