enviroment mapping..?

what are the best ways to go about doing thins in the BGE…

I’ve tried cube mapping… but rendering out your 6 views and then fixing the seams every time is too time consuming(plan on having quite few different sky bkrns here)… I have a panaramic image which would tile correctly for spherical mapping but only if it is mapped to an enviroment map…

Putting it on a low poly sphere makes seams in the texture (the amount of polygons needed for there to be no seam is just way to high to make that feasible)… is there no way of putting a spherical enviroment map in the bkrnd… (i.e. not attached to any geometry)…or is that not possible right now… how do other people solve this problem…?

Do I have to stick with fake cube maps attached to a cube… I suppose I could always hide the messed up texture seem for my sky sphere with more clouds or something…?

Have you looked in the graphics demos by snailrose for 2.41, one of those I think is environmental mapping.

I find if I use a square in the texture window and select all the points, flip it the way it needs to be with the keyboard r-90, etc. and then scale it just a tiny fraction down, the seams look O.K.

Here’s one method for a good box: Making a Seamless Skybox by Social

Don’t know about the a skydome, though. I tried once and didn’t have good success, so I just used Social’s method instead.

hi, thanks for the input everyone… I looked at GE graphics demos… you can us an enviroment map attached to an object… makes cool looking fake reflections… just can’t have an enviroment map attached to a camera (as far as i can tell?)… hmm i will tweek the mapping a bit to see if I can fix the seams…
