I had a feeling that I'd asked about this before but I can't find the post. If it is a repeat, please forgive my faulty memory.

Would it be possible to extend the sidedef brightness feature so that the value could be set independently on all three areas of a line?

At present, sidedef brightness affects the whole side. Therefore if you have, say, a step with LIGHT3 on its face, but a regular texture on the uppser surface of the same line and want to set LIGHT3 to have a higher brightness than ambient for that sector, the upper would also be bright:



Of course, there are many more situations where this would be useful and there are editing ways around many of them but I feel this would be useful.

So, possible? Is it within UDMF specs?

I believe this open pull request adds the feature you're asking for?

I think Rachael is trying to go through and get some of these merged lately, so fingers crossed this one makes the cut.

That does indeed look like it is for adding the feature. Thanks for linking to it.

You can make lights as separate linedefs.

Indeed you can.

I did say that there are many situations where this feature might be useful though (not just something like I pictured) and that there are also editing ways around most situations. However, these editing effects often mean a bit of compromise or slightly clumsy handling of narrow lines/thin sectors/architecture not lining up quite how you want etc etc so the feature would be useful, and often better than many of the mapping workarounds.

Looks like it got merged! df976e2 Add per-tier sidedef light levels to UDMF maps

Excellent news. Thanks to those involved in writing it and including it.
