Hey,

Okay, so how would I go about making a perfect skybox render? (That is 6 different renders to put on the inside of a box).

It's for two purposes. First of all it's for use as an actual skybox for a plane animation I'm working on. Secondly it's for a reflectionmap as well.

I'm hoping there might be a plugin or something that can handle it for me.

Don't need a plugin for that :
make a free camera with 90 deg, FOV ... copy and rotate 90 degrees to the left , right , top ...etc and render ( this will give you the skybox images. THe image render must be a square example : 500x500 , 2000x2000 ...

Howdy !!

why not try and map your backdrop onto a sphere rather than a box ? you could be using Ps better yet HdrShop to deform a map into a panoramic one, then apply it with environement and spherical mapping on the sphere, and that should do ?

(ive heard about an alternative software to HdrShop being developped by students, can't recall the url though)

You could even use it simply as background image, without actual geometry to "support" it, and display that in your viewport for adjustements ?

Else, i guess you need a couple images, and stitch them together in a panoramic image, i know about a plugin called "PanoTools" for Ps that does that.

I would create a sphere at the center of the "world". Then add a reflect/refract map to it and render cubic map files to disk :)

I've made skyboxes for Half-Life before, which uses exactly what you mention, ie. 6 images. Set up a cam at world origin, set it to 90 degrees FOV, instance it out rotated 90 degrees each time, so you have six cams pointing to each side.

Make your environment as you want it, you can use all the geomtry and whatnot you wish.

Render out each cam.

If you want to get fancy you set up a video post sequence that renders out each cam to its own file. At the click of a button you have the skybox. It works very nicely.


er, I ought still have the file somewhere at home in some random backup.. in MAX3 format nodoubt. It's yours if you want it, PM me specifying transfer-details
