Hey everyone,

This week’s video tutorial is about how to use the Image Control mechanisms in mental ray to control the “curves” of your final render.  By keeping track of your highlights and lowlights in the “mr photographic exposure control”, you’ll be able to have great looking renders and preserve the fidelity of your final image going into Photoshop.

I know this is old, but it’s still a great demo. I’ll keep my ear to the ground for any other developments.

Hey Everyone,

This week’s part 3 of the 3-part series on rendering HDR panoramic images in 3dsMax or Vue 6 Infinite, and then bringing them back into 3d Studio Max.  This week I’ll show you how to set up the lighting and background in order to make use of those HDRI files we created.  It’s easy as pie!

nVidia: Mobile 3d Handled Server-Side?

Written November 16th, 2009

Hey all,

I’ll have this week’s Monday Movie up shortly.  I just wanted to make a quick post with this link.  Turns out nVidia’s RealityServer is slated to handle the 3d rendering server-side and then pipe the result to devices that lack the power to do it locally like mobile devices or netbooks.

This has huge implications for mobile and web-based gaming.  Take a look at the whole article here.

RealityServer is Nvidia’s attempt to bring 3D to any computing platform that supports a browser or standard Web services calls, including netbooks and smartphones.

By moving the CPU-crushing rendering requirements of creating high-resolution images and animations off of the client and onto a back-end computer, Nvidia hopes to bring complex graphics applications like fluid dynamics, architectural design, real-time product styling and design, 3D video games, to computing platforms that don’t have the processing power to run them locally.

Downloading, Viewing, and Editing YouTube .MP4 Files

Hi everyone,

I just spent the last 3 hours wrestling with YouTube’s .MP4 file download feature.  It turns out that these files are encoded in AVC1/H264 format with the audio in ISO/MPEG-4 Advanced Audio Coding (AAC).  This post is to show you how to download these files, view them in Windows Media Player or VLC, and edit them in Virtual  Dub.  Luckily, you don’t need a converter and you certainly don’t need to buy any programs.

What makes this so difficult is that the H.264 format is not natively supported in many places, so you need to take special steps in order to accommodate.

To Download YouTube .MP4 Files (AVC1)

Downloading MP4 Files From YouTube is Pretty Easy

Downloading MP4 Files From YouTube is Pretty Easy

In order to download these files, you just need to go to your My Videos section, and you’ll see the “Download MP4″ below each video.  Just click that and you’ll be prompted to save the file somewhere on your computer.  Note you can only download 2 of these every hour, so if the button disappears don’t worry.

If you’re looking to download videos that aren’t yours, you can do that too.  Visit GoogleSystem (the unofficial blog) and they’ll show you a few different ways of setting that up.  The short answer here is to just drag this link to your bookmarks bar, and click on it when you want to download the MP4 of a video from a YouTube page: Download as MP4.  When you click on it, a link will appear in the video info that allows you to download the MP4 file (tested and confirmed as of 11/14/2009).

To Watch YouTube .MP4 Files (AVC1)

Download the VLC Media Player

Things get only a little trickier here.  The short answer is to download and install the VLC player.  I personally certify that it’s one of the best written pieces of software I’ve ever come across.  Zero malware or spyware, it’s completely free, and it’s very powerful.  Basically if the file or disk can be played, this program can probably play it.  Music, videos, DVDs, you name it.  It also handles internet radio stations and saved a puppy from a burning building last week.

The long answer is to read the next section where you download the K-Lite pack of codecs (small files that enable your computer to read and write special video formats).

To Edit YouTube .MP4 Files (AVC1) in Virtual Dub

Download the K-Lite Codec Pack

Download the K-Lite Codec Pack

So here’s where I got massively hung up.  It turns out that FFD show is not the solution, and neither is the Quicktime plug-in.  Your hope lies in two downloads:

  1. Download and install the DirectShow plugin for VirtualDub (aka DShow or DS).  This will connect VirtualDub to the codecs that you’ll install next.
  2. Download and install the K-Lite Codec Pack.  It contains everything you need.  You may need to uninstall any old versions of FFDShow.

Once you have these two installed and you’ve rebooted, you should be ready to go.

  1. Fire up VirtualDub and select File>>Open Video File…
  2. Under “Files of Type” (where you’d ordinarily filter the kinds of files to see in the file browser), select “Direct Show Input Driver”.
  3. This will remove all the files from the browser, but don’t worry.
  4. Type “*.*” or “*.mp4″.
  5. This will show your YouTube file, which you can double-click and begin editing.

This may sound super convoluted and that’s because it is.  However, you can now open and edit your YouTube files without any trouble.

3dsMax mental ray Water Surface Tutorial

This technique is a favorite of mine for its simplicity and effectiveness at creating a convincing water surface.  Remember, though, that you won’t be able to see below the surface because the material setup in 3dsMax is opaque.  At least it’s fast to render!

This tutorial will guide you to achieving a fairly realistic open water effect which can even be animated, using the ‘Ocean’ shader from the Lume Library.

3dsMax Tire Modeling Tutorial

This is one of the more interesting tire tutorials I’ve found. While it’s not the easiest or the clearest, I really liked the outcome and unusual application of the FFD modifier. I’d call this an intermediate/advanced tutorial so if you’re still a little hazy on certain aspects of modeling you might shy away from this one.

Pretty interesting results from this one.

You can start the treading from box modelling or splines. I personally use splines for 90% of my work, but if using splines then you will need to tidy up the model to clean up the geometry…

I know I’ve already covered this topic to the point of making you physically sick, but Luciano Iurino does a fine job describing the technique as well.  In this video tutorial, he talks about how to create circular holes in a 3d mesh using a few different techniques.  As always, 3dsMax gives you 10 ways to do just about anything!

This tutorial shows how a perfectly circular hole can be cut into a mesh using the Editable Poly tools alone. It demonstrates a quick, clean and effective way of creating holes that avoids the often messy results caused by Boolean operations.

Free, High Res Studio HDRI Pack

There’s a free HDRI library out there with lots of high resolution images of studio lighting setups. HDRI images are 32-bit graphics that contain luminance information so it’s basically canned lighting setups! Note that these are huge HDRI images (~1000×5000) so they will bog down your computer. Just take it slow and give your computer time to work through it and things will speed up.

It’s free and it’s a torrent, so you’ll want to get a good torrent client if you don’t already have one. I recommend uTorrent; a small, smart little torrent client with lots of good features.

I’ll be seeding this thing for a few weeks, so you’ll always have a peer, but please help me out and keep seeding. It’s not like you’re going to get in trouble with this one. Learn how to use these images with my HDRI Setup Video Tutorial.

Update

I’ve made a number of changes to this torrent that you should know about.

  1. Now includes lower resolution HDRI images.  The originals are too large for ordinary production so you can work with the lower resolution versions first and then swap out for the high resolution versions when you’re ready to take a final render.
  2. Now includes 8-bit versions for the same reason as above.
  3. Now compressed as a self-extracting .exe file.  I know this is creepy, but it’s the most efficient way. If it were a .zip file, it’d be almost 50% larger.  Please trust me.

If you’re really worried about the EXE or are on a slow connection, You can download the original 230mb file here.

Click this link to download the HDRI Torrent File. It’s a legitimate torrent so you’ll need a torrent client. Alternatively, you can click this link to download the massive file directly, but if at all possible, please try the torrent first.

Hey Everyone,

In this Monday Movie we’ll be looking at how you can render panoramic HDR images in e-on software’s Vue 6 Infinite.  It’s a great program for rendering natural landscapes and skies.  A fantastic addition to any pipeline (though if you’re really crazy you can get their Ozone plugin for 3dsMax).  Next week we’ll look at how to bring these 360-degree images back into 3dsMax for use as backgrounds and illumination maps.

Dielectrics and Glass (Physics_Phen)

This is a detailed dive into some basics of Glass material and the Dielectric shader in mental ray.  Worth a look when you’re in the mood for a lecture.

For readers “too used” to using raytrace glass this tutorial will seem quite alien in the beginning, and the methodology of modeling the objects utilizing these two materials will definitely appear even more alien. Both the Dielectric Material Shader and the Glass (Physics_Phen) are closely related to each other, though technically the glass ((physics_phen) also known as mental ray glass) is not a shader.

Modeling Low-Poly 3d Foliage

This was one of my favorite tutorials that I’d give to students learning how to model.  It’s a fairly basic plant modeling tutorial that goes into detail for both Photoshop and 3dsMax.  You can really get a lot of mileage out of this workflow because it can be used to create a wide variety of plants.

We are going to create this orchid thingy. So take a good look at it, because we need to store its form and colors into our brain.  Now start a new photoshop image and add a green background. You should always choose the dominant colour as your background color…

Modeling a 3d Toaster in 3dsMax

Modeling a 3d Toaster in 3dsMax

I found my old toaster tutorial on 3dTotal and figured I’d give it a link.  It’s a very slow paced beginner’s modeling tutorial.  Great for people just starting out with 3d Studio Max.

I actually remember when I was starting out with 3DSMax and I realized there aren’t enough tutorials out there that really walk you through every click, movement, and heartbeat of production.  That’s why I decided to model a toaster and document every process along the way.  With any luck, if you follow this tutorial, you should end up with something that looks like my toaster here.

P.S. I’ll be going through various 3d tutorial libraries I know and cataloging the good ones here.  It’s a good thing to do because a) people don’t find the good tutorials if I don’t post them, and b) I’ve always wanted a place that I can go to find my favorite tutorials.  I figured maybe you’d appreciate it too.  :)

Panoramic Rendering and HDRI (Part 1)

Hey everyone,

In this block of 3 video tutorials, we’ll be looking at how to render and use panoramic, 360-degree images in 3d Studio Max.  This week is part 1 where I cover how to render these “fish eye lens” images and save them out as high dynamic range images (HDR or HDRI).  It’s pretty easy to do in mental ray- just apply the “Wrap Around (lume)” lens shader, and you’re done!

In part 2 we’ll cover how to render great backgrounds with e-on software’s vue.  Finally, in part 3, I’ll show you how to bring those big renders back into 3dsMax and use them as image-based lighting.
