Michael J. Brown Posted February 4, 2008 Share Posted February 4, 2008 I've been getting some pretty extreme color bursts and artifacts on and around any objects with raytraced reflection when rendering with Mental Ray within Max 2008 (standard materials). (most apparent on orange Ford Edge in image) Even with the reflection values set to "1", artifacts persist. I end up having to change the materials to A+D. Is there a way around this? Is there a way for me to keep my raytrace reflection mapping on my standard materials without picking up these crazy side-effects? Link to comment Share on other sites More sharing options...
Justin Hunt Posted February 4, 2008 Share Posted February 4, 2008 Why do you want to keep using the standard material? Raytrace refections have been a problem for a long time (way back to version 7) Use the A&D its gives faster, cleaner refections and a hell of alot more JHV Link to comment Share on other sites More sharing options...
Michael J. Brown Posted February 5, 2008 Author Share Posted February 5, 2008 Quoted for 100% agreement! Unless there is a good reason ALL hard surface materilas should be done with the A&D shader. IMHO;) Regards Bri Humph:confused: Well, that just goes to show how old-school I am. I simply never bothered with the A+D materials (or the Architectural Libraries either). I thought I had pretty good control over my material properties by going with Standard. Now I know otherwise. Are there any good tutorials on producing specific results with A+D mats? (besides the Help files - which I will also comb through). Specifically, I've been looking for where it is I directly control the amount (and properties) of reflection a material posesses. There has to be something beyond the Presets (Glass Reflective, Paint Gloss, etc). Link to comment Share on other sites More sharing options...
Justin Hunt Posted February 5, 2008 Share Posted February 5, 2008 There is a pdf that explains the a&D shader in great depth. Its more about what the settings do rather than "us this and this", so you actually learn something. The reflections are controled by the reflection numbers and the BDRF curve. Once again the pdf will explain these perfectly. The pdf is in the help file or folder The A&D is problable one of the biggest steps forward for mentalray. Its really powerful and quite simple once you get your head around it. JHV Link to comment Share on other sites More sharing options...
