I’m trying to create a wall grazer light similar to the below using LED tape and a mirror surface arc as the reflector in 3DS/Corona. However, the light from the LED strip is being absorbed and not reflected. Is there a way to do this, or am I doing it incorrectly?
There are two issues here:
- This is an extremely hard to sample situation, and will cause a lot of noise. Basically you would like to get sharp reflective caustics, and Corona is not yet ready for this.
- Max sample intensity will clamp any samples brighter than the specified value (by default 20), so you will not get bright light reflected from surfaces. You can set MSI to a higher value (or to 0 to disable it completely and get no clamping), but again this will become very noisy.
