Object Normal in world space pass?

[jasonhuang1115]

Hi,

Can someone shed some light on how to generate the Object Normal pass in world space?
I tried to use the Normals_RE listed in the Render Settings, but the result yields unexpected when I use it for doing environment reflection in post and the result is also different from what I got from mental ray.

Thanks,
Jason

I asked about this a while ago so be interesting to see if an answer pops up?

The Normals element is in camera/ray space. To get the normals in world/object space, use a VRayExtraTex element and connect it to a samplerInfo node.

Hm, from what I see, the samplerInfo texture does not output the normals in object/world space. You can get the world space normals by exporting to a .vrscene file and modifying that, but looks like it is not possible for the object space normals. I'll add a feature request for this.

Thanks for the reply Vlado. I am not familiar with the modifying .vrscene workflow. Hope to see couple handy Render Elements of Object Normals in both world and object space in the future build.

Could I ask we get a texture node for it as well as a render element option. Handy for texturing having access to object normals in a texture.

Thanks

I also need world space normals! Is there any updates on this issue? anybody that knows a workaround?

[vlado]

Which build of V-Ray are you using? In recent builds you can select the samplerInfo node and add the "V-Ray additional textures" attributes to it - one of them is "Normal World", which you can then connect to an Extra Tex render element to get the world space normals.

You totally saved my day! Thanks! A quick heads up for anyone who would like to try is that I first connected them per induvidual channel. that doesn't work. You have to use "vrayNormalWorld" and not "vrayNormalWorldR","vrayNormalWorldG" and "vrayNormalWorldB".

Thanks again!
