Can someone tell me how to animate a light turning on and off?? seems stupid i know, but all ive learned is how to 'key' motion not how to key objects attributes.

PS. can you also tell me how to change textures in animation?

I'd imagine you could key the Intensity or Visibility, depending on what kind of effect you wanted.

How would i Key the intesity? i know that when you key motion you select your object and the type of manipulator. but, it doesnt seem to do anything when i select the object atribute and select 'key'. I know i must be doing something wrong then right? can someone walk me through this maybe?

In your Attribute Editor or in the Channel Box, right click on the Intensity attribute and you should see "Set Key" as one of the available options.

I believe so.... you can right click on almost anything in the Attribute Editor and Set Key for it.

nope you cannot directly apply this to textures. textures is not a keyable attribut. you can however use a blend color and key the blend value either through sdk or normal key.

and if you want to use the "s" key, you can open up your channel editor or something and make virtually everything keyable or remove normally keyable things from beeing keyed if you press "s".

I've found most of the attributes in textures ARE keyable....

what i meant is, the connections in a shader network cannot be changed interactively. through simple keyframing.

ah, I suppose that's true. One way to get around that is the Layered Shader... it's made to be able to key from one material to another.

that is only half true. it works with solid material real well. or if you want to combine differant kinds of shaders like: the highlight of a phong e + reflection of blinn + color of lambert.

but layered shader comes to its limit if you want to switch between a half transparent material and another half transparent material.
