r505 reflective floor problems.

[Enjay]

This affects every reflective floor that I have checked but I know you have a copy of my Burghead mod so this is from map113 at approximately coords 2200, 300. These screenshots are from the slightly updated version in the archives (updated back in January/February I think). In each case, the shot is what r505 looks like followed by what it should look like.

[spoiler]Odd beige effect



changes as you move around the reflective surface



The lower side texture seems to be repeated above the table surface



A reflection in the shiny surface appears to have a z-fighting-like effect (just visible below the cacoward model).

I have to admit that I'm puzzled about this glitch. Apparently the clipping plane I try to set here does not work. I'm quite sure that this same code was properly working on older drivers/hardware.

Sadly, the information about this feature is rather slim so I can't even confirm if the values I set are correct...

If it helps at all, r471 does not show the problem but r478 does. These are the only builds from that time that I still have handy but I'm re-downloading r473 and r475 to check them.

[edit] OK neither 473 nor 475 show this effect so it appeared after 475 and is present in 478. [/edit]

Here's what I found out:

If I switch shaders off it looks correct
If I switch shaders on it's totally broken

This looks like a driver bug.

And since it's the second thread about this issue I'm closing it.
