Swapping lit/unlit gauge polys - Bill?

Recommended Posts

I've been trying to implement the technique of swapping out lit/unlit gauge polys for analog gauge lighting, but something is elluding me in the process. I assume since the lit $texture has an associated _L, that in order to REMOVE the backlighting for a copy, one must apply a new material based on a copy of $texture and omit the Self-Illumination property.The only problem is I can't get it to work that way! It remains lit (although the swapping XML .mdl code works fine). It's just ignoring the self-illumination attribute on the new material.Perhaps I'm going about it all wrong, but short of adding a copy of the gauge to my $texture (seems a waste), or adding a new VC section (an even larger waste), this seems like it should be the correct way to do it. What am I missing here?Thanks,--Jon

Since you are using a "clone" of the original, the original's UVW mapping is also cloned, so that is ALL you need to do! ;)Of course you do need to set up the hiearchy in the model appropriately, as well as provide the XML condition based on the panel lights variable (or whatever custom switching you might want).interior....panel_not_lighted........(all gauge polys go here with no Self-Illumination _L.bmp in the Material)....panel_lighted........(all gauge polys go here with Self-Illumination _L.bmp in the Material)Obviously, once you've mastered this, if you are modeling a complex aircraft panel that has multiple, independently controlled lighting switches, you can expand this concept by using custom L:vars to control the gauge backlighting.Also, don't forget that you need to account for more than just the light switches... it would look silly to have the panel lighted up with the battery turned off and ground power disconnected... ;)

Thanks Bill, I'll try that. From your description, it seems the only difference is that you would create a new material, where I had copied the original material and then un-checked "Self-Illumination". Perhaps some strange quirk (as if that'd be surprising:)Also, I will check my hierarchy as I certainly haven't been proactive in making sure it's intact during construction.The lighting is certainly very frustrating, and "hack" feeling, and I'm sure many many people are grateful for the ground you've broken (and shared) in helping us overcome these design flaws. Here's an image of what I've been up to...Thanks again,--Jonhttp://forums.avsim.net/user_files/146342.jpg

I've been oogling that pic for a few days now and all I can say is HOLY COW!Jon, that's one VC that will change the standard for all others that follow in the future. Truly amazing work.Scott / Vorlin

Oh, thanks so much Scott (and Bill). I haven't released many pics of the project over the last 3 years, but it's certainly been tempting:) I hope to have much more material available later this year as it approaches completion.I just want to say that none of it would have been possible without this forum and the many helpful people who contribute here.--Jon
