Shape Modeling Exercise Series - #4 (Twisted Doorknob)

In this shape modeling exercise we take a look at modeling a Twisted Doorknob.



The point of these videos is not to model a complete object but to rather focus on different shapes and issues that you may encounter while modeling. So, essentially, these are exercises.

Hopefully, these videos will help you better understand how to approach modeling certain shapes, and what tools are available in Blender to make things easier.

Timelapse Video: Christmas Ribbon Bow



Merry Christmas and Happy Holidays!

I wanted to try and get something done for Christmas, and barely made it! So, here's a video demonstrating how to create a ribbon bow. This is really an unedited video with no narrative (ran out of time), and it's been sped up to help make up for the lack of editing. Hopefully, you'll be able to learn something from it.

If enough people are interested, I'll reproduce it with a narrative and a lesser timelapse factor.

This is only available online (didn't have time to create the download version, sorry).

Anyway, it's been a great year thanks to all of the support and feedback! Look for 2010 to be significantly more active.

Enhance Your Blender Renders with Textured Lighting

Here's a text-based tutorial that I created to help you spice up your scenes with textured lighting. We’ll take a look at how simple it is to drastically effect the look and feel of your renders by applying textures to lighting. Applying a texture to a light is generally the same as applying a texture to an object. The only difference is that we’ll be projecting the texture into the scene based on the light settings.



Although not a lighting tutorial that goes into great details of the lighting setups, we will take a look at the basic function of the lights within the different scenes. We’ll also cover how to create your own simple textures for the lighting. The last example will show how simple it is to use a video as a light texture.

These techniques will allow you to create interesting light and shadow patterns that can help frame the "story" and context of your scene; thus helping you to create scenes that no longer appear to exist within the all too common CG vacuum. They will also allow you to add subtle variations to your lighting instead of the ultra-clean lighting often seen when using very basic lighting techniques.

This tutorial requires a knowledge of the basics of applying a texture to an object in Blender.

Creating Mesh-based Arches from Curves

This video tutorial will show you how to leverage the power of curves to create smooth polygon-based arches. We'll also take a look at how to control the polycount of the resulting mesh. After covering the basics, there are two short timelapse videos demonstrating a couple of variations on the techniques.

The resulting geometry can be used to help create archways, doorways, architectural support structures, etc.

3D Mesh Topology Tip: Cleanup Those Triangles on Capped Cylinders and Closed Circles

Hello there! It's been a while but, BlenderNewbies lives!

In this topology tip, I want to cover a very easy, but not so obvious, way to get rid of the collection of triangles found on capped cylinders and when you close a circle of vertices. Here's an example of what I mean:



As you may know, it's best to use quads (four-sided polygons) as much as possible in your modeling. In this short study, we'll be converting the triangles shown into quads. There are a couple of important points to note that make this a little tricky, but we'll get to that shortly.

Let's Begin

With your circle of triangles in place, press the A-key until all of the vertices are selected. Then, press Ctrl-N to recalculate the Normals so they all point outward. (Sometimes vertex/face normals can become flipped during the course of modeling and this can cause a number of issues later on so, it's always a good practice to just make sure they all are pointing outward.)



Press Ctrl-Tab to switch to the Face selection mode, making it a little bit easier to select the faces.


Now, as a test, let's see what happens if we select all of the inner triangles and try to convert them all to quads (Alt-J).


You can see that we still have some unconverted triangles. Not good! I'm not sure why all of the selected triangles aren't converted to quads but, let's focus on finding an immediate solution.


Press Ctrl-Z to undo until you get back to having all triangles again. Press the A-key until all faces are deselected. Now, select just two adjacent faces as shown.


Continue selecting pairs of adjacent faces while leaving a pair of unselected faces in between. You should end up with the following selected faces.


Now let's go back to the Mesh menu to try converting the triangles to quads again.


The selected triangles have been successfully converted to quads.


Now, simply select the remaining triangles and convert those to quads.



Here we have the finished version consisting of all quads!



That's All!

Here's a quick video of the entire process:

Feature Demo: Continuous Physics in Blender 2.46

The upcoming 2.46 version of Blender will be packed with so many new features it boggles the mind. Development is happening at a breakneck pace.

Here's a new feature that I only recently became aware of and it's definitely cool. It will be of great use when using Blender's physics simulation features. The new feature is call "Continue Physics" and it's available in the Playback menu of the Timeline window. Basically, it allows you to continue tweaking your scene while still seeing the real-time effects of any physics simulations that are in place!

From Blender.org:

For tweaking physics systems, it is useful to work with the timeline Play button enabled. Making changes will then be automatically be reflected in the results. Further, a new option in the Playback menu, "Continue Physics", will continue the simulating physics system regardless of the current frame. This makes it possible to interact with the physics system by moving collisions objects, shaking a softbody object, etc.

UPDATE - Faster loading video!:
Here's a video demonstration that shows the new feature in action. (MOV, 9.5MB)

The scene shown in the video is available as a downloadable .blend file from Blender.org. The new "Continue Physics" feature is only available in the very latest release candidate for Blender v2.46 (rc4) and, of course, the pending official release of v2.46.

For more info and a link to the .blend file, visit Blender.org.

Using a Lattice to Redesign your 3D Model

Here's a quick video to demonstrate how to easily redesign a 3D model by using a Lattice Modifier. Using a lattice will allow you to make significant changes to the shape of your model without sacrificing the integrity of the mesh topology. You can push, pull, stretch and twist your model with ease.

Here are the basic steps:

  • Start with a model loaded into Blender.
  • Add a Lattice object to the scene.
  • Position it to encompass your model (or part of your model).
  • Subdivide the lattice as needed using the U,V, and W parameters.
  • Parent your model to the lattice as a Lattice Deform.*
  • Manipulate the lattice object to reshape your model.
  • Apply those changes.
  • Delete the modifier.
and you're done!

*(An alternate way to attach the lattice to your model would be to select your model, add a Lattice Modifier, and type in the name of the lattice object in the "Ob" field.)

You can also use a Lattice Modifier during the modeling process to achieve a shape that would otherwise be difficult, and continue modeling your object afterwards.

Lattices can also be used for animation but, that's beyond the scope of this demonstration.

Definitely spend some time exploring the many benefits of Blender's Lattice Modifier. Also, be sure to check out a very similar tool called the MeshDeform Modifier (new in Blender v2.46). This serves the same purpose as a Lattice except that you're not limited to a basic grid-shaped cage. The MeshDeform Modifier allows you to use another mesh of any shape as the cage!

Modeling Timelapse of Bowden Bicycle Frame

Hey,

Here's a quick timelapse video that I created to help one of the BlenderNewbies forum members working on a personal project of modeling a classic Bowden bicycle.



It's not perfect or complete and, there's no audio. It's just a quick demonstration of one way to approach modeling the main part of the framing. There are some errors, but I just left the "camera" rolling . The setup portion is in real-time and the actual modeling part is sped up to keep the video size reasonable. The entire process took about 25 minutes.

I'm sure I'll be posting more of these types of "over the shoulder" videos because I think there's opportunity for learning just by watching the process unfold.

Video Tutorial: Creating a Text Outline Effect in Blender

In this short tutorial, we'll take a look at how you can use Blender to create text outline effects. Our goal will be to have the text appear as two-dimensional printed text as opposed to 3D text.



After viewing this tutorial and studying the included references, you will be able to:

  • Add text to a Blender scene and change its font
  • Setup a camera to render a scene orthogonally
  • Create a window to display your rendered scene using the Image Editor
  • Gain control of the bevel of a curve object
  • Control the anti-aliasing of your rendered scene using the OSA filters
  • Create a text outline effect
  • Remove shadows and lighting from an object's material
and more...

Video: Basic Decaling in Blender



Well, here's another Blender tutorial! This time we take a look at how to apply decals to a 3D mesh object. It's really very simple but, there are a couple of snags you might run into and I demonstrate how to resolve those issues.

Check it out and be sure to let me know what you think by leaving your comments here or, discussing it in the new BlenderNewbies forums.

- TIP ---------------------------------

Daedalus Young points out:

...I found the decal was also showing on the opposite side of the object....

kwk provides a quick solution:
...You can simply use the "ClipCube" option [instead of the Clip option] in the "Map Image" tab of the "Texture buttons" (F6).

Nyrath provides even more details to resolve this issue:
I have found that ClipCube is not quite enough. You have to scale the Z leg of the Empty object so it is shorter than the distance between the center of the empty and the rear face.

In essence, with Clip Cube, the length of the Z leg on the Empty controls how far the decal can penetrate into the object you want to paint. This can be important if the object has a curved surface.

Here's another demonstration of the same technique created by Pablo Lizardo. The sphere that you see is an Empty object with its draw type set to sphere. He also uses multiple procedural textures instead of an image.

Video: Gen3 Tree-Making Tool

This is a demo of the Gen3 tree-generating script. Gen3 is created by Sergey Prokhorchuk (a.k.a. Stager) and we have him to thank for creating such a great tool for Blender.

I've done a lot of research and have found quite a few tools for creating trees that are compatible with Blender. And, because I was able to find so many useful tools (I think I found something like 12 or 13), it's going to be difficult to create actual tutorials for each of them. There are so many things to consider when creating a tree and that usually translates to a lot of parameters in these types of applications. So, in order to cover them all in a reasonable amount of time, I've decided to present quick demonstrations, instead. The bonus aspect of this is that I'll share with you all of the treasures of information that I've collected in my search for these tools. This should save you quite a bit of time in getting up to speed with the applications.

This video covers:

  • Introduction to Gen3
  • The Basics of Using Gen3
  • Speed Tips
  • Creating/Trimming a Quick Shrub
