A Long Long Way to Go

River valley (Blender)

My first attempt at a landscape with river valley in Blender 2.8.

I’m pressing on with Blender, using the 2.8 beta, rather than the current 2.79 version. I figure that if I’m going to learn Blender, I might as well use the version that will be the current version when I get up to speed.

I’ll get to Blender in a minute but I’d just like to mention that I have a few writing ideas floating around in my head. I’ve completed one story and I’m mulling one story line in my head, but the characters want to do something that I’m not completely happy with. Yes, that is how it seems to me. I have little control over the characters and what they do!

The way that they want to act is within character, so I suppose I will put pen to paper, or rather, pound the keyboard, eventually. Sometime soon I’ll drop Blender for a while and switch over  to my word processor, but for now I’m still learning Blender.

Blender is complex because real life 3-D objects which artists are trying to draw are complex. For instance, in real life there is rarely a single source of light. We may say that a an object in a scene is lit by the sun, but really it is lit by the sun, by the ambient light from the sky and the surroundings, and by reflections from other objects in the scene.

The image above shows a studio set up for television, and it shows multiple sources of light and the stage on which the scene, whatever it is, is to be set. The stage is illuminated by a lamp, but there is also a shadow on it. The shadowed part can be seen because it is illuminated by other lamps. Things in the unlit areas around the stage can be seen dimly because some light is reflected from the stage or it spills over from other lamps.

Lighting is complex and one of the things that Blender does is emulate some of this complexity. When someone builds something in Blender the object that is modelled is colourless and textureless. It’s like one of those dressmaker dummies that is merely a shape and a framework for the clothes to be are created on it.

No materials

Some of the lighting has been set up for this object, but not enough. No materials have been applied.

The object in the above image is illuminated by a light source (or rather the object is drawn as if it is illuminated by a light source). It stands on nothing, is surrounded by grey, and is visually it is not that impressive.

For a number of reasons I recreated the tower and this time I gave it some colour by adding colour to the background and another light source, and some ambient lighting.

Cartoon tower

Cartoonish tower, with background, something to stand on and some ambient lighting. There is some other lighting, but it is a bit dim and hard to see.

That still looks cartoonish! It’s still decidedly unimpressive, but I am, I hope, making progress. I’ve learned a lot and hope to put some of it into practise soon. I’ve watched dozens of videos, some of which helped and some of which didn’t. Some of the people making the videos are very good. Others click rapidly on the various windows and menus, leaving me confused.

Some videos seem to refer to earlier versions of the software, which means I have to figure out some of the steps that the video creator just quickly clicked over. Some show how to do specific tasks, like create a floating island, or realistic landscapes, and I have to extract from those the techniques that I need. But I believe that I’m making progress. Maybe by 2020 or early 2021…

I forgot to mention that once the model has been built and been decorated with materials and  textures, it is finished but only exists as a Blender file. To produce images, like those above, the object needs to be rendered. The 3-D object needs to be converted to a 2-D image file. Rendering of complex Blender files can take hours as it is a complex mathematical task. The above images, and the one below that I am going to leave you with, took only a minute or less.

The last image is an early version of the river valley that I started this post with. Since then I have dialled back the ambient lighting and added some “materials” to colourise it. It’s probable that I will rebuild the river valley completely.

Please read my books. The paperback versions can be found Amazon, and the eBooks can be found there or at your favourite eBook store. Just search for my name, Cliff Pratt. I mainly write fantasy fiction.
