Grate Walkway

what would you guys think would be the best way to make a grate walkway like the one in the pic below. I was thinkin about making a transparent shader but i dont know how to make one. I can make glass but i couldnt get it to make that type of grate. If you guys think that it would be best to make a transparent shader please help me make one. thanks.

You mean like cat-walk grating? Probably a transparent shader, but you may have to go through the sound tags to get the right one.

i think you just need too compile a bitmap in tool with explicit alpha. but you need too make a image with a alpha channel too do that. or you could just rip a grate bitmap and shader from someone elses map

Yea thats exactly what im looking for. I tried to do a glass transparent shader but it would never come out the way i wanted, i guess its because i dont fully understand how these alpha things work.

Glass would make it all clear. Look at the ladder texture. It has some parts clear and some not. Just make a texture similiar to the ladder but have it be a grate pattern. Then theres something with alpha's (I think white is clear or something) and that makes it transparent. I'm sure someone know's how to make transparent textures.

well i opened the ladder texture, and it doesnt really help me much at all. as far as i can tell its just a ladder on a black background. everything is already merged down so i really cant tell what they did. can someone inform me on making a transparent texture.

Alpha channels, and a few settings in the shader

the white in the alpha is visable, the black is invisible (alpha is differnt then the normal bitmap)

in the shader, its a lot of 1s, and a 360 lol

yea i finally figured it out, i got it the way i want it finally, ill prolly end up making a tutorial for this later on because of all the trouble i had getting this thing to work right. thanks for the help all.
