Hey guys I am having a problem with vray rendering a particular part of a scene in an enclosed area on the side of the building in the scene the render times sky rocket from about 20 mins to 4 -5 hours and even then it crashes midway through. I have attached my settings and a screen shot of the view port to see if this can help out. I also rendered other parts of this building from the front view and render times were only 10 - 20 minutes long.
Everything in the view port pic besides the objects in white has a displacement map on it with “tight bounds off” and “keep continuity” on. There are also 2 Vray lights in the scene and both of them have there sub divisions set to 12. When I reduced the subdivisions it make no difference in the render time. Please help me out.
