High Res Camera Projection -> Texture Baking

[Catpowerz2001]

Hope this is as easy as I think it should be!
Want to re-create this CamProj trick.
Figured I'd
1 - find image
2 - project it onto 3 planes using prosumer camera settings (<35mm sensor, roughly 28mm lens) so it matched what people would take the picture with
3 - bake textures for each plane into 3 images
4 - print textures and apply to real world corner (we have big printers)

I'm comfortable with camera projection in Nuke, just wondering if there is an easy way to bake textures in Nuke. If you know how could you please give me detailed instructions. (I'm assuming Nuke can handle 5k projections and the high res texture baking I need)


Thanks for any help - Chris

set your scanline renderer to "projection mode" "uv" mode and it will render the unwrapped texture

YUP! Hook a scanline up to each geometry, switch to UV, write it out, works like a charm. THANKS!

A note for those using more complex geo.. (Not in your case with using cards Catpower2001)
watch out with this technique, it doesn't quite wrap around more complex geo and can leave thin seams blank at the edges of the UV coordinates. It's happened a few times to me in the past. (Not sure if the issue's been fixed in later versions of nuke.

Happened to me as well.
