Inherit alpha takes the alpha of lowest layer in the stack, and uses this as a transprency mask. This means that lighter colours will lighten the overal colour, and darker colours will darken the overal colour. Everything below that set to multiply(so black results in black), and everything above that set to Screen(the inverse of multiply). Hard Light, on the other hand, will have 50% grey as affecting nothing. Multiply means that it will multiply the numeric values of the colours, always resulting in a darker colour. Now, if you set the shadow layer to multiply, or to Hard Light. We fill it with 50% grey:Īnd then we set said layer to hard light(you can find this under catagory 'light’. Remove/Hide the background, we won’t need it: The split layer function is underneath layers->split layer(at the bottom).

Then, I split those up, though this step is not mandatory: I’ve used the g'mic recolorize filter to quickly colour this in. The traditional diffuse material is chalk, it’s called diffuse because it spreads out the light into all directions.ĭiffuse materials are pretty easy to draw: we only require a self-shadow, cast shadow and indirect light to make it realistic. This is important because when it comes to materials, the use of your shadows is 80% of the work, so you should spend extra time on the shadows for this. In this tutorial, I will make use of a method that separates the shadow and light from the colours. We’ll go into these a little further in this tutorial. This is the light that is bouncing off other objects, and thus appearing in areas where the direct light does not reach. This is the shadow created by another object blocking the light. Self shadow happens due to the light only bounding off certain sides of an object, and not being able to reach others.Ĭast shadow.

You can get the first beta for Krita 2.9(or later versions when the time comes) from. This tutorial will also be done with Krita 2.9, as it’s a reward for the Kickstarter for that program. The idea being you can focus 100% on the material and not worry about the shape.

Blender, also an open source program, can be downloaded for free here:Īs well, the demo image for this time around has been modeled and rendered with blender: It’s not extremely important to understand how it really works, but it’s definitely fun to play with. Raytracers, unlike real-life, do a reverse, and start from the pixel on the screen and move towards the light sources, to determine what the colour of the pixel on the screen is. A raytracer is a type of 3d renderer, a method to visualise 3d models on your screen, which uses a model very similar to the real-life model of light, where photons come from a lightsource, and bounce off objects, with some ending up in your eye, so you end up seeing those objects. If we know about the basics of shadows and light, how can we use these to create believable materials?įor this tutorial, I will be using Blender’s raytracer 'Cycles’ to illustrate some basic lighting concepts. We refer to this quality of a drawing to describe materials as the ‘plasticity’ of the drawing(Which comes from the Latin word for 'moldable’). Okay, so this is the first of the two Krita kickstarter tutorials I am going to do, and this one focuses on an interesting topic: Materials.Īs we discovered in the shadows tutorial, the art of making a drawn item made of a recognisable material has everything to do with the use of shadows(and a little with the use of colour).
