I hope this isn't a useless thread, just thought it would be constructive to let everyone know about it. I was looking up some TDM related concerns, and accidentally stumbled across another fork of the idTech4 engine. It's called fhDOOM, and it seems to have a lot of neat graphical improvements over the stock engine. eXistence/fhDOOM There are definitely things in there that TDM could consider grabbing! Some important ones highlighted on their front page: Modern renderer based on OpenGL 3.3 core profile. Any up-to-date engine should have this as a norm.Parallax mapping. Not sure if we have this already... I only know the original engine had simple bump mapping.Soft shadows. A heavily desired and long awaited feature.Alpha textures affecting shadows. This allows light to shine through textured grates, which is a very beautiful improvement.Soft particles. This one we already have now however.An example of the old lighting system (ours) versus lighting with shadow mapping (fhDOOM): As the obstacle to new features is almost always finding someone willing to code them, discovering those improvements for our engine is a goldmine... since unless they conflict with any of our changes, I assume they should be easy to just plug into the code. Can any of this good stuff please be considered for inclusion in TDM's version of the engine?

I was looking at some images we have posted after taking some time away from computers entirely for quite an extended period of time and there's one thing I noticed. When we have specific brick or cobblestone textures they look fairly flat and bland. Maybe we should revisit the idea of parallax mapping, it would really improve these textures and actually increase performance because mappers wont need to use polygons to make convincingly 3d cobblestone and brickwork. We don't need parallax for all textures, this is one of the things TDS did right. Some textures had parallax some didn't, why don't we do the same, is this a good or bad idea?
