I will explain with an example scene the problem i’m having!.
In the scene, i wish to create a golden disc with an image of a tree on it!.
Like this, without bump… http://img803.imageshack.us/img803/3329/treewithoutbump.png
Here again with Bump set to -0.1…http://img803.imageshack.us/img803/3452/treewithbump.png
And here, the image of the tree i used, it has an alpha channel background!..http://img691.imageshack.us/img691/3151/trees00581s.png
Both look ok but as you can see, the tree has taken on some of the golden material?..
To create this, after modeling the disc and texturing the ground plane, I set up the materials for the Disc!.
First, the golden colour with receive transparent shadows!.
Then, i add a texture, the tree!.
Other than adding the bump in one of the pictures, all else stayed as was!.
What i would like to have is the gold disc with it’s material but the tree, being more of a mat say!..Maybe the spec reacting in a different way and not having the golden colour or reflection e.t.c!.
I find if i tick the alpha defuse in the influence panel under textures and set the transparency in the materials tab to zero, i get this!.. http://img706.imageshack.us/img706/519/treetranstparentoff.png
So, i thought maybe i should add another material but on rendering, there was only the floor and the disc, not tree texture no matter what setting i changed?..
Please help as i’m sure there is something i’m doing wrong or forgetting!.
