  • problem with photon map/irrid

    Hey Everyone

    Workinh on an internal animation sequence using large vray lights to light the typical open plan office structures. I have encountered many problems with this job 1 The model 110mb takes forever to load 30mins but merges in a min. 2 When i calculated a photon map save it i then have vray convert it to irridiance and render all i get is white out. if i turn the gbuffer(exponetial) down to 0.001 it renders almost correctly but washed out. There are about 25 vray lights in the scene. This is perplexing to say the least. Help please anyone

      The smallest one is about 500mm by 500mm with subdivs set to 3. In the light settings under system it is set to 150 on diffuse subdivs and multi of 1. If i can go to 300 diff subdivs anything higher will crash max. I will post some screen grabs. If i render with just irridiance it is fine but takes a while with some high settings to get rid of artifacts. eg -3/2
