<div class="IPBDescription">coplaner plane</div> Ok i have a triangle brush...originally made with a 4 sided cube...then i made it with a 3 sided cylinder, it is a perfect eqaulateril triangle that i am using for a light... why is it getting a coplanar plane error?

First of all WTH is a coplanar plane...!?

    You can check your ZHLZ (Zoner's Half-Life Tools) documents for explanation. But for now, I'm too lazy to go searching, here's a quote from the document.

    <!--QuoteBegin--></span><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>QUOTE</b> </td></tr><tr><td id='QUOTE'><!--QuoteEBegin-->brush with coplanar faces
    Example:
    Entity 10, Brush 0, Side 5: has a coplanar plane at (-753, -9, 251), texture CA1X_CON1B
    Entity 10, Brush 0, Side 6: has a coplanar plane at (-753, -32, 251), texture CA1X_CON1B

    This is always caused by vertex manipulation.<!--QuoteEnd--></td></tr></table><span class='postcolor'><!--QuoteEEnd-->

    i've run into things like this several times. sometimes when you carve something, it doesn't get the vertexes exactly on the grid, and actually makes two vertexes EXTREMELY close together, so that if you look at them from any place other than extremely closely you won't notice it. and when you try to select one of those two vertexes it will always select both. the only way i've found to get rid of them is by cutting the two vertexes off and then merging the two vertexes that were just created.

    i'm not sure if that's exactly what you're looking for, but i hope that helps.

    no...i didnt do any major vertex editing, i just took the three corners and snapped them to grid to make a equalateral triangle to make a light...much like in this picture here

    heres what mine says:

    Delete it. Then make another cube and use the clipping tool this time, instead of the vertex manip. tool to create your equil. triangle. That way you get the results without the potential of any problems.

    Clipping tool shortcut is Shift-X <!--emo&;)--><img src='http://www.unknownworlds.com/forums/html/emoticons/wink.gif' border='0' style='vertical-align:middle' alt='wink.gif'><!--endemo-->

    As for carving, it is the mapper's double-sided sword. It does make some things simpler but when you try to carve with a more complex object than the simple cube, it gets problems very often. Therefore, I don't advise using carve option at all. Better make it manually.

    Sorry for going off-topic like this... <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

    EDIT: As for making a triangle, simple. Just select the 'wedge' option and create a wedge. Tadaa, triangle. <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

    Ohhh... There's this very very simple way of doing the lights. Just as Tequila said, create a cube anc clip it, using the clipping tool. No problems with that. <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

    YES...ty for wedge idea...WEDGES WORK!!!

    But why cant i use a box or a 3 sided cylinder....?

    A 3-sided cylinder only confuses Hammer. Don't practise that. As for a box, as I and Tequila said, create a cube, then clip it.

    Sorry for double posting, but I couldn't attach the picture with editing my previous post. Here's clipping for you. Very basic, very easy.

    yeah i know how to clip <!--emo&:p--><img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif'><!--endemo-->
    thx anyway

    b/s wedges work fine! <!--emo&:D--><img src='http://www.unknownworlds.com/forums/html/emoticons/biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif'><!--endemo-->

    Well, I never used wedges much, just clipped the lights. But anyway, to everyone his own...

    And besides, no problem, I love to help if I can... <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

    Don't clip to create complex objects. It creates unnesesscary planes (or so I've heard). Use vertex manipulation instead.

    Also, a coplanar plane is when you have more than two vertices on one plane, as shown in the attatched image. Merging the vertices will fix that.

    A brush shaped with clip and a brush shaped with vertex manipulation should create the same number of planes, as long as they are equally complex.

    "complanar" means "in the same plane"
    "faces" are drawn on planes of infinite size.
    "complanar faces" are multiple faces sharing the same plane, HL does not like or auto-fix this because of the old fashioned way of calculating plane intersections.

    To fix the error create that purple line and enlarge the new "square" by mowing the new purple dots to the green dots.
    Warning: unstable VHE likes to crash on such kind of vertex manipulations more often, just save every step.
