spherical texture projection

Postby leclaire » Sun Dec 17, 2017 5:43 pm

I'm playing around with spherical maps and projecting them on geometry, in this case a 180 degree curved screen. I'm able to map the texture properly with a texture SOP but I'm struggling to find a way to 'retrieve' the texture from the geometry and lay it flat for output. I've attached a sample file, basically I'm trying to get the texture seen on the 'screen' inside the geo COMP.

For those of you familiar with d3 or 'disguise' I'm essentially looking for the same functionality of the spherical texture mapping method.

link to sample file: https://www.dropbox.com/s/3ij7kcgytvhfvtt/spherical_question.zip?dl=0

Is this possible or should I take a different approach? Thanks!

Check out my posts and RFE for a uv map render mode. I’ve also posted steps to recreate it.

Slightly easier (in your case, with a regular object) is to start from a map that you know you can render to and texture the object to fit.

PS please plus 1 on my RFE so Deeivative can see it’s needed.
