In this small tutorial we will create a smoke simulation with pre-roll, that is a cache on the negative frames in order to run the simulation for a specified number of frames prior to the beginning of the actual animation. Because of that the smoke/fire will be already initiated when the animation starts.
I’ve found those questions online and decided to write a tutorial about it, so if you are interested about the original istructions you can find them here:
Blender is a great tool but sometimes it will disappoint us, not because it lacks some functionality, but because for some features there is a functionIsThereButWorksOnlyAfterBlackMagicActivation feeling…
I’ve worked with simulations in the cloth, fluid and rigid body field and the ongoing revision of the physic system is a really great and challenging task for the Blender foundation (did you said tornado in project gooseberry?)
Well, my new kryptonite was is the smoke simulation and its parameters.
In order to do a bake of the smoke domain with a pre-roll of 100 frames(that is sufficient for my purpose, change it for your own task) you have to follow those few simple steps:
Let me know if you encounter any issue!
This guide is tested with Blender 2.71-2.74
Everything started back in june 2014, the summer is ending (here in Italy), everyone is going back to work and a bunch of lab monkeys from the copyright infringement division of the FOX network decided to scan the whole web looking for illegal acts of redistribution and diffusion of their productions.
Long story short, the FOX, through a direct request to Google asked the de-indexing of thousand of web pages, including my last article: Add all selected bones to a new Keying Set from the Google Search archives.
Check this link for the list of every removed content
My head boomed WTF when I’ve discovered it a few months later looking at a comment (thankyou!!!) into the incriminated article!
For those of you who have lived on a rock in the sea, inserted in turn in a closet, and closed with the key in the stomach of a sperm whale, the DMCA (digital millennium copyright act) is an U.S law that assure the right to remove everything from the Google search (and other web engines) by asking to Google itself via a formal copyright infringement request.
[This is obviously the best part]
My article is about “Add all selected bones to a new Keying Set”: a python script that allows to create automatically a keying set of the selected bones by pressing one button.
So the FOX network looked for removing everything illegal that involved their show “Bones” (!!!). This happened bypassing the authors of any page and without questioning themselves if the world should or not talk into blogs or website about an anatomic part that everyone has: The skeleton…
The steps to follow in order to restore a content are into the Google web search:
[If you know which webpages are involved you can skip to step number 5, in order to discover if there is any removed content that involves your website just continue with step 1]
Wait Google for the rest
Never talk about anything on the internet! even your body could generate a copyright infringement! just don’t do it!
I’ve made this demo reel to show 2013 cultural heritage projects of Cineca, the Italian interuniversity consortium where I work.
The modeling, rendering, compositing and montage was made with Blender 2.69 and cycles
I’ve got one of the first copy as a preview of this new book, the Blender 2.6 Cycles: Materials and Textures Cookbook, by Enrico Valenza (http://www.enricovalenza.com/). It is brillian 3D Artist, illustrator and Art Director, and also known for being the Lead Artist in the Big Buck Bunny production and in other projects in which I was also involved.
Now It’s very hot here in Italy and we are preparing for summer holidays… so I’ll do only a short review to explain why this is a valid and valuable book and why every cycles beginner and also expert user should have it.
