Wine Glass Issues?

LadyDustBunny

I'm just starting out here and decided to do a simple wine glass to learn how to create a glass look. The wine glass was created using a CV curve in Maya. For the shader, I'm using mia_material. I'm very new at all of this and I keep having this happen. It's this weird black patch that changes depending on the angle of the render. Any ideas?

Do you have a cubemap on by any chance?

What ace said... and Is that inside a box with all sides intact? Btw You should make it more transparent. It reflecting way too much in my opinion.

So I deleted the box I had put around it and that seemed to be the issue. Now, I'm just having a problem with the actually shader looking like a wine glass. The top part isn't translucent enough and just grey. Should I just tweak around with some of the attributes of the mia_material? Or is this obviously something different.

mental ray? I'd dump it in favor of Vray, it does glass incredibly well.

vray is very good with presets but you'll learn a lot more with mental ray and imo its a much more powerful rendered. as for the wine glass most of what you see with glass is reflection and refraction so rending it in a white box is asking for trouble. try creating a very simple environment to render in and see how you fare

Thanks so much for everyone's help! I tweaked some of the settings in mental ray (I'm new to using that as well) and things are starting to look much better!
