Quake3World

I was messing around with water shading this weekend and documented it here: https://www.ferdinandlist.de/blog/idtec ... r_shading/
I was mostly reproducing existing knowledge but maybe it is useful for someone!

If anyone has any additional tips and tricks around water and fog, please shoot!

I updated the post to try some tips I got from quBit regarding envmaps on tesselated deformed meshes. Find the things at the bottom of the post! (videos included)

Oi, cityy! You're still alive! Nice work on the water shading. It's pretty amazing that 20+ years later, people are still finding ways to make the game prettier.

Heyo, alive and kicking, trying at least.

Not to leave a wrong impression here, this post merely collects existing knowledge. I know Hipshot has been blending water for ages. quBit's idea to put stuff on a mesh.

I'm hoping to make more samples like this one in the future.

I fixed a shader warning in Quake 3 related to deformVertexes normal that would cause shaders appear like they were missing. Wrote a small note about it here: https://www.ferdinandlist.de/blog/idtec ... es_normal/

The robot renegade shader manual apparently lists parameters for deformVertexes normal as for deformVertexes wave.

But looking to the source code, this is interesting: I would like to know what that thing does.

Try making the water less transparent and a closer fade to the edge?

I remember trying to put a video to the water shader. But only works with that engine (ZEQ2-Lite last SVN revision):
