Brand new to Lumion.  Just bought it tonight after a few days of playing with the free version.  Need a bit of help with some materials though.  I've read everything I can find on the forum, but I'm not sure what I'm doing wrong.  I'm just trying to use a simple chain link fence

If I use this attached texture in SketchUp and export the sketchup model to Lumion, it works fine.  If I try to create a custom material in Lumion using the same TGA file, it gives a black background instead of transparent.  Am I doing something wrong?

Convert your texture to PNG and remove your background. TGA as alpha is not yet supported.

Your TGA is OK to use as it has an alpha channel and v2.5 reads OK.  Just set the slider value for the Material Property - Reflection or Clip to 1.

The Reflection or Clip set to 1 was the problem.  Thanks for the help.  Really looking forward to working with the program and with the Lumion community.
