Hi world,
I’m trying to make a simple skybox – I have a full 360 panorama that’s connected in 6 pieces to a Cubemap TOP (screenshot attached). I’ve been stabbing in the dark for a long time at how to properly attach this map to a material → geometry (or just the rear of a camera’s render). To be clear, I’m NOT looking to impose an environment map on a Phong MAT (as shown here: derivative.ca/wiki088/index … ubemap.tox), but rather I’m looking to create an always-visible background for my scene. As far as I can tell, there are no available examples / resources online demonstrating this; I’m hopeful there’s some relatively simple solution I’m missing here, just checking to learn what best practices are for implementing skyboxes in touch. Thank you!
My usual approach is to place a Geo COMP located at 0,0,0 containing a Sphere SOP. Set texturing of the Sphere SOP to equirectangular inside. Apply your skybox texture (Projection TOP can be useful here) with a Constant MAT to the Geo. Now place your Camera at 0,0,0 so it is inside the sphere.
there’s an example in the HTV Vive Development Environment

(look in the World COMP at the bottom, in there’s a Skybox COMP or something like that )

AHH! The Projection TOP was my missing key, and this HTC thread is awesome as well - @nettoyeur your answer made my day thanks so much!
You can also use a Box SOP with Cube Map coordinates on it. That avoids the Projection TOP and the loss of information you get from converting from Cube to Equirectangular
