Does Darkplaces have reflections?

[Mexicouger]

Does Darkplaces have real reflections of any kinds? Like setting a material to be able to reflect the environment or other entities? If so, How can it be done?

[leileilol]

Yes, and it's applied with commands in texture shader stages (scripts/blah.shader).

Hello Mexicouger,

There are basically 2 different ways to bring reflections into Darkplaces:

1.) dpreflectcube shader
2.) dp_reflect shader

to 1.)
Pros:
- You can make single areas in one texture reflective.
- You dont need r_water enabled
- Works on world textures AND model textures
- As good as no performance impact
Cons:
- The reflection is only what the cubemap shows (NOT live/realtime; not a mirror)

to 2.)
Pros:
- The reflection is LIVE/Realtime ! That is why you see yourself or any other entity in it.
Cons:
- You cannot make single area of a texture reflective (only complete texture)
- You need r_water enabled
- Impacts performance (relatively to size of mirror)
- Works only on world textures (no models)

Please read the dpwiki (now backedup on chip´s homepage) to read more details about these 2 shaders keywords:

I uploaded the files + shaders that were used in youtube clip no.1. So you can see an example how it is done.
There are also more links in its readme.txt to more examples:

Thanks for your so helpful post Seven. It really helped!
In the shader for dpreflect, what does each parameter do? I failed to find documentation of each parameter.

Thank you Again Seven. I fail to find documentation on dp_refract and dp_water as well. Mind explaining them a bit?

Thank you very much Seven. I now have a good understanding of this concept!
