Fluid Simulation; BR vs. Cycles (issue?)

Hey

I have been checking out fluid simulation and I have a few questions...

Using 2.72

  1. Am I right in thinking that the fluid simulation can only be baked if Blender is set to Blender Render? I can not get it to bake properly (at all) if I am in Cycles. This is not really a big problem if this is the case, but I just wanted to know if I am getting a bug...

  2. With an 'Obstacle', in order to get fluid to enter into the object, and not just bounce off the top, I have to have Volume Initialization set to 'Shell', rather than 'Volume'. Is this right?

Well, thanks a lot.

Also using 2.72 baking works fine with blender set to Cycles.

Yes you would have to set you obstacle to shell.

Baking a fluid simulation has nothing to do with the render engine (you may be confusing/ mixing this up with texture baking where the render engine chosen actually matters). I tested it out just in case it was a (really) weird bug, but it works as expected even with Cycles selected.

When it comes to obstacles, there is no way to make an obstacle's surface permeable (if that's what you want to do). Both 'volume' and 'shell' achieve the same thing in a different way. Here's the doc about fluid obstacles: http://wiki.blender.org/index.php/Doc:2.6/Manual/Physics/Fluid/Obstacle
