This is on purpose. Refer to RTShaderSystem.cc::ApplyShadows. Changing this issue to a feature request.

I wonder if there's a nice way to make users aware of this limitation, maybe a warning we can print somewhere... Or always return false for Light::CastShadows according to the type, and also display it as false on the GUI...

Why is this on purpose? Is it a performance issue?

Hello everyone,

I'm working on some simulations where shadows from the lights are somehow important. Do you have any perspective to finish this enhancement soon?

Just let me know if you need some help.

Thanks!

In my case, directional light doesn’t cast shadow neither, maybe because I use Intel and AMD GPU. Is there any workaround? a plugin? I know Gazebo maintainer and developer are busy so I want to implement it myself, I just don’t know how.
