…I should really learn how to use Twitter properly.
Over the past three months or so, there have been quite a few very encouraging and exciting developments in the Fusion community. Just in case any of them have been overlooked, I thought I'd take a few minutes out of your day to tell you about them.
The first thing I'd like to point out is the release of Reactor, a package manager for Fusion. Reactor makes it dead easy to find, download and install new tools. My own Glitch Tools are available there, as are several other offerings from Muse VFX.Continue reading →
Commenter Steven Newby asked for a deeper look at the Reflect node because the existing tutorials he could find on YouTube apparently only examined reflections on a sphere. In this article, we'll take a detailed look at Reflect3D and how to use it to best effect.
Regrettably, I'll need to use Fusion 8 for this demonstration because I'm on a loaner PC that can't run Fusion 9. I therefore won't be able to provide screenshots for the use of the new spherical camera, but hopefully my description will suffice. To get started grab this coffee cup geometry, which may be familiar from the 3d workspace chapter of the upcoming book. Import the cup and saucer into the scene using the File > Import > FBX Scene… command.
The default settings are fine, so just click OK to get five new nodes in your Flow: Two Blinn materials, two FBX nodes, and Merge3D that weds the geometry together. The scale of the geometry is a little big, so in the Merge3D, switch to the Transform tab and reduce the scale to 0.1. If you like, you can also move the Y Offset control to put the bottom of the saucer at 0. Both of those things are optional, but I find it more comfortable to work that way.
I'm not concerned with integrating the cup with a photograph this time; instead, let's see if we can't make a really nice product photo image like you might see in a catalog. We'll go for a super shiny and clean look.
Fusion 9 has been released, and the retail price for the Studio version has dropped to a mere $299. From this article forward, I'll be using Fusion 9 Free on Windows 10. Although the new price point makes Fusion Studio more accessible than ever, I will continue with the assumption that the student is using the Free version. Studio-only features may be detailed in supplemental chapters on the website.
In the previous chapter, we used Fusion's 3D system to match the position and angle of view of the physical camera used to take a photograph. We also did a little bit of grain and focus matching to help integrate the coffee cup into the plate. In this chapter, I'd like to expand on those ideas by discussing the various qualities and defects that film and video cameras produce and how to mimic them for the most convincing composite possible.
I have arranged these concepts roughly in the same order that they affect the image. When setting up a composite, it is helpful to arrange your nodes in a similar order in order to maintain realism. For instance, you wouldn't want to perform a lens distortion before the camera shake because the lens is attached to the camera and will therefore shake with it. Likewise, grain should be applied after all optical effects because it is a property of the sensor or film and therefore affects almost everything, including such things as lens flares and blur.Continue reading →
MultiMerge can perform a Merge with up to 64 Inputs. Every time a new Input is connected, a new one is created. The composite is created iteratively, so each additional image is Merged with the results of the previous Merge operations. At present, every layer gets the same Apply Mode and Operator, and the Transform controls are not exposed. UPDATE: There is now a Blend control per layer, and the connected Inputs are displayed in the Control Panel for better clarity.
Control Panel inputs do not automatically update when a new Input is added. Deselecting and reselecting the node causes the new controls to appear.
Held Out mode doesn't work and throws an error in the console.
Add an Apply Mode/Operator control
and a Blend control for each layer.
Implement Transform controls—I'm not sure exactly how these should work. On-screen widgets only apply to the highest-numbered input, perhaps?
Implement Depth Merge (low priority)

Many thanks to Stefan Ihringer and Isaac Guenard for providing some (most) of the code on which this tool was built. Also to the community at We Suck Less for helpful tips.
A couple of weeks ago, I began to see signs that someone was attempting to attack my online profiles and accounts. Rather than wait until my security had been broken, I decided to take steps to get out ahead of the hacker by adding additional layers of protection to my accounts and reading up on the latest best practices in online safety. "An once of Prevention is worth a pound of Cure," as Poor Richard said. In this article, I will share some of what I have learned and offer some free advice and tools to help you.Continue reading →
This is the seventh in a series of articles about OpenCL Fuse development, following the guidance of Vivo & Lowe's Book of Shaders (BoS). In the previous article, I learned how to transform shapes by manipulating the coordinate system. This article expands on that approach by tiling the coordinate space.
I am going to get a bit adventurous this time by adding some image inputs to the Fuse that can be used to define patterns with exterior images. I'll also look into passing information from one kernel to another, allowing me to use any of the previous modes as a source for tiles.Continue reading →
This is the sixth in a series of articles in which I explore the lessons recommended by Vivo & Lowe's Book of Shaders in the context of custom Fuse tools for Blackmagic Fusion.
In the previous article, I learned how to use OpenCL to create some basic shapes, and during that process I set up some Translate and Scale controls so that I could use the Viewer widgets I'd set up to control the shapes. I mentioned that I suspected my approach to scaling was unorthodox, but as it turns out from reading the BoS's 2D Matrices chapter, I did it exactly right: Rather than moving the shape, I modified the coordinate system, effectively reshaping the world around the shape. In so doing, I actually ran ahead of the lessons a little and solved 2/3 of this chapter already.Continue reading →
This is part five in a series on OpenCL Fuse development for Blackmagic Fusion. I am attempting to convert the lessons from the Book of Shaders into working Fuses, learning a bit about programming and parallel processing as I go.
As I said at the end of the previous article, I'm skipping BoS Chapter 6 on Color because this series is aimed at compositors, who hopefully already understand that topic fairly well. If you're an engineering type, though, definitely take a look at that chapter and work through the exercises; they'll do you good! I am now moving on to drawing shapes.
As usual, I'm looking ahead toward where I think I'll want to expand on what I learn, so I'll begin by adding some more controls to the Fuse, even before I start looking at the OCL code. Obviously, I'll need to add another button for this mode. For now, I'll call it "Rectangle," although I might change it to "Shapes" later on and add another sub-mode multi-button like I did for the Interpolation mode. I also want some in-Viewer controls for transforming the shape, shells for which are not available in my template. To the right you can see a version of the control panel that's even a little further advanced than this article describes, with controls for Soft Edge, solid or hollow shapes, and a mode that creates a regular polygon.

I promised in my initial review of Fusion 9 to do some speed tests. Blackmagic claims that every tool has been rewritten to offer GPU acceleration with OpenCL. Naturally, that's of great interest to pretty much everyone, especially those of us with access to overpowered Titan X cards. Alas, the news is not so good.
