tayrona Posted July 25, 2007 Share Posted July 25, 2007 Hi everybody, I am working on an exterior animation with semi-open spaces... I am using max 9 and vray 150. (imap + qmc) I set lighting as always I do: HDRI for environment skylight and a IES Sun with vray shadows... my trouble now is that semi-open spaces are very dark inside... I dont want to add a lot of lights everywhere.... and I dont want an ambient light to make everything to look flat...... I attach an image and my sun settings........ any trick available???? thanx!

mfured20 Posted July 25, 2007 Share Posted July 25, 2007 your rendering does look really dark... are you using any gamma correction? you could just try to up the gamma correction in the color mapping rollout in the vray render dialog. Link to comment Share on other sites More sharing options...
RTurner Posted July 25, 2007 Share Posted July 25, 2007 What areas are you concerned with, the underside of the volumes on the left or the objects in the distance? Its hard to tell whats going on here....but I notice that the "floor" material on the left is dark, this will not bounce much light into your interiors. Also your area shadows are very "hard" which "naturaly" indicates strong direct light, few clouds, which will give you very contrasty images, and dark interiors. make sure your HDRI image and your main light source are in agreement........soft shadow/clouds , hard shadows/clear sky. You can also bump up your secondary bounces. Link to comment Share on other sites More sharing options...
tayrona Posted July 25, 2007 Author Share Posted July 25, 2007 ok thanks for help, but please be patient with this "low english level" girl.... explain better... bump up secoundary bounces.... Link to comment Share on other sites More sharing options...
RTurner Posted July 26, 2007 Share Posted July 26, 2007 There is a multiplier next to the GI engine options, under the indirect illumination tab. Increase the seconadary bounces, this will make anything not illuminated directly by skylight brighter. A better way would add a few lights in the interior spaces so you keep good contrast in the shadow areas. Link to comment Share on other sites More sharing options...

Geoffc Posted July 30, 2007 Share Posted July 30, 2007 If you're using an HDR for your environment background, render to EXR format, open in photoshop, and go to the Exposure settings. With those settings, you can really brighten up and bring life to an image. Link to comment Share on other sites More sharing options...
