Ugly light artifacts with KMarghrad202

[mikem]

How can I improve lighting in this scene? I am using knightmare's arghrad202 and tried -extra, -chop, -chopsky, -choplight, -chopcurve and so on. The light is caused by a sunlight.

Looks like it might be a bug with axis-manipulated textures (220 map format) and ArghRad. Somebody showed me a screenshot of that a few months ago, but couldn't reproduce it later.

Can you try removing any axis rotation on those surfaces?

I removed axis rotation but it doesn't work.

Well, it seems to have reduced the dark shadow problem noticeably.

Have you tried swapping in the original ArghRad 2.01? There were a number of bugs I fixed caused by compiling ArghRad with newer Visual Studio versions, as Argh compiled it with MSVC 4.0. I need to know if it's one of *those* bugs.

This is ArghRad201:

I have built a new room and there you can clearly see these light artifacts caused by KMarghrad202:




With arghrad300t9 there are no such light artifacts:




Are you already working on it because I really want to use your build tools.

I've been working on another test build of KMQ2 since the release of the last test build due to some bugs that were found.

I can put some time in on Arghrad, but I've already gone all through the source to find any logical cause of such glaring bugs. I have to assume that they are due to a change in the compiler used (Argh used the now ancient MSVC 4.0).

Have you tried to use zzsort's blarghrad (attached)? It was coded by decompiling Arghrad 300t, and I should be able to port it into my toolchain (with many hours of work).

I tested your blarghrad10x. These are the results:




light artifacts are gone:



but lightning is much darker and blurry:




This was built with your rad tool:

What compile parameters are you using? Are you specifying a -bounce or -scale value?

I'd like to see the .map (or maybe just the room that has the errors) so I can test compile it, and possibly try some code tweaks.
