i need to create a reflection on an object.
From what i found till now, i can create reflections on objects using cubemaps, but that reflection is static. How can i create a reflection for an object that is a live reflection of things in my world? i.e. if i move a body, i would like to see the reflection of the body moving.
For this “live” reflection, is there any chance of working on mobile? (iphone 4)
You can render to a cubemap but this is quite expensive (and requires the pro version). Most of the time, you don’t need to render the six faces (for convex volume, only three faces are required at any time).
One good practice to reduce the performance drop is to render the cubemap at a lower resolution and with a short farClipPlane.
You can also play with the layer mask to render only some objects and not the whole scene.
Use MadFingers Environment Cube map shader, can be found here -
