How to add Colormap in Boom?

[1Destro3456]

I ask this question because I saw BOOMEDIT.wad and it had some real nice deep water effects. And I tried it myself, I think I know how to make it so that there is a texture at the top and the texture at the bottom, however I don't know how to add Colormap to the sector so that is actually looks like you're underwater.

Open BOOMEDIT.wad again and look at the linedef that controls the fake sector (i.e. deep water effect) for the sectors tagged 35 (linedef 182). You can see that the lower texture of this linedef is called BLUMAP, which is the colormap that controls the underwater effect. So, by applying a colormap as the lower (or upper) texture of the controlling linedef you get the effect to the lower (or upper) "fake" sector. The colormaps have to be included with the wad, between C_START and C_END markers.

 

You can find a more detailed explanation from the Boom reference guide, if you search for "242". But imo the best way to learn how to implement it is to look at how it's done practically, for which BOOMEDIT.wad is pretty much as good as it gets.

There is a set of boom editing tools on the idgames, you have to run it on dosbox though https://www.doomworld.com/idgames/themes/TeamTNT/boom/editutil

This solved it, thanks a lot!
