This is the latest game I have worked on as a 3d modeler at Tap4 Mobile, a Back River Studios 3rd parter. I worked on lots of environment plants and props.
Everyone knows how boring it is to make texture atlases. To make this task less painful, I have used some of my spare time to create a tool that I named Easy Atlas.
Easy Atlas uses Photoshop to merge several textures into one single texture atlas and Maya to rearrange mesh UVs.
If you think this tool would be useful for you, please feel free to download it from HERE.
The following video shows a quick demonstration of how it works.
This tool is compatible with Maya 2014 and upper versions. Any Photoshop version from at least CS3 version should be supported.
Please be aware that this is not a commercial product. It was developed in my free time and, althought I have the intention of giving support for it, I cannot garantee I will be readly available.

This is a great little piece of animation exercise made by Will Eades using my rig, Alex. :)
I’ve been rigging a character in my spare time and I’d like to share it with the animation community.
Alex’s body has been rigged with Advanced Skeleton and you will find heaps of information and training videos in the Advanced Skeleton home page. The face was custom rigged and I tried to keep it simple and powerful. Lets see what comes out of it. I’ve built a synoptic – or character UI if you will – to make the control selection easier.
Donwloads on hold. New version to come soon.

As a technical artist, I have worked with Maxscript for a while now and it has been an awesome way to automate repetitive and complex tasks in order to increase the productivity of 3d artists by keeping them focused in the important things. Technical artists make huge effort to keep artists away from boring technical aspects of a production.
However, while Maxscript is quick to learn and to create tools, its use is not suitable for the kind of job that needs high performance and complex calculations. If something like real time mesh deformer is what you need, 3d Max provides you with its lower level software development kit (SDK).
And this is what I wanted to get into to expand my capabilities in the tech art field. Although I have been working with games for a while, the experiments I have been doing with 3d Max SDK are definitely more suitable for VFX on movies production.
Continuing with my first experiments with 3d Max SDK, in this post I will show some of my progress and publish some more details behind my plugin to be. Please have a look at the following video which contains a compilation of my progress.
Low performance with high poly meshes was one of the problems I faced when creating my CPU version of the plugin. At that point I thought of using fancier octree algorithms to reduce the plugin computation time or caching the mesh deformation but, very curious I am, I chose going another way instead. I decided to use the code I had at that point and try to adapt it to use the power of GPU processing.
For that I worked with OpenCL framework – ATI version of Nvidia Cuda – which demands you to know about video cards architecture. Basically, the advantage of using GPU against CPU is that GPUs have dozens of stream processors – 1120 in my video card case, an ATI 6870 – while CPUs’ standard is something around 1, 2, 4 or 8*. Using all these computing units is not so trivial. It is needed to manage the parallelization of jobs sent to the GPU.
The OpenCL framework only gives support for basic computations though and things like ‘ray intersect mesh’ functions given for free in the 3d Max SDK had to be written in OpenCL (C like) language**.
In the video above I present the result of my experiment where my plugin runs 10x faster in the GPU with higher poly meshes. The greater the number of computations to be made, the greater the difference becomes.
This is my first attempt creating a plugin with 3d Max SDK. The work is still in progress but I am pretty happy with the outcome so far. The main deal of this plugin is to create the effect that simulates muscles sliding underneath the skin. My plan now is to polish this plugin, add some more functionalities and post more illustrative examples here soon.

In this post I’ll share with you a very simple tool I had to make for a personal project. Its function is to save/load the skin weights from/to a mesh. OK, I know 3d max has its own way to do this, but there’s one special thing here. It’s possible to load a saved skin to a couple of selected vertices. It can be useful when you have a mesh being skinned by 2 artists at the same time for example. The script is based on vertex position instead of vertex index, but I am willing to add this and some other functions soon. I hope it can be useful for you guys as well as it was for me. Please check the video below out to see how it works.
What it does:
- export weights for the whole mesh
- import the weights for the whole mesh or just for the selected points (selecting points inside the skin modifier)
How to use:
- after running the script a toolbox will be launched
- MAXScript -> Run Script -> skinTool.ms
- the rest should be straight forward
- WARNING: all the export/import operations must be done in the same pose (usually the T-pose for characters)
- the information is processed based on bones’ indexes – bone order in the skin modifier matters

In this post I am publishing a study of an auto-rigging script I have made a while ago. The goal of this study was to create a tool that could quicly set up a rig with my preference of features. This script sets up a rig with IK/FK arms (with blending based in Paul Neale setup), IK legs and reverse feet from a given reference. I didn’t go futher than that because the point was just to study some scripting at that moment.
If you want to try this script anyway, a reference of bones will be needed. Anything can be used as reference. In the following video you will see a very simple chain of bones, a Max Biped and a Max CAT being converted to my set up. Just for the record, the idea of converting an existing Biped reference into a custom rig was taken from Daniel Lara.
What it does:
- from a given reference, it sets up a rig with features of my choice
How to use:
- create your reference and run the script
- MAXScript -> Run Script -> rigMachine_v02.ms
- map the bones
- if you want to use a CAT reference, please create a dummy at the end of the toe and link it as child of the toe
