How to render detailed terrains in Poser (Part 2)

Description

This is the continuation of the first part of the tutorial.

The image shows the settings for the material. The important parts are:
  1. the image is configured with a custom gamma value of one (it does not contain color information but RGB encoded values of the normal vector components)
  2. the image map settings texture coordinates is set to UV and the Filtering mode to crisp
  3. the image map is connected to the Gradient_Bump slot (you should tune appropriately the intensity, the value shown is just an example)
  4. the gradient mode must be Normal Map (tangent space)

All the rest of the material can be configured as you prefer.

As you can see, the whole process is not difficult at all and allows you to render (apprently) highly detailed terrains without taxing Poser.

Hi !

There is a real-neat short-cut when an impracticably mega-poly terrain has a bundled 'height map' or 'draped' texture map. Use the former directly or latter gray-scaled as displacement map on a low-poly base-plane.


Some 'gotchas'...

Bump & displacement mapping do not apply until scene is rendered, and getting the vertical scaling right is *hard*. Trying to match horizontal scale is non-trivial. Much iteration required to adjust Y-offset etc.

I would really, really like an FX plug-in for Irfan View that does contouring / posterizing, can turn a sand-pile's map to a layer-cake or 'bread & butter' model...
