I'm trying to create space bacground with all kinds of objects. Different kinds of stars with textured background and lens flares, nebulae with images and hypervoxels, i even plan to use polygonal objects for planets, big space stations, suns, etc...
All these things together take long time to render and i simply don't want them in a scene. How to setup camera properly to bake them in all directions into image then reapply this image seamlessly and without visible stretching?

Rendering a square image in 90o every direction and applying it to a flipped face cube works best.
To do this set the camera FOV to 90o and the aspect to 1 then render 90o in each direction. Obviously set the frame to be square say 2000 x 2000 or whatever resolution will be sufficient for you.
Map it onto the cube using planar UV's. Set the luminosity on each surface (1 per face) to 100% and turn all other surface atributes down to 0%.

I hope that makes enough sense othewise I can elaborate a bit, let me know.

Thanks Sammael! Thing with cube really works best.

Sensei, great tools! Especially RasyRetopology, on video looks much faster than such thing in ZBrush.

Sensei, great tools!

Mine the best modeling tool is EasySpline http://www.easyspline.com (it's taking a lot of time to see all videos; the shortest description EasySpline is yet another sub-patching algorithm, which is using splines as patch edges, and 20+ tools to edit splines), 2nd one is EasyMesh http://easymesh.trueart.pl (all-tool-in-one).
