harrowboy Posted August 1, 2008 Share Posted August 1, 2008 hi people, I've been trying to use just a vray sun and physical cam to lit up this interior scene, but I get the problem of those black solid lines around the places where the sun light strikes. I have Gamma set to 2.2 Affect colors / Material Editors ticked Vray frame buffer Adaptive QMC / Catmull-Rom adp. QMC sampler: min 3 / max 6, thresh 0.005 GI: Irr. map and QMC both 1.0 Irradiance map: min -3 / max 0, HSph 70 and Interp 40 Environment: GI 1.0 Color mapping: HSV dark multiplier 2.0, 1.0, 1.0 (boxes unchecked) sun parameters: default cam setting: ISO 200 and 1/30s @ f8 would it be the position of my sun thats causing the problem?

dave013 Posted August 2, 2008 Share Posted August 2, 2008 Try turning on Sub-Pixel mapping in the Color mapping rollout. Link to comment Share on other sites More sharing options...
harrowboy Posted August 2, 2008 Author Share Posted August 2, 2008 thx Dave that did solve the problem; also would know if vray lights are needed for an interior scene like this? or do I just use the photometrics as if they were real light fixtures?

moodo Posted August 3, 2008 Share Posted August 3, 2008 try out with the hsv exponential turned off. i guess you dont need the hsv exponential, because you have an exposurecontrol with you vray camera. Link to comment Share on other sites More sharing options...
Squareframe Posted August 4, 2008 Share Posted August 4, 2008 photometric lights are the way to go...and they use less memory Link to comment Share on other sites More sharing options...
