This is a very simple way to get a great looking office ceiling with realistic integrated lighting, without the pain of modelling. Everything is contained within the pre-made Vray materials and displacement is used to generate the lighting fixture geometry.
Choose from 4 variations: - Panel ceiling grid with grille reflector lighting - MF plasterboard ceiling with grille reflector lighting - Panel ceiling grid with curved reflector lighting - MF plasterboard ceiling with curved reflector lighting
Just apply to a plane object with UVW map set to 4.8×4.8m, apply the VrayDisplacementMod and hit render. Scene included with vray lights and materials/displacement applied.
