Hi all
I’ve set the HB Shadow Calculation to PixelCounting

The .err file gives me this feedback labeled severe.

Hi @martin6,

This is happening because the instances that we use on Pollination do not have access to GPU. As a result EnergyPlus reverts back to its default shadow calculation method and that’s why you see those warnings.

We are aware of this issue. We need to find the best solution to use the instances with GPU when needed without adding too much to the cost.
