Why Does Maya Batch Render Too Dark?

Utah Teapot

Lighting your scene using Autodesk Maya can be a tricky process. You get your lights to look just the way you want them to, and when you render out a single frame, everything looks fine.

But then, when you come to do a Batch Render of your final frames, Maya gives you a very different result - the images look much darker. Which is not what you wanted at all.

So why does Maya do this - and what is the solution?

Mental Ray Is Back - And It's Free!

Mental Ray is Back! NVIDIA, makers of the classic ray tracer - it used to come bundled free with Autodesk Maya - have now released a version of their software which is free for student use.  This is great news for animation students, because Mental Ray has a number of advtantages over its successor Arnold.  In particular, you can achieve some very quick and attractive lighting setups in Mental ray using Physical Sun & Sky, the closest thing Maya has to a "Make It Look Cool" button.  So, how can our students get a free copy of Mental Ray?

Make Your Own RenderFarm With Backburner

Rendering, as my old tutor at Escape Studios used to say, "is where everything starts to go wrong". Here at Bucks we expect our students to present finished, polished work for their assessed submissions, properly lit, textured and rendered out. But this poses problems - render times can be long and, as deadlines loom, any technical failure can be fatal to a timely submission.  So, in the absence of a high-end render farm, how do students render their work on time? The answer is Backburner - the poor man's render farm.

Free Textures from Pixar!

Pixar have recently released a number of free repeating textures from their archives - for use in 3D animation. The archive was first created in 1993, and is now free for use by the rest of us - for the first time ever.  Included in the free release are bricks, metals, fabrics, skins, ground surfaces, and tons of other stuff. All of them are designed to repeat seamlessly with no nasty visible joins.

Renderman, Free At Last!

Pixar's Renderman, one of the leading industry software packages for rendering high quality animation images has at last been released free to students on a non-commercial basis.  Pixar's RenderMan is used throughout the CGI industry for the creation of stunning visual effects, and is highly recommended for student use.

Student Showcase - What Have Our Students at Bucks Done?

One of the most important things to look at when choosing an animation course is to check out what other students on the course have already done. If they have done excellent work, the chances are that you will too. Why? Because few students produce great work by themselves.  Most of us require motivation, inspiration, and the discipline of a well structured curriculum to guide us through, and help us do the best work we are capable of.  We're proud of the work our students have done at Bucks. Check out some of their excellent work below.

How To Make a Batch Render of Your Frames in Maya, and Export a Movie File

How do you make a Batch Render of your frames in Maya?  Remember that computers will drive you crazy, and when it comes to technology, things rarely go to plan. Google is always your friend when it comes to troubleshooting technical problems. Someone out there will have the answer - if you can just ask the right question.  Below is a technical cheat sheet that should help you to create beautiful, final rendered images - and a movie file - without too many tears.

Aspect Ratios Explained

Standard aspect ratios: SD, HD and super HD

Aspect ratios are one of the more technical aspects of our business - confusing when you don't understand it, and on the face of it a bunch of random numbers.  It can all be pretty hard to fathom, with lots of geeky acronyms and odd terminology.  That said, a basic understanding of aspect ratios is necessary for all digital artists - it's how we configure our work for the screen. When you render your shot, and when you edit your work in Premiere or Final Cut, you will have to make choices as to what aspect ratio to select.  So, to take the pain away, here's a link to an excellent blog post - aimed at digital editors - to explain all these confusing terms and what they mean.  And below is a brief summary of how it all works.

Bringing the Digital World to Life

Modeling, texturing and lighting by Mike Swan

Here at Bucks we don't just tackle animation - we also train our students to be experts in a full range of digital skills. Students often ask "should I become a specialist - or a generalist? Which is best?". The answer of course - is both.
