Render reflections to texture in 3dsmax?

I know how to render the raytraces lights to a lightmap texture in 3dsmax (3dsmax is the best lightmapper, btw, it makes 100% realistic lightmaps which look WONDERFUL and it's easy, and makes you only need ONE editor :D), but how can I render a spherical reflection map to texture? When I use the ordinary Render button to render from perspective, it looks fine, and the reflection looks fine, but when I press Render to Texture, select the object that reflects, selects CompleteMap, and press Render, it doesn't generate the reflection map, but just renders as it didn't have a reflection. How can I solve this?

I don't think you can 'bake' reflections, because they're relative to the position of the camera.

Ok, then I thought about an another way to do it. Is it possible to generate a Blitz Spherical reflection texture in 3dsmax (3dsmax renders the area around 360 degrees it into one picture from the cameras perspective). Just spheremap.bmp in mak's Teapot sample. If it's possible, how? I don't wanna use cubemapping for static reflections, and reflections from a large ground.

I don't use Max, but Maya offers options for most maps or pre-rendered stuff to be exported when rendering.

You'd want to render a 180 shot, not 360, since spherical environment mapping doesn't rotate around to the back of an object. You can generate such an image by adjusting the lens/zoom of your camera. Note that you don't need the image to be all spherical looking like a lot of spherical reflection maps look; anything outside a central circle is just ignored so it doesn't matter.

there is a cubic environment reflection 'render to texture' feature that has been in max for ages, I could tell u how to do it if u need to, as for spherical map, i think theres something called fish eye or something like that.

TigerZ: Please tell me :). I will use cubemapping for small dynamic surfaces, and spherical maps for static/huge surfaces.
