Nolimits Question - Environment Problem

[A7]

I've been working on a new coaster called Projectile. I have run into a problem. I did not want to make a 3ds station because I don't really have much skill with 3ds. So, I decided to just modify the existing one with the environment file. I need the "railing", "wait railing", and the "wait gate" to be transparent or gone completely. I keep ending up with this though.

I have tried setting the texture of them to a completely transparent image, it didn't work. I've also tried these lines.

sim.stationrailing.texture.path=
sim.stationwaitrailing.texture.path=
sim.stationwaitgate.texture.path=

and this

sim.stationrailing.texture.visible=False
sim.stationwaitrailing.texture.visible=False
sim.stationwaitgate.texture.visible=False

and this

sim.stationrailing.visible=False
sim.stationwaitrailing.visible=False
sim.stationwaitgate.visible=False

No luck though. I'm starting to think it is not possible and their has to be something there.

By the way.. Still no rate on ROAR, or an actual comment about the coaster. Somewhat sad, and it almost seams forgotten.

If you keep the path information empty, no texture is being loaded and you see the default material, which is white. What you need to do is set a transparent texture. Just create a new tga which has a completely black alphachannel. Make sure to save with 32-bit in order to keep all 4 channels.

I think I made the image right. Still didn't work though. I'm using gimp. I create a new image sized 256x256. I select advanced options and then "fill with transparency". I now have this.

Then I go to layer, transparency, color to alpha, and chose black. Image still looks the same. I went to file, save as.

then I clicked save. It asked if I wanted RLE Compression. I unchecked the box. Their was another checkbox which I unchecked. It said origin at bottom left. Then, I changed the environment for the new image.
The new environment includes these lines.

sim.stationrailing.texture.path=Environments\Projectile\Transparent.tga
sim.stationwaitrailing.texture.path=Environments\Projectile\Transparent.tga
sim.stationwaitgate.texture.path=Environments\Projectile\Transparent.tga

Did I do something wrong? I feel like I did because I don't usually work with transparency.

Try this: make a new picture (16*16 should do) and fill it with black. then color to alpha, save as tga.
When you use that texture, the faces should either be transparent or at least black. If they stay white, the path information is probably wrong.
