guys, I rendered just a scratch scene with a cube, there is no problem. But with a render of my built scene, there is not possible to gain any render. I tried default setting... but still not working. what is my scene about? There is a suburb with perhaps 20 buildings made with GIS just low poly boxy ones and in the center, there is a small garden parcel with green grass and one tree. The whole scene is white with the HDR surrounding only grass is colored and the tree textured. To have leaned grass I used a wind. Do you have any ideas about whats going on? Thank you.
