industry standard normal buffers darktree shader

#1

Hello all,
I’ve just created a new darktree to enable you to generate industry standard normals buffers for compositing. If your compositor allows you to use your normals to add additional post lighting(and you’re on a PC) this is a must have. I’m not sure how accurate the z normal is, but it seemed to work fine in the test scenes. To generate the depth buffers add the material to a material effector and turn off all colour decals. Then use a boolean operation in your compositor to copy the red channel into the x normal, the green channel into the y normal and the blue channel into the z normal(tested in Digital Fusion).

If you didn’t understand a word I said then you don’t need this material. If you’re on a PC you need the free Simbiont plugin from www.darksim.com. If you’re on a mac, you need a pc(sorry guys)
Ciao

and here’s a very quick test of the buffers in action

“I don’t need maths” I said to the teacher, “I wanna be an artist!”

Oh how he must be laughing now…

If I got it right those effects are being done on the image in postprocessing in a compositing app, right? No rendering involved.

Cool.

yep, 1 still with matching normal buffers. All lighting and reflection done in Digital Fusion’s shader operator in realtime (25fps).
