Reset maya windows script

2014-09-02 09:25:41 admin

Detached maya windows have an annoying habit of getting lost when switching from a multi-monitor window to a single monitor setup!!! (or just in general, when they get lost under other application windows or  the start bar >.<)

All hope is not lost however, here are two solutions to the problem:

 

  • Close maya and delete the window preferences file (annoying)
    • This file is call windowPrefs.mel, and is located in your default “prefs” folder – This file basically stores the list of the last locations  of the default maya windows. It gets updated  when maya exits.

 

  • Run this maya script I cobbled together (less annoying)

Global Game Jam 2014 - Under a Glass Bell

2014-02-23 17:27:49 admin

Game Concept

players are in a cell captured by an evil overlord. In order for 2 people to be freed, you have to kill 2 other players. Each object in the room has an item behind it which will either help you (e.g. knife, gas-mask) or it will kill you / everyone without a gas-mask (booby trap, or poisonous gas).

The main mechanic of the game: Player one puts on headphones and is given a message with some information about the location of an item. The headphones are then passed to a player of their choice who hears some more information. and this keeps on going until you think you have enough information to make a choice and take / trigger the item at a given location.

You can move around and interact with objects / players at any time. Everyone is given partial information so that you will have to form alliances with other people playing to get all the information you need. Sub mechanics: You can also block locations from other players by occupying them (walking up to them) The game is round based. Up to two players can win a round. First player to 3 points wins, to get ahead you need to find a gasmask and trigger the gas trap to kill three other players.

    Photoshop Path To 3D Mesh (OBJ export)

    2014-02-23 15:56:26 admin

    Overview

    Over the last week I have been working on a proof of concept script that exports Photoshop paths to polygonal meshes directly. The script can export paths directly or it can generate them automatically from the transparent areas of a layer. This script has only been tested with Photoshop CC thus far.

    Uses

  • Creating planar meshes with complex curves / shapes.
  • Automatically creating optimised mesh shapes which match the shape of a sprite texture.
  • Demo

    Download or Contribute

    The script is in an alpha stage. If you would like to give it a try, or if you would like to contribute it is available here:

    Usage Instructions (exporting a path)

  • Create a vector path, making sure the paths exist on the Work Path layer
  • Save your document as a PSD (required step)
  • Download the javascript file in the link above
  • Click File -> Scripts -> Browse. Load up the script available at the link above
  • Adjust settings accordingly. Be sure to disable “Auto Generate” to export the path created.
  • Sample rate determines the amount of vertices to place. Padding Radius does nothing in this mode.
  • Usage Instructions (auto generating from a transparent layer)

  • Select a transparent layer
  • Save your document as a PSD (required step)
  • Download the javascript file in the link above
  • Click File -> Scripts -> Browse. Load up the script available at the link above
  • Adjust settings accordingly.
  • Sample rate determines the amount of vertices to place. Padding Radius expand the selection areas about the object on the layer.

    Better HDRI Maps for Final Gather (General Technique)

    2014-01-28 07:32:31 admin

    Prerequisite knowledge

    • Basic knowledge about rendering techniques.

    What you will learn

    • How to process an HDRI map for final gather rendering
    • Learn about a free tool to do HDRI processing  that would normally require very high end software (e.g. nuke)

    What you will need

    • Picturenaut (free, and a mac version is on its way )
    • Banty’s Toolkit
    • An HDRI image to process. A good demo set can be found here for free.
    • Windows PC to follow the tutorial.
      Note that the information can be applied to any set of tools, so don’t be discouraged  if you are on a mac.
      If you are aware of mac substitutes for this tool, let me know so I can add it to the  tutorial.

    The problem to be solved

    Generally speaking final gather works by sending out a ray from the camera  to an object and then bouncing that ray to the environment to get an approximation of the indirect lighting contribution.

    HDRI maps are inherently problematic as  you could have  pixels  that are extremely bright and extremely dark next to each other. If a ray hits a bright pixel on the  environment map and the ray next to it hits a very dark pixel, you will get splotches in your render.

    The only solutions to this are:  brute force sampling (bad)  or processing your HDRI image to resolve the problem (better)

     

    The solution

    Create 2 HDRI maps.

    The high resolution one is used for  reflections.

    A secondary HDRI map is generated for use as your environment map.  This is done by reducing the resolution and applying a diffuse convolution filter onto your HDRI map. This may  appears similar to a gaussian blur but the key difference is  that it preserves the edges of the map and appropriately approximates the indirect lighting contribution within the HDRI map.  Your final file will will be of a lower resolution and will give you better results with less samples.

     

    Setting Up Picturenaut & Banty’s toolkit

    • Download the appropriate version.
    • Run the installer
    • If you are requested to, download and install the .net framework 3.5
    • Download the Banty toolkit
    • Extract the contents of the plugins folder within the zip to \InstallDirectory\Picturenaut\plugin-ins\hdrshop\

    Processing an image

    • Open Picturenaut
    • Click File > Open File of your choice

    hdr_before

    • Click Filter > HDRShop > Diffuse SH
    • Run the filter when it pops up
    • Save the new image and load it as your environment map. It should now look a bit like this:hdr_after
    • As a proof of the technique, you can take a look at this link
    •  file containing spherical harmonic coefficients is also created. if you have the appropriate tools, you can use this information to approximate indirect illumination in real time,  but that is  way out of the scope of this tutorial.
