The newest version of RayFire will support an interesting “Stick to Mouse” feature that will make it much simpler to distribute and destroy fragments. The new demo video shows interactively spreading a fractured object across a street, and then interactively flinging pieces against objects watching them shatter realistically.
3dsMax and VRay both have a tendency to crash when you exceed your system memory, that’s a long establish fact that frankly isn’t unique to rendering packages. But there are things you can do to reduce your memory usage, options buried deep within with cryptic names like “BSP Trees” and “Face/Level Coefficient”. If you want to know how to tweak these options to best effect on your rig, check out this great article from RenderStuff.
As we know, V-Ray uses the organization of the scene geometry in a form of a BSP tree to accelerate the raycasting process. It is logical to assume that the deeper our tree structure, the smaller its leaves, and the smaller the units of the geometry each leaf contains, then the more space in memory we need to hold tree’s branches and the greater is the potential raycasting speed it can provide.
However, there is a limit in such acceleration. After a certain threshold, further division is not reasonable, since the excessively branched structure of a BSP tree makes the work with itself too difficult. The raycasting algorithm may spend the computational resources for walking through the huge BSP tree, ruining all the gain in speed.
Over on YouTube, you can see some great videos of the new RayFire. In particular, they have some fantastic examples of the new Dynamic feature in action.
Graphicspeak has a great Success Story from Jeff Patton, freelance CG artist known for his mechanical imagery for some big names. Discussing a recent project for Mercedes Benz, he took his hour per frame renders in 3dsMax and converted them to iRay, and found renders completing in mere minues.
Patton said, “After I finished my first full Mercedes Benz project with the new Nvidia setup, I was stunned. Rendering out the images at 6K in the past took me about an hour per image using the CPU. With Iray and Quadro, I was able to knock that down to eight minutes — EIGHT minutes! It’s a huge benefit to be able to turn things around that much faster.”
The workstation he used had an Nvidia Quadro 6000 and a Tesla C2070 GPU, both fairly high-end cards. Quadro 6000‘s run around $4,000, and a Tesla C2070 runs around $2,500. That same $6,500 could have bought 3 of the BOXX renderPro systems. With a linear improvement in rendertimes, he could have gone from 1 frame an hour to 4 frames an hour, against 7 frames an hour with the iRay solution. Sounds like a win for iRay & CUDA to me.

FXGuide talks to two of the guys behind some of this year’s SIGGRAPH Computer Animation Festival entries, including some great details with Damian Nenow on his impressive geometric clouds in 3dsMax.
Most people would do clouds now as volumetric renders, but I didn’t want to use a volumetric solution because it’s hard to control them and know the final shape. So I created them first as low-poly geometry based clouds. Then, using the Vertex Color Tool in Max, which is an almost forgotten tool, I could use the vertex color data to illuminate the clouds in the way I wanted.
The way it worked was I created these low poly elements, then covered them with thousands of sprites. They had alpha channel textures on them. You can then add photorealistic textures, like photographs of fragments of actual clouds, or you can add hand-drawn ones, which is what I did. So that’s why they look pictorial. I was able to get very fast render times – between 10 to 30 seconds just using a simple scanline renderer.
The Vertex Color tool is far from forgotten in Scientific visualization arenas, we use it regularly here. I can easily see how it’s not particularly useful amongst “normal” animation people tho.

If you works lots with Point Clouds (Volume Rendering, Laser Scans, fluid simulations, etc) but have been thwarted by 3dsMax’s lightweight (nonexistant?) support for them, previously you had to go look elsewhere for tools like Krakatoa. Autodesk has released a new “Labs” product called “Project Helix” that boosts this lacking area significantly.
Bring your visualizations into context with Project Helix, a powerful technology prototype enabling display and rendering of 3D laser scanning/LiDAR data sets with Autodesk® 3ds Max® and Autodesk® 3ds Max® Design software. With the 3ds Max Point Cloud Tools you can more quickly import as-built site references to help evaluate and visualize your designs in the context of their surrounding elements. Point cloud data sets are often created by 3D scanners and represent a set of measured vertices in a three-dimensional coordinate system. Using an automatic process, these devices measure a large number of points on the surface of an object and output a point cloud as a data file.
It’s only available until December 20th, but hopefully they’ll integrate it into the next version of 3dsMax.

If you’ve upgraded to the new 3dsMax 2012, you might want to try out this great plugin that helps build image-based lighting maps.
IBL Optimizer V1 allows you to use Images Based Lighting at 3dsmax2012 to composite real HDRI´s with Computer generated Objects.
A wealth of options and some impressive results..
Announced back at SIGGRAPH, E-On software has just released Carbon Scatter for 3dsMax. Combining their digital nature systems with instancing plugins, you can now create massive populations in your scenes with just a few button clicks.
Carbon Scatter is the easiest and most straightforward solution for creating complex and detailed populations using the native instancing technologies of 3ds Max. Versions of Carbon Scatter for Maya and Cinema4D* will be available shortly (an Open Beta will be released in the coming weeks).Carbon Scatter integrates e-on’s patented EcoSystem™ algorithms directly inside the end user’s favorite 3D application, allowing the population of native scenes with millions of instances and rendering them with the user’s renderer of choice.*Versions for Softimage and LightWave are under consideration.
Key features include automated “smart” scattering, painting, and many ecosystem controls. It’s available for Windows systems now for $195 to $395, depending on features.
Get the full details, after the break.

Autodesk has a big announcement today, the new Entertainment Creation Suite Premium 2012, including new versions of 3dsMax, Maya, Mudbox, and more! The new version a new multi-threaded graphics core, part of the “Project Excalibur” initiative . This gives you not only better performance, but better visuals during interactivity making the whole suite easier to use and faster to get to your desired objective.
“The first time I loaded a scene in 3ds Max 2012 I could see the soft lighting and shadows right in the viewport. This had the biggest impact on me. I suddenly felt more productive; like the barriers to my creativity were falling away,” said Stephen Lebed, 3ds Max beta tester and visual effects supervisor at MECHnology.
3dsMax will be available in April, with 3dsMax Design later this month. Get the full press releases for these products after the break.
A pair of new plugins from AR-Media allow you to view your Sketchup & 3dsModels in Augmented Reality space. In addition to simply viewing the models, they’ve added some impressive Object Occluding technology that I’ld like to know more. You use their plugins to convert your models or scenes into their proprietary format, and then you just need their freely available ‘ARMedia Player’ to view the models.
The bundle provides users with an advanced visualization functionality which serves two main purposes in the design life cycle:
- Help to study and analyze virtual prototypes in real environments
- Communicate 3D projects immersively and astonishingly
All you need to make AR-media™ Plugin work is a personal computer, a webcam and a printed code attached to the software. A wide range of Head Mounted Displays, including the Vuzix® CamAR, eMagin, i-glasses™ are also supported.
For folks in product design this could be a great tool. You can download trial versions of the plugins from their site. See the demonstration video below.
