***BAD BUG (Octane accuracy)...PAY ATTENTION!***

[gabrielefx]

Hi Refractive team,

hi found a bad bug in the Octane for Max accuracy

Octane for Max doesn't respect the 3ds Max accuracy, check yourself with the accuracy calculator.

The conclusion is that if you have a room distant 50 meters from the origin you have to move every time your scene on the origin because Octane will render triangles with gaps and black areas.

I've posted here some examples and the Max scene.
This scene is drawn in centimeters and if you merge it in a new scene setting the units in meters you will get the same results.

why did you attach a photo at the bottom? proves that nature has some bugs too?
scnr
you'r renderings amaze me every time. perfect down to the detail, like pieces showing weld lines...

You have sharp eyes to notice, I was too busy looking at your nice picture...
Doesnt seem like it would be too serious until 100m radius, I guess, still that's good to know, a few of my scenes have been 25m away, but they are nothing like your standard, so it wouldnt have mattered anyway.
Lucky we have you, with your attention to detail, finding these things for us.

Can you try to increase rayepsilon?

obviously yes, it doesn't help.

Almo Nature - very good cat food.

This isn't so much an octane thing as much as the nature of 3d apps. The farther you work from the point of origin, the less accurate the system will run. The same thing happens in max. This is why choosing the correct unit scale for your scene is really important. You might want to change to inches, although doing this mid-workflow is never a good idea.

Yes, this is a problem with reduced precision. I have looked at it and it seems to be worse than in 2.52, so the new geometry processing introduced in 2.55 is probably less precise than the previous system.

Yes, a real problem!

Yes, a real problem!

This is not a problem. You have to work with proper unit scale.
