In this way you can obtain really very good reflection effects. Here below you can see a sample.
On this image you can see the reflection of the grey environment + 2 white boxes + the fake reflection
Here we have the same scene with the same settings like above. Only the image for fake reflection is different.
Remember that with Mental Ray the fake reflection is NOT visible in the material slot as preview. You must make a test rendering to see the result.
There are many ways to create Chrome. Another way to create Chrome is trough a RAYTRACE material (change standard with RAYTRACE in a new material slot). But the result is the same as in the standard material.
A HDR image can also used as a fake reflection. HDRI renderings will be explained in other Florence Design Academy tutorials or lessons.
If you want exclude an object from reflection: go to the chrome material, select raytrace that you have in the reflection maps slot. Click on the button LOCAL EXCLUDE. Now just select the objects that must be excluded from the reflection of the chrome material. This will make the selected object invisible in the Chrome material.
A mirror material is very similar to Chrome: Black diffuse colour, no specular highlights and Raytrace 100% in the reflection map.
You can find the information for the illumination & render settings in other Florence Design Academy tutorials.
I hope you have enjoyed this tutorial.
