Tutorials , tutorials that is the problem. I am looking for hours to find a answer to a simple question.

I am not sure I understand your question, but there are a ton of tutorials for Houdini out there. I will list a few below and hopefully you will find one covering your needs!

Im sure if you cant find the answer in a tutorial, post a question on this or http://forums.odforce.net/ [forums.odforce.net] forum somebody will be able to help

I'am sure that the best way to get a quick answer is post your questions in the forums. Houdini has a great responsive community and I've always found the replies you get are very helpful, not only to answer your questions but to understand more whats around it!

Tutorials gives you steps to achieve a particular setup but don't always get you informed about all the technicalities and why they proceeded that way!

Search the forum and if you can't find what you are looking for, post it !
