No, it does not have any gravity effect, the maximum it has is the light effect, but it gives me an error in the render since it cannot `process the subdivision of the lights, lower the subdivision to 1 and the resolution a little, adjust the use of 8 GB of RAM to the maximum and still the GPU could not process it ... and that is 2 GB of graphics card, I don't understand why I can't, you have your drivers installed and updated, this is already a bug in the rendering engine ...

With a 512MB card I used to work this well.
