Dag Posted December 4, 2023 Share Posted December 4, 2023 Hi, I have a little problem with my glass material. When I set the IOR to the correct value of 1.4-1.5 the rendered result looks like I had a magnifying glass. In other DCC it looks correct. What should I do for get a glass with correct look and correct IOR? Quote Link to comment Share on other sites More sharing options...
Atom Posted December 4, 2023 Share Posted December 4, 2023 I also noticed the Karma IOR values no longer match the traditional IOR charts for materials that have been referenced for decades. Just lower the IOR until it looks good. Or don't use glass at all and just use transparency. Quote Link to comment Share on other sites More sharing options...
Dag Posted December 4, 2023 Author Share Posted December 4, 2023 I use it as workaround for glass surfaces set IOR to 1 and it looks better but on the other hand when it is needed it got to fail. Thank you for your response, so I do not feel dumb as I tough it is my fault Quote Link to comment Share on other sites More sharing options...
tamagochy Posted December 4, 2023 Share Posted December 4, 2023 Do you have thicknes on the glass or its a single side poly? Quote Link to comment Share on other sites More sharing options...
Dag Posted December 5, 2023 Author Share Posted December 5, 2023 This is just a single sided mesh. Quote Link to comment Share on other sites More sharing options...
atyspmrfa Posted December 5, 2023 Share Posted December 5, 2023 I think you did quite well. If the IOR lower is defective, you can replace the glass with transparency and it will look fine. Quote Link to comment Share on other sites More sharing options...
tamagochy Posted December 5, 2023 Share Posted December 5, 2023 With single side mesh IOR should be 1, or you need to use thin film refraction Quote Link to comment Share on other sites More sharing options...
Dag Posted December 5, 2023 Author Share Posted December 5, 2023 (edited) Thank you for the hint. What is reasonable thickness for window glass? I pushed it up to 50 to see also reflections in the windows. Edited December 5, 2023 by Dag Quote Link to comment Share on other sites More sharing options...
