Tommy L Posted December 29, 2007 Share Posted December 29, 2007 On the image attached I have a problem with the reflections bending. Specifically, the reflections on the marble island. Is this because I have the camera correction on? The table is flat and the material has no bump or anything like that, so why the curve, any ideas? Thanks, Tom.

STRAT Posted December 29, 2007 Share Posted December 29, 2007 it looks like the results of poor or meshsmoothed meshing, but i'm sure you've already tried that. is the table top a simple unsmooth 2 tri'd plane? does the reflection bend with any other camera? some ideas. try flat mirror refs instead of raytraced.

Tommy L Posted December 29, 2007 Author Share Posted December 29, 2007 Strat, Thanks for the quick response. The object is a simple chamfered box. The material is a vray mat with a falloff in the reflection channel and a bitmap in the diffuse. I really cant think what the problem would be. Ill just ignore it and hope it goes away I think. Still lots of other things to be getting on with..... Link to comment Share on other sites More sharing options...
manta Posted December 30, 2007 Share Posted December 30, 2007 try adding length and width segments... Link to comment Share on other sites More sharing options...
caffa Posted December 30, 2007 Share Posted December 30, 2007 It's a smooth problem, try with an autosmooth threshold of 0 and increase the segments of the fillet, so they look round. I really don't understand why the smooth affects the reflections, perhaps someone could explain it to us. Here's a little test to ilustrate: Link to comment Share on other sites More sharing options...
Glacierise Posted December 30, 2007 Share Posted December 30, 2007 It affects the reflections, because it bends polygon normals Link to comment Share on other sites More sharing options...

conjeo Posted January 7, 2008 Share Posted January 7, 2008 I love this thread. It shows that we are all still learning these in depth programs and even veterans ask for advice. I have not noticed this as well when I use chamfered boxes for countertops but I will now change that setting. Link to comment Share on other sites More sharing options...

alias_marks Posted January 7, 2008 Share Posted January 7, 2008 just as a side note (obviously not the solution to your problem) but I've noticed some strange things happening when i use normal cameras with camera correction modifiers in combination with vray materials. As an alternative I almost always use the vertical shift option with a vray camera to get around some of these strange behaviors. Link to comment Share on other sites More sharing options...
Koper Posted January 7, 2008 Share Posted January 7, 2008 i would have said its the 'falloff' type. but then again, i hardly use soothing groups, so don't know. very usefull info, we keep on learning thanx Link to comment Share on other sites More sharing options...
