Me: Eric Keller

Hi and welcome to my Blog. This is a hastily compiled record of my digital art and computer graphics experiments. I am a freelance CG artist living and working in Hollywood CA. I have written several books on Maya and ZBrush. Below my blog you'll find links to the books and tutorials I have authored and co-authored. I also occasionally teach at the Gnomon School of Visual Effects in Hollywood.I named my blog "Bloopatone" in honor of my first dog "Blue". She passed away a few years ago and I still miss her even though she was very grouchy and liked to bite me!

I'm proud to be an instructor at The Gnomon School of Visual Effects in Hollywood. Take a look at the work of our students and instructors on the Gnomon School Blog and the Gnomon Workshop Blog

Here is a link to my Demo Reel:

Bad Robot!

Started working at Bad Robot in January as a visual effects artist. My first month has been amazing! sorry to leave scientific visualization for a while but excited to be working with incredible artists and for one of my favorite directors (JJ Abrams.... duh!) Lots of cool stuff in the works but nothing I can talk about, at least not yet!

Octane for Maya Video Lectiure at the Gnomon Workshop

The Gnomon Workshop has release my lecture on using the Octane Render Plug in for Maya 2016. This is my fifth video series for Gnomon!! Such an honor considering I learned CG from watching Gnomon videos (on VHS tape no less!) way back in the late 90s. Check out the preview:

New Maya Tutorial on Maya fluids and Coral Nematocysts has published my latest video tutorial on Maya fluids as part of a series that covers Maya fluid dynamics. Evan Ingersoll and Rachel Davidowitz (two of my esteemed colleagues) authored the sections on nParticles and Bifrost while I discuss Maya fluid containers and cool fluid emission techniques. As an example I use an coral nematocyst animation that demonstrates the firing mechanisms found in the tentacles of coral polyps. Maya fluids are used to illustrate the venom as it is injected into the coral's prey. Check out the trailer on

Mecxican Honey Wasp (Brachygastra mellifica) model rendered in Octane for Maya.

Some renders of a ZBrush model I created. This was done for a tutorial in Issue 88 of 3D Artist magazine. This is a model of the Mexican honey wasp - yes a wasp that makes honey!! - many thanks to Alex Wild who sent me a couple specimens. I was able to examine the model closely using my microscope, tried to make it as accurate as possible. Check out Alex's article on his twitter feed :

Here are a few screen grabs from Nuke and Maya:
