I am now doing test renders to go on Turbo Squid when ThinkingParticles 2 is released. I am learning so much that I do not mind working o with the tool. The only problem is that I see myself getting obsessed with it. I mean you can do whatever you want with the tool it is not limited by presets/defaults or key frames. It does require more steps, better planning and a little more time but it is worth the control and lack of limitations.
