Mastering Blender 2nd Ed, just in time for Christmas

Posted in Uncategorized on December 11, 2012 by electrictownmovie

My own copy hasn’t arrived yet, but over on Oscar Baechler’s blog the news is that the book is officially out, just in time to reach your favorite would-be Blender expert in time for Christmas. Big thanks to Oscar for tech editing the book. He did a great job catching a lot of little inconsistencies that cropped up as we tried to keep a step ahead of the fast pace of Blender development! Documenting a moving target like Blender is always a challenge, and so a good technical editor is especially important. As the maven of the Pacific Northwest Blender scene, Oscar’s always on top of recent Blender developments, so he was a great choice to handle TE duties.

Thanks also again to Jonathan Ball from the unparalleled Poked Studio for the awesome cover art.

But where can I get this book, you say? The same place you get every other book, of course. Over at Amazon it’s actually been in stock for a couple of weeks already. For what it’s worth, the reviews on the book’s Amazon page are all for the previous edition. This edition has been updated and significantly expanded with material originally from Bounce, Tumble, and Splash: Simulating the Physical World with Blender, which is now officially obsolete.

In case you missed it, here’s a Table of Contents list I posted a while back for Mastering Blender 2nd Ed.

 

 

 

How well do you know the Image Sequence node?

Posted in Uncategorized on December 4, 2012 by electrictownmovie

Maybe I’m a bit slow, but it’s taken me a bit of figuring to get the hang of how frame sequences work in the Image Sequence node of the compositor, and I’m pretty sure I’m not the only one.

In any case, I finally decided that what I really needed was a sequence of frames with visible frame numbers that I could play around with, and that helped a lot. If anybody is interested in testing their skills with this, you can download a simple little exercise I put together here.

compblog2The tricky part for me was to figure out what, exactly, the fields “Frames”, “Start Frame” and “Offset” refer to. What do you think? Is this ridiculously obvious, or did it take you a few tries to get the right values in those fields? Do you see more than one way to get the solution?

Once you know how these fields work, it’s pretty simple, and I admit I’m not sure offhand how I’d go about making the interface more intuitive. (Although I would definitely prefer that the node were able to suck up multiple frames automatically, as when importing strips into the sequence editor.) There does seem to be some redundant functionality, but maybe that serves a purpose I haven’t come across yet. Anyway, I found playing around with this sequence to be helpful.

If you want to generate  similar sequences with other frame numbers, here’s the .blend file I used to make them. It’s simple, but maybe it will save somebody a few minutes.
