The answer lies in the Map properties in the Material Editor dialogue. You need to either make an alpha channel in the image that contains the area you want to be transparent, or make all area your want transparent a single, solid color. If the texture you are using has thousands of colors in it, you will be better using the alpha channel. In your case, I think you will be ok using just a solid color. I created a sample scene to show you how I did this. 
I applied the material we are about to make to the generic model (which would represent your metal panel in this case). The wall is just a default wall. I also have a Studio light set up just to give us a light source. When rendered without any modification, it looks like this. 
At this point, all materials are set as default. The image show is the generic model which we will be putting the material on. You can't see the wall right now, well, because the panel is casting a shadow on it... onward! Make a new material (Settings >> Materials) I am just using the existing Metal Panel material to cut down on time. Then go into the AccuRender properties. You can use an existing texture, but Revit doesn't like this, so I recommend just making a new one.  
Under the Maps tab, load up your texture map, adjust the pattern size accordingly and then and then go to the Map tab. Take note of these settings:  Let's say your pattern looks like this 
Mainly because that's what I'm using for this example) If you use the settings shown in the previous image, everything black will (hopefully) be masked as transparent and essentially cut through the component it is applied to. Hit ok until you're back to your model view, apply your material to the Metal Panel, radiate (IMPORTANT! If you do not radiate it may not calculate the shadows correctly!) then raytrace... let's see what happens! 
HOORAY FOR HOLES!!! Let me know if you have any questions. This was put together pretty quickly Edited on: Fri, Mar 30, 2007 at 2:55:45 PMEdited on: Fri, Mar 30, 2007 at 2:57:35 PMEdited on: Fri, Mar 30, 2007 at 3:12:12 PMEdited on: Fri, Mar 30, 2007 at 3:12:26 PM

You fell victim to one of the classic blunders. The most famous is never get involved in a land war in asia, but only slightly less well known is this! Never go in against a Sicilian when death is on the line! |

I also just found this: http://www.revitcity.com/tutorials/transparency_mapping/ In the tutorial section to see if I needed to submit this as a tutorial. So now you have two references :D

Hey, So I've been doing this, but 2 things... 1. If I just make a duplicate metal panel and choose the material with my map as the material of the metal panel's...I get a wierd "overlay" because I think it is mapping the image on the back too. 2. I tried to make the panel clear and "paint" the material (my transparent leafy skin) on one side, but the glass reflects... When you say "apply" is there a better way to do this that I am just forgeting????? it's been a long week! t

First question, what kind of element are you applying the material to? If you apply it to, let's say a wall with a material on each side, then you'll have two surfaces you'll have to apply the material to. Then the chances of the openings cut in the surface lining up are pretty slim so my tutorial assumed your metal panel that you were applying the texture to was just a single extruded element (as opposed to a wall). It should cut both sides if it's just a simple extrusion. I simply used the pain bucket to apply the material to my component in the tutorial. I started with the Default material, so I'm not sure if Revit actually applies the material as an overlay when you use the Paint Bucket. I always assumed it just replaced the material with a new one. :/
