32 bit displacement

[Rico_uk]

I've been trying to get a good workflow between Mudbox and Octane but I'm so far unable to get this to work in a production quality and reliable way. I've attached renders from Vray and also Octane. As you can see the Vray displacement is perfect (it has a few more settings of course) but the Octane one doesn't even get close with a 32 bit displacement map. I can use Octane to displace using 8 or 16 bit textures, but this is only useful for very basic displacement, but when using a production character this isn't accurate enough. Also how would you displace both inwards and outwards? I've tried using a normalised displacement with medium grey for background colour, but even this displaced incorrectly. Any ideas?

I'd be really interested in this too.

If we could have a tutorial from mudbox and zbrush through to Octane, that would be cool.

Did you try 2.13 version?

I have been banging on about this for ages and feel a little ignored about it. ZBrush (and I guess mud box too) has mid grey set to zero so that you can displace out and in. Octane works great with out only (ie zero is black). The problem is when you use the shift parameter to bring the displacement back to match the zbrush displacement it ruins the geometry.

I haven't tried it yet. I need to install 2.13 on all my machines, other than displacement everything else works pretty stable. Once this current job is out of the way I'll install and test it.

Just got around to testing the displacement in 2.23, it still has the same problems, doesn't look at all like it should. I'm using a 32 bit displacement map, mid grey out to have no effect, but I'm getting some really weird results, and using the shift just makes things worse. The map works perfectly in Vray.

I really hope we don't have to pay for version 3 to get a version of displacement that works properly, with organic shapes, with positive and negative displacements

[Rico_uk]

yeah me too, hopefully it will all be sorted, I'm sure they're on the case.
