Originally the texture files were TIFFs. TIFFs, as you know, can carry their own Alpha and Color Channel. Some of them I have are like that and others have a seperate Alpha and Color. After failed attemps I converted the Textures to Bitmaps and JPGs and created my own Alphas on those that did not have one. The odd thing to me is that the objects and textures work perfect in Bryce, Vue and Terragen 2. Although they have to be manually loaded in Terragen 2, but after that they look great.
All I have done is to add the Color Texture in the Color slot and the Alpha Transparency in the Alpha slot. If there is another way to go about doing this, please tell me and maybe showing me your shader tree might work along with a brief explanation.
Thanks.......
