In chapter 5 of the Blender part of the tutorials in The Bullet DVD, Andrew says that you need to make a matte from the bullet.
He does say some things about adjusting the color and make the black color from the bumpmap white. But how do i actually do it? I have tried thousands of things, but i'm a new guy at 3Dmodeling and i dont know how to do it.


Thanks for all the help. ;)

from Holland, Willem

When you set the beauty pass render, set the output to RGBA choose a file format that could carry alpha channel and you will have your matte to reuse in AE.

Too technical ? Doesn't help ? Wait the tut from Adobe167 ;)

OK, the exact words Andrew says: "And i also rendered out another object, i used the exact same bullet. The only difference is that i created a material that was red, and i had white for the black area..." [while he said this he showed me this picture:

Image ]

Then he said: "...and then inside of blender i set the material to shadeless, and that way it rendered it out without any of the settings, then we can use that when whe're compositing in AE."


So i rendered out a PNGsequence of a bullet, now i need a matte of it. So i need to use the same bullet only make the material red and the black area white. how? How do you set the black area white?

I think that you have to take the texture into Photoshop or AE and mess with some settings to get the texture to look like what AK showed us in the tutorial. Then you simply use that image as the texture for the bullet, and set the shading to shadeless. I think that button is in the lighting tab in Blender. Your final result should obviously have no shading, and should easily be used as a mat in AE. Does this help? I also did not exactly understand your question.

If you do mean the Blender background, it is in the world tab. But black is what AK used, do you want to change it?

no. i dont mean the World tab. just take a look at the whole picture, not only the thumbnail. you see the background is white as it should be... Andrew imported a picture which had black stripes on a white background. everybody who has seen TheBullet DVD should know what i mean. He called it a bumpmap, or NOR or whatever you needed to click on in Blender. Now, the black parts of the bumpmap needs to be white and the white part of the bumpmap needs to be red....
