iamjaideep80 Posted August 2, 2008 Share Posted August 2, 2008 Hi...... When writing Mantra Vray Procedural, how to change the transparency ??? There is a "changeSetting" function available in Vray procedural, but don't know if there is any option for transparency. Don't know if it can be controlled through Vray procedural. Basically, I want to use it to implement LOD in mantra. As projection size will decrease, blending will happen over two detail models using Transparency. Is there any other method to do this???

iamjaideep80 Posted August 2, 2008 Author Share Posted August 2, 2008 Hi..... When I was browsing thru Rederman Docs, found that, there is a RiOpacity method available to control the opacity. What is the parallel method in Mantra??? Quote Link to comment Share on other sites More sharing options...
crunch Posted August 2, 2008 Share Posted August 2, 2008 Hi.....When I was browsing thru Rederman Docs, found that, there is a RiOpacity method available to control the opacity. What is the parallel method in Mantra??? The RiOpacity() call sets the initial value of Os. I don't think you can use transparency to implement blending. If you think about a stack of grids (i.e. more than one surface), you'll end up making the front surface transparent, showing the back surfaces. This is not the same as blending levels of detail. I don't think there's a way to do blending of LOD in mantra's architecture. Quote Link to comment Share on other sites More sharing options...
