Sorry but carrara doesn't cause bloodpresher issues for me. Yes it has it's issues and faults but I know it well enough to figure a way around them. Now that I have the work flow figured out for doing studio; optitex, dynamic clothing animations to be staged in carrara, I did 8 runthoughs yesterday. 

The best I have ever done with Blenders is get so worked up I thought my eyes were about to pop out. The only other time I have gotten that worked up was from playing FFXIII on the PS1. lol
