This is my first thread , so I want to say HELLO to everyone here.
I’m learning Blender for few months but I still don’t know many things.
Recently I discovered that I don’t have to duplicate objects for nice wire-frame rendering.
Maybe I missed something but I only saw tutorials with duplicating method.
I’ll try to describe my method and problem and expect that someone could answer:
is it official Blender feature or some bug in render engine.
If it’s non official , maybe it’s worth to correct and improve wire-frame feature.
If it’s official - some bug occurs. So let’s go.
I create object - sphere.
First material ( index 1 = Mat1) I set to wire-frame with Wire button then
in edit mode I create another material ( index 2 = Mat2) and assign to all faces.
After this Mat1 isn’t assigned to any face!!!
Mat2 is solid color without Wire option.
After rendering we’ll see something like picture on left.
And problem is: wire-frame is less visible on right-upper side of objects (from camera view) and it is light independent.
I tried different camera and light positions and I got always the same result.
It seems that wire-frame has offset toward left-lower corner of the screen and a little bit to camera and it’s right-upper side is covered by solid color of object ( Mat2).Always.
After that I turned on ZTransp option and set Zoffs to 0.06 on Mat1 to bring wire-frame closer to camera.
Now wire-frame looks much better but offset is still visible - a bit- picture on right.
Also now I can adjust strength of wire-frame effect by setting Alpha channel on Mat1.
Can anyone confirm and explain this behavior ??
I’ve tried this with different versions of Blender - from 2.45 to 2.48RC on WinXP and results are the same.
Blender files attached.
