Douglas Ferrin Posted August 23, 2022 Share Posted August 23, 2022 Greetings all! I've never used the hair material before and don't understand why I'm not getting any specular effects. I’ve tried everything I can think of, but I have a feeling I’m missing something basic. Anyone? Thanks much. Doug F Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted August 23, 2022 Hash Fellow Share Posted August 23, 2022 Hi Doug, First make sure that the light that is in the position to cast a specular highlight has "Specularity" ON in its properties. Cool-looking head! Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted August 23, 2022 Hash Fellow Share Posted August 23, 2022 Here's a sample PRJ that shows specular on hair in v19.0p hairtestForSpec03.zip This is the standard specular. Better looking specular can be had with the mu hair specular shader but that is another topic. Quote Link to comment Share on other sites More sharing options...
Douglas Ferrin Posted August 24, 2022 Author Share Posted August 24, 2022 Hey Rob, What would AM do without you? Thanks so much for the advice and the compliment! As you can see, still not working on the guy, but rendered fine on my hairball. I'm thinking maybe there's a bug in my project file? I'm going to load the model into a new project and see how that goes. Hope it's not a bug in the model. One way or another, I'll show you how it goes.

Douglas Ferrin Posted August 24, 2022 Author Share Posted August 24, 2022 Whoops. Here's the screenshot. Quote Link to comment Share on other sites More sharing options...
Douglas Ferrin Posted August 24, 2022 Author Share Posted August 24, 2022 Rob, OK, bringing the model into a new project worked. Hooray. I need to tweak the settings - I'll have a look at the tutorial you sent - but anyway it's working. Thank you so much again for your help! All my best, Doug Quote Link to comment Share on other sites More sharing options...
Douglas Ferrin Posted August 27, 2022 Author Share Posted August 27, 2022 Rob, If you see this, could you please tell me about the mu hair specular shader that you mentioned. A few searches on the forum brought up nothing. Thanks very much! Doug Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted August 27, 2022 Hash Fellow Share Posted August 27, 2022 It's mentioned in this post... It's something you choose in Surface>Specual Render Shader Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted August 27, 2022 Hash Fellow Share Posted August 27, 2022 It has a lot of parameters that are tricky to set right. I used it on my Al Capone Head https://forums.hash.com/topic/40421-possible-human-head-tutorial-subject-al-capone/?do=findComment&comment=371829 Quote Link to comment Share on other sites More sharing options...
itsjustme Posted August 27, 2022 Share Posted August 27, 2022 I couldn't find it in a search, but, I made a PDF the last time I found it...so here is what I have. It's a portion of a thread where all of the controls of muhHair are explained. Hope that helps. muhair.pdf 1 Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted August 27, 2022 Hash Fellow Share Posted August 27, 2022 I had never known what the Kajiya-Kay shader was for until I read that thread. Quote Link to comment Share on other sites More sharing options...
Douglas Ferrin Posted August 27, 2022 Author Share Posted August 27, 2022 Rob and David - thanks much for all the info. I'm not sure if mu-hair should be built in to mu AM, but it isn't; I somewhat combed through the links you two sent, but didn't see a download for the actual shader. Do either of you have a link? By the way, great Al Capone head Rob! Here's an update of the head I'm working on if you're curious. Incidentally, did anyone ever make just a face rig, and an installer? Thanks much.

Fuchur Posted August 27, 2022 Share Posted August 27, 2022 It should be built in current versions. You are using something recent (after v15 or something like that), right? Just to mention it: You will have to activate shaders in the rendering dialog of A:M. Best regards *Fuchur* Quote Link to comment Share on other sites More sharing options...
Douglas Ferrin Posted August 27, 2022 Author Share Posted August 27, 2022 Hi Gerald, Yeah, I'm using v19; I know to look in the render dialog, and that's where I'm not finding it. ideas? Doug Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted August 27, 2022 Hash Fellow Share Posted August 27, 2022 Doug, In the Render settings you just turn "Plug in Shaders" ON, you don't set any particular shader. The two hair shaders only appear as options in the Surface Properties of a Hair Emitter and must be set there. Quote Link to comment Share on other sites More sharing options...
Douglas Ferrin Posted August 28, 2022 Author Share Posted August 28, 2022 Yep, and there it is. Thanks Rob and Gerald. Quote Link to comment Share on other sites More sharing options...
