How to do edge renders in Lightwave 3d, a brief tutorial

This is a short blog post, which will describe how I go about edge renders in Lightwave 3d. It’s really easy and I find it a great technique for renders that are not photorealistic.

I am using Lightwave version 11.6, I’m not sure how this works in other versions. But it’s probably almost identical.

What do I mean by edge renders?

This is an effect that runs a line along various edges and boundaries. It can be used to emphasise fine detail, or to give a diagram effect. It works with transparency, and animates nicely.

Here’s an example.

Note how features of the telescope are highlighted with fine white lines.

The Saturn 1B model, Follow along with the build.

I gather from Twitter that some people find it interesting to follow my approach and progress when building a new model. So here’s a blog post where I will show how a project comes together, with lots of illustrations.

My starting point is to gather references, particularly high resolution photos, and plans with dimensions. Fortunately this one is covered in the excellent “Rockets of the World” by Peter Alway. It’s not highly detailed, but I find if you can get the overall dimensions of major features correct, then it’s not too tricky to fill in the rest from good photographs.

Tutorial: Importing Blender 3d content into Lightwave or Vue

One of the frustrations of working with CGI is that you sometimes find a brilliant free model, but it’s not for your software. And a specific example that has frustrated me is that there are some great models available in Blender format on the NASA 3d object library site:

Now, whilst I have heard of Blender, I’ve never tried to use it, and 3d packages can be very difficult to learn. But I decided to give it a go. Maybe I’d be lucky! Continue reading “Tutorial: Importing Blender 3d content into Lightwave or Vue”

Making a dwarf planet – Tutorial

I wanted to make a dwarf planet, using elevation maps from the Moon, (and maybe Mars?) for realistic craters. I thought it may be helpful to save out the steps, so that others can follow along. Tutorial time!

You will need:

  • The 3D program of your choice, it should support displacement maps.
  • A high res source elevation map, these are available online.
  • An image editor that can edit 16 bit grey scale images.

Getting started

I started with a slice of elevation map from the rear of the moon, (less recognisable), in the proportions of 2:1

This will have seams at the left and right edges. To fix this we need to first use an offset filter, with wrap, to move the whole thing 50% to the right. Continue reading “Making a dwarf planet – Tutorial”
