OctaneRender 3 for DAZ Studio [TEST and STABLE] [OBSOLETE]

[AlfaseeD]

If you can send me a simple .duf scene which demonstrates the above issues, I will take a look.

Sorry for the late reply, I hadn't seen this message!

Well, it's not a bug, is how the conversion has ever worked!
An iRay Metallicity/Roughness material is converted in a simple diffuse material in Octane.

The issue is more complex than simply creating an Octane glossy node. The Iray Uber Shader is rendering in Iray in a different fashion to how Octane would render a similar material. For instance, the Car Paint - Cranberry renders as follows (if the Octane Material is changed to a Glossy with an IOR as per the IRay Top Coat IOR).

I know what you mean and I know this is not a simple thing to handle.
However my "desire" is OCDs is able to convert an iRay Metallicity/Roughness in something like a glossy with the maps placed in the right place.

I made a manual conversion and this is the best results I can achieve in Octane:

And these are the parameters:

Almost all products from Daz have this type of material setting, so I would really like for this to be an automatic process since doing it manually is incredible time consuming, discouraging to be honest.

Can you show me (or send me) the Octane Material definition that matches the Iray material pls?

Thanks

I posted a pic of the parameters for the Octane counterpart and that's all I've done, I just created a glossy material with those values and maps.

Basically in Octane I didn't use the metallicity map and the only "trick" is the diffuse color map plugged in the specular with a 1.6 gamma.

Of course I will never get the same results in Octane, but at least there is more fidelity and not just a plain diffuse material.

Following is a pre-release of the next version of the plugin. There is an issue with the Octane 3.05.2 Daylight Environment node, so I will wait for the next Octane release before fully releasing the next DAZStudio plugin.

3.5.2.30
- Compiled with Octane 3.05.2
- Added support for Instances Groups - so UltraScatter and Voxelizer scenes should now work. There are some limitations to this due to some oddities in DAZStudio. For example, if you instance an object of figure which has a child object/figure, the instance source must have it's scale at 100% and rotation at 0.
- Fixed issue where loading a scene whilst the current scene is rendering would cause the Octane Viewport to step rendering in some situations - requiring a plugin restart
- Added "LiveDb material download failed" message when a LiveDb material cannot be downloaded

I am also currently looking at how IRay Uber materials can be better converted to Octane materials (see separate announcement thread for details).

I have looked into this further - but it is not clear from your screenshot exactly which Iray Uber shader image maps you what connected to which Octane Glossy material pins. Can you pls provide an exact mapping of what you want pls and I will code it.
