Of cours, this isn’t a real relief, but what is real in a computer ? This is really practical to use normal map in games, but in movies too, because it makes renders much faster than using meshes. For our image in based on black and alpha, choose Alpha to ease edge detection.Then Height to Normal Map in Edge Detection.In the Layer window, let’s choose Filter Mask.If the drawing is near the edges of the canvas, increase its size using for example Crop tool with Grow option set.Open the drawing in Krita, If it’s a SVG set resolution.In Blender, our rock material will be the entry of Color socket, and normal map texture will be the entry of the normal map with a normal map node in between. If the active layer is not the background layer, transparency is replaced with the background color of the Toolbox. In our sample, we will use a simple wikipedia black image associated to a textured material get from CC0texture. This results in a special bluish image in which colors represent light incidence. The Krita filter analyses edges et applies a lighting simulations relative to edge detection tangent. The use of a normal map is based on the texture. We mainly have 2 options to create relief : It will be usefull for our 3D animations, or video games. Finally, convert it back to transparency mask, move it under the original layer, merge them together. And then use some filter to make the gray area to fully white. For animation, you’d want to do that with adjustment layers, and I’m guessing you’d have to first bake the mask to a file sequence, then reimport in order to conver to alpha - but I haven’t used the animation features at all so maybe there’s a better way.We will use a Normal Map created in Krita to add relief to a plane, in Blender. Then go to Layer - Split - Split Alpha, then you get a transparency mask, right-click the mask, convert to paint layer. By default when you run this filter white is selected, you can choose a color that you want to make transparent from the color selector. So from my POV, right now the only way to go is to do color math in RGB mode, then once you have a suitable black-and-white mask, convert it to selection or transparency mask. This filter allows you to make one single color transparent (alpha). Natively the only tool I see that is actually intended for selecting colours across an image is “Select from Color Range”, but like noted, that’s not very useful because it’s limited to some arbitrary list of predefined colours, and you can’t see what the result will be when adjusting the fuzziness value. So it would take some messing around with the colour channels for fine control, the cross-channel color adjustment curve could indeed help there. As you can see here, I did catch some of the yellow flame in this selection, too. I do agree that the mask workflow could use some love. It selects great but I needed to hand paint my mask because of all the transparencies it has. This is just I am doing for the funs as I am learning Davinci Resolve currently to edit video. For an animation case I would never try that as a possible solution.īut as a followup to your question to perhaps what makes sense to me for making ranged color selection would be something like this. When I am highly motivated I do what suggested but that burns so much time and if you misstep on the sequence you gotta do it it again so I only do it if I have no other way out. But for an animation I have little time for that. tooltip: Open an existing document (Ctrl+O) Other. Also Photoshop had some somewhat cool tools to make selections that I kinda miss but that is another thing entirely.Įver since I came to Krita tools to select by ranges of something never worked well enough for me so always ended up selecting and making masks by hand most of the time, which is a bit tedious. Opens a file browser at the location Krita saves resources such as brushes to. Well it works yes but what it does is a mystery to me as fuzzyness is very vague and spawns no worthwhile results adjusting it also, there is no logic for me to use it since how fuzzyness expands or contracts in random on how it decides to work.įor me Gimps Color to Alpha is the best to clean color out of a image on a free software and I have Gimp for that command alone. ![]()
