I select geometry and click FLIP Fluid from Object tool, then the perspl interface darkening and I can't see anything. But corresponding node can create. Why? I operated same way by SPH Fluid from Object tool, it is noraml.

I use Houdini 11.0.458 edition.

No one can answer my question? :cry:

What OS are you using? Drivers version? Video card?

I was getting this on my Mac Pro, 8800GT, but it went away after I updated to the latest version of Snow Leopard, which updated the graphics drivers as well.

OS: Win7 Pro 64Bit
Video: ATI Mobility FireGL V5700
Drive: 8.641.1.1000
