Genesis Eye problems with Nvida Iray with extreme xyz locations

TromNek

I noticed if I have my Genesis 9 postitioned far from the center of the scene (in two coordinate planes), the eyes render with anomilies using Nvida Iray.

I discovered it's a problem with Gen 8, 8.1 and 9, only with Nvida Iray (both display and render).

Attached is a screenshot with Genesis 8 (left), 8.1 (middle) and 9 (right). At coordinates x=1500, y=0, z=1500

Are the any settings I need to set for Iray that fix this ?

I solved the problem by creating a null node, parent all my objects to that node, then translate xyz for that node so where I'm rendering is close to center of the real world.

But it would be nice not to have to shift that null node for different locations scene.

An Iray setting would be much nicer.

You can change instance optimization to either memory or speed - but you must change it.

The problem comes from lack of calculation precision when getting to far from the set origin.

( btw, I should have mentioned I'm runnning DS 4.21 )

Thanks, It fixes setting it to Memory (setting to Speed didn't fix it).

Just tested it on DS 4.16 also. Same thing

Memory fixes Speed doesn't.

I think I'll use the Optimize for Memory setting instead of creating a null node that was my temporary fix.

Thanks so much !
