Hello, as we can read here:
after A7, we have a new Energy conservation mode: automatically it dims diffuse color as reflection is increased.
In short:
Energy conservation mode OFF: parallel object faces = brighter shader (old mode)— > Legacy mode ON because the old scene will not break.
Energy conservation mode ON: parallel object faces = darker shader → Legacy mode OFF
You can see in the Maru answer.
or in the Stan_Booth answer
When I load a shader created in Corona , I have the Legacy mode available, and it’s turned ON.
Then, I try to turn it OFF. I expected a darker version, to follow the Energy conservation mode. But, I have the exactly opposite image.
Then, I create a new material with the same properties, with v1.5. The Legacy mode isn’t available, and I have the same result with the old shader, with Legacy mode OFF…
(*) If I load a shader from 1.1.1, the Legacy mode is available. But, if I change Legacy ON or OFF, the rendering is the same.
(*) If I load a shader from 1.3, the Legacy mode isn’t available, and it’s turned OFF…
Again, with Legacy mode ON or OFF nothing changes…
I’m a little bit confused…
