What you did on the video, using the Colour-Override, is a good trick. The problem is that the Blur-Gaussian node cuts the blur with the matte of the original drawing, so that cuts your blur if it goes out of the borders. But that seems like a lot of work to do, isn’t there a better way? A magical checkbox in the the preferences? I could put a small brush mark in the top left corner away from the circle and do the same for the bottom right corner to increase the bounding box of the circle, then I can give those two marks a different, unique color and use a Color-Override to make them invisible. I for the life of me can’t remember what I did in the past to make this not happen. If you are applying the blur to say this simple circle scene of mine, the blur gets cropped at the bounding box. The thing I don’t understand is the issue of the bounding box. That Matte-Blur is nice because you can choose Radial or Directional, change the radius of the blur, you can choose Directional and then choose a directional angle and falloff rate, and you can invert the matte all within this modules properties. It is so easy to just overlook or just not find things at first glance when going into the Node Library. Icanau, now that I am looking through the modules, it looks like maybe the simplest thing is to do a Matte-Resize and a Matte-Blur that connects into the Blur-Gaussian matte port. I think I am confusing myself now, sorry, hope that helps some. I attached it after the Matte’s Blur module and before inputing it to the final Blur. That Negate module that is unattached I was experimenting with to have the matte inverse so that it was blurry just on the outline of the sphere. Here is my attempt to soften that hard circle: You can even give that Matte a Blur to get some gradations or feathering like in that tutorial. Or you can just take a brush and draw with black in that Matte and it will limit the effect of that blur.
Then when you adjust the blur amount it should only blur what is contained in black in that Matte drawing.ĭoesn’t have to be a stroke, you can make any kind of object, here is a case where I just used a circle with a black fill to limit the blur effect. Use a black stroke and input that into the Matte port.
Copy the stroke of that sun into a new drawing layer and play with the stroke of it, increase it, etc. In that tutorial example you could take the sun and in Harmony use a Gaussian Blur.
Howdy, If you use a Gaussian-Blur it should have a Matte input port.
