Camera Clipping Does Not Work in Perspective Mode

Hi. I can't use camera clipping when in perspective mode. I want to get renderings with twinmotion just like v-ray. I can add camera clipping in sketchup vray in perspective mode. However, in twinmotion. It is not possible to use camera clipping tool while I am in perspective mode. Is there any way to use clipping plane while I am in perspective mode? If not, How can i report this issue to the twinmotion development team? Thanks for your support.
