Spring RTS Engine

Hola,
i would like to know how i can do emit texture.
I need to "self-illuminating" some parts of an object for example the neon or other parts.
How can I do this?

thx

Manually. afaik Spring can't cast light from textures, and it certainly wouldn't 'glow'.

s3o textured units can have a sort of glow on them.



hard to see, but the blue part of the engines have a bit of glow to them, but its not like a dynamic light or anything.

yes it's ok!
how can you do this??
manually ? painting the texture with a light color + gaussian effect??
i did this:


But i would do this

you use the red channel from texture2 to control the self-illumination.



from http://springrts.com/wiki/Units:Textures :
"Red values are glow. The more red in a given pixel, the more glow it will have, overriding the light levels in a scene. A white Texture1 pixel with a totally red Texture2 pixel will always be completely white, no matter what."

someone write us up a glow shader

can you learn me how create the red alpha channel please?
so for the texture 1 i use DXTbmp to make texture + alpha ( for colors)
i tryed to use DXTbmp for texture 2 but don't work...
what do you use?

its not a red alpha channel.

on the second texture the green channel is reflectivity, and red is glow. so if you want the blue bits on your rocko to glow, black out everything except the blue bits, then colour them in red.

Like this?:

yes

As you said, adding a little gaussian blur will make the effect nicer.
