Maya 18 Arnold 3.1.1 mesh does not appear on render

[Anonymous]

Hi,

I try to render an imported mesh but it dosen't appears in Arnold render. It appears in the viewport and also in software render. The mesh seems completely transparent, however it uses the same shader as the mesh(a cube) behind it.

I've attached an image about it.

How can I make it visible in the Arnold renderer?

Thank you.

Have you tried the basics, like assigning a fresh aiStandardSurface with default values to see if that renders? What about loading the mesh into a fresh scene?

Use a utility shader for debugging.

But look at those warnings in the script editor. The uvs are messed up, and it looks like the vertices and normals are bad too (nans and infs)

Try cleaning up that geo

Thank you for the answers, I've tried both things but none of them worked for me, however I've tested through my whole creation process a few times (I import my raster images to Illustrator CS6 convert them to SVG and then import them into Maya) and it turned out if I make an SVG from a 72dpi raster image and then I import it to Maya it doesn't appear in Arnold render. But when I convert the image to 300dpi (with the same size 800*600px) and then I convert it to SVG and then I import to Maya it does appear in Arnold render! Its approximately 6 times smaller in viewport when imported but I can scale it up as big as I want and it can be rendered with Arnold perfectly no matter how big it is. It sounds strange and I don't know why but it works!
