Transparent gifs

[benrickel]

Hi there Maya community.
I have tried the following in creating a wiremesh (both polygon and nurbs).
I have created a transparent gif when i assign it to the nurbs and poly surface it indeed works. i have mapped the gif to the colour as well as bump channel. it works fantastic. but when i render the scene the objects become opaque.
pls help me.

Make sure that the default color of the shader is set to white - the default setting for this channel is a 50% gray, which will give you opacity. If that isn't it, have you tried using a different file type for your image? Perhaps there's something about a GIF - try a TIFF or TGA.

Hi perseus2
thanx for your reply.
You see the thing is that when i map the transparent gif to the colour channel it works perfect and indeed i get a good preveiw in the pers window. But when i render it it gets opaque.

Is it that i have to mapp the file to the bump channel as well. or do i need to hardware render it.
pls advise...

what i want in general is a polygon having a textured gif mapped to it so that i get the effectof a wired boundary around a house.
thanx

There is a wireframe shader here at highend3d that may do what you want without any fancy texture mapping. BTW gif is not the typoical file format you'd want to use as a texture map. Try Tif,SGI,Maya iff etc or other formats that are 24bit color at least.

Have you tried searching highend3d?

Hi folks thanx for all ur help...
I have succedded atlast.
u see what has to be done is that create a texture having only black and white colour , map it to the transparency channel and invert it.
Now what it does is that as a thmb rule the black part is made transparent and the white part opaque so in the end u get the effect of a wire mesh.

I found it very useful and handy as u dont have to do much apart from it and u can use any file format for that.
