Animating textures

[ttyo888]

hi I want to know how to animate a texture in a way like say a character writing on paper.

[CmdCrunk]

You just use an AVI file that shows writing appear on paper as the the diffuse map instead of a bitmap.
And then the avi file syncs with the main timeline.
Hope that makes sense

Errr but the problem is how.... that's for writing on paper but what if I have animated the thing in the first place? like say a car which has skidded on the road...

oh i see what you mean, I wouldn't know how to do that, you might need to do some scripting or get a plugin such as ghost trails http://www.bytegeistsoftware.com/prod01.htm.

Ok
I can tell you a trick ( realy simple )
what you should do is to make the writing part by part in seprate textures , then apply the textures on piece by piece of the paper and set all materials to the opacity of 0 in frame 0
and active your animate and set your frame as your character hand moves and chande your opacity from 0 to 100
THats all
hope you got it
Cheers

Ok
I will show you this by some screen shots
I will do it today ( Hope Fully )

ok
Look
1_You first go to material editor as you see in first screen shot and you will have as much as you want materials with the some parts of your writing as textures in each and you set the opacity To ZERO in FRAME ZERO

2_ active auto key and set the frame number to the frame that you want to show that the character has write the first part which will be the first material ( first texture of the writing ) and set the Opacity to 100 ( do this to all of the materials but in diffrent frames that you want them to appear )


thats all
Hope you got it
Cheers
