Step size does not seem to matter, but for Volume padding, these few full body objects will not show at all unless I use 0 for volume padding and then they are completely black....have not been able to figure it out. Any Suggestions?</P> Wed, 16 Jan 2019 14:30:11 GMT Anonymous 2019-01-16T14:30:11Z https://forums.autodesk.com/t5/arnold-general-rendering-forum/some-objects-don-t-seem-to-react-the-same-in-volume-renders/m-p/11039320#M3054 <P>.I am having issues making some objects volume objects.

I presume you have assigned a <EM>Standard Volume</EM> shader to the objects. Can you share a simplified scene or if that's not possible a screengrab of your setup?</P> Wed, 16 Jan 2019 15:08:58 GMT https://forums.autodesk.com/t5/arnold-general-rendering-forum/some-objects-don-t-seem-to-react-the-same-in-volume-renders/m-p/11039321#M3055 lee_griggs 2019-01-16T15:08:58Z https://forums.autodesk.com/t5/arnold-general-rendering-forum/some-objects-don-t-seem-to-react-the-same-in-volume-renders/m-p/11039322#M3056 <P>Here is a screenshot of the scene with the volume Padding at zero-black object when VDB and ball work fine, and a separate shot if I turn the Volume Padding on at all....object disappears</P><P>Not totally sure if object is closed....but have had success on several open objects</P><P><span class="lia-inline-image-display-wrapper" image-alt="3047-screen-shot-2019-01-16-at-102711-am.png"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1041042i6FD5AA1F6264D669/image-size/large?v=v2&amp;px=999" role="button" title="3047-screen-shot-2019-01-16-at-102711-am.png" alt="3047-screen-shot-2019-01-16-at-102711-am.png" /></span></P><P><span class="lia-inline-image-display-wrapper" image-alt="3048-screen-shot-2019-01-16-at-102755-am.png"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1041043iD1E48FDD4E86EB4C/image-size/large?v=v2&amp;px=999" role="button" title="3048-screen-shot-2019-01-16-at-102755-am.png" alt="3048-screen-shot-2019-01-16-at-102755-am.png" /></span></P> Wed, 16 Jan 2019 15:32:08 GMT https://forums.autodesk.com/t5/arnold-general-rendering-forum/some-objects-don-t-seem-to-react-the-same-in-volume-renders/m-p/11039322#M3056 Anonymous 2019-01-16T15:32:08Z https://forums.autodesk.com/t5/arnold-general-rendering-forum/some-objects-don-t-seem-to-react-the-same-in-volume-renders/m-p/11039323#M3057 <P>Thank you for helping Lee, I finally stumbled on the answer....seems the Range in the Shader Network needed to be adjusted to levels I have never been near to get the volume to show .(Like values of 20 in Input max and .02 in Input Max</P> Wed, 16 Jan 2019 23:47:11 GMT https://forums.autodesk.com/t5/arnold-general-rendering-forum/some-objects-don-t-seem-to-react-the-same-in-volume-renders/m-p/11039323#M3057 Anonymous 2019-01-16T23:47:11Z https://forums.autodesk.com/t5/arnold-general-rendering-forum/some-objects-don-t-seem-to-react-the-same-in-volume-renders/m-p/11039324#M3058 <P>Glad you got it to work Louis!</P> Thu, 17 Jan 2019 07:59:40 GMT https://forums.autodesk.com/t5/arnold-general-rendering-forum/some-objects-don-t-seem-to-react-the-same-in-volume-renders/m-p/11039324#M3058 lee_griggs 2019-01-17T07:59:40Z
