is it possible to key a color and remove it in blender
Can you be more specific…?
Do you mean a color from the material of an object…?
If you do, then yes, select the object (with a material) go to the IPO window and from the menu on the header choose “Material” to see the keys for the material. The keys are called R, G and B (for red green and blue respectively)
If you mean key as in chroma key in compositing, it is most certainly possible with the node compositor.
Get a test build from www.graphicall.org, and see the sticky in Blender General questions about node compositing techniques.
It’s not so simpple as it is in, say AFX, it requires some tweaking.
yep…thats what i wanted…chroma key removal…thanks
