Vera Visions Material Manual
5 Editor specific material instructions
These instructions only affect the texture when it is seen in the level editor. They should be grouped with the surface
parameters but ahead of them in sequence.
This keyword creates a material name in memory, but in the editor, it displays the TGA art image specified in qer_editorimage (in the example below this is textures/eerie/lavahell.tga).
The editor maps a texture using the size attributes of the TGA file used for the editor image. When that editor image represents a material, any texture used in any of the material stages will be scaled up or down to the dimensions of the editor image. If a 128x128 pixel image is used to represent the material in the editor, then a 256x256 image used in a later stage will be shrunk to fit.
Design Notes: The base_light and gothic_light materials contain numerous uses of this. It can be very useful for making different light styles (mostly to change the light brightnesses) without having to create a new piece of TGA art for each new material.

A brush marked with this instruction will not be affected by CSG subtract functions. It is especially useful for water and fog textures.
This parameter defines the percentage of transparency that a brush will have when seen in the editor (no effect on game
rendering a tall). It can have a positive value between 0 and 1. The higher the value, the less transparent the texture.
Example: qer_trans 0.2 means the brush is 20% opaque and nearly invisible.
