Specular Maps Tutorial

by

There is information about the Materials System in the SL Wiki and Forum. The part I found interesting is the link to: Brief Considerations About Materials. This is an article by a teacher for a Post-Graduate Course on Game Art.

The emphasis in this article is on Specular Maps. This is something many of us have little knowledge about. But, the specular map is going to be far more complex than the normal map. This is the area where knowledge will be key to making nice object textures or great object textures.

Second Life Normal Textures Tutorial

by

The Materials System Project is steadily progressing. We do not have an ETA, yet. We do have a bit of a place marker in that we are told projects are moving in the order of; Chat HUD User Interface, Server Side Appearance, and then Materials. So, we know it will arrive soon, but is still a ways off. If we want Materials to work the way we want, we need to be able to provide feedback during the coming Beta Phase of the development process.

To be able to give feedback we need to understand how to make and use of Normal and Specular Maps (or textures – interchangeable words in this case). So now is probably a good time to start learning the basics to allow us to participate in the beta testing without looking too ignorant.

Blender 2.66a Dynamic Topology Tutorial

by

This is a 15 minute video on Dynamic Topology. It shows the difference in how we work with and without it.

[youtube HKuOIfNKz8g]

This tool can be used for adding AND REMOVING polygons.

This tutorial also shows using the Symmetry tool that is part of dynamic topology.

Once you see the tool in action, you’ll understand how handy it will be.

(There is a bug in the current Chrome Developer. The URL does not always update. It depends on how you move from page to page. On YouTube the URL sometimes fails to update. I’ve been able to reproduce the failure, but not consistently. So, I got the wrong YouTube ID for the original posting and didn’t preview the post. It was short. Sorry.)

More on 123D

by

I just found 123D Catch and wrote about it in: New 3D Modeling Tool – 123D Catch Review. 123D Catch is a program that runs on iPhones, iPads, and desktops. It allows you to turn photos of an object into 3D models that can then be ‘printed’ as real physical models. Of course Second Life™ users would use the result as 3D models with textures for import to SL.

However, 123D Catch is only part of a suite of 123D programs being created by AutoDesk to capture the consumer design market. We have new technology like Cubify 3D Systems that can turn 3D models into real life objects.

The suite of programs is free and consists of:

  • Catch – Uses photos of real objects to generate a 3D model.
  • Design – Create 3D models on your Mac, PC, or iPad
  • Sculpt – 3D sculpting
  • Make – unique projects using incredible slice or fold techniques.
  • Creature – Used to create… well… creatures.

New 3D Modeling Tool – 123D Catch Review

by

I came across an article on a new way of building 3D virtual worlds. (Thanks Hamlet NWN) Well, may be not so new, it came out in 2011 I think. But, the process, new to me, is being used to create the independent adventure game: Rustclad. The development team has a video out showing the process they are using and early scenes from their game.

You can see they are using a more organic style than we typically see in Second Life™. Sculpties were introduced to Second Life to enable the creation of this more organic style. I am not sure we have ever taken advantage of sculpties as intended by the creator of them: Karl Stiefvater (Qarl Fizz, formerly Qarl Linden). May be I’ll ask him some day.

GIMP Normal Maps

by

Materials are coming to Second Life™. Part of the feature is Normal Maps. So, if you want to take advantage of the new feature you are going to need to learn how to make Normal Maps. There is a new tutorial that teaches one how to use the free GIMP image editor to make them.

Indigo Mertel Plurked the link. If you’re Plurking, friend Indigo. The video is 23 minutes long.

vscorpianc made the tutorial. Vscorpianc has 277 videos on YouTube. It is a nice collection of GIMP and Blender tutorials.

She does an excellent job and speaks very well. None of the umm… errr… uuhh… or false starts and redo’s.
