Camera.rendertocubemap has 4 overloads

(1) bool Rendertocubemap (Cubemap Cubemap)

BOOL Rendertocubemap (Cubemap cubemap,int facemask)

can be used to generate a scene static cube map in the editor. Facemask is a bitfield bit number that indicates that the cubic map surface should be rendered, and each bit pair

Should be on one side. The number of bits is the integer value of the Cubemapface enumeration. All of the default six cubic map polygons are rendered (the low 6 bits of the default value of 63 are open).

(2)bool Rendertocubemap (rendertexture cubemap)

bool Rendertocubemap (rendertexture cubemap,int facemask)

This is used for real-time reflection to cubic map rendering textures. This is very time consuming, especially when all six cubic map polygons are rendered in each frame.

If rendering fails this function will return false, some graphics cards do not support this function.

Also, be sure to Rendertexture.iscubemap = True
