OctaneRender for Modo 3.03.3 [STABLE]

[face_off]

Do I have to see the gamma to 1,0 or to 2.2.
I am asking this because I am confused, since the value should be linear, yet the image must be colored in order to get the rgb from the normal map.

I have asked his before, and I vaguely recall that the gamma is ignored for normal maps. But I suggest you ask in the Octane Standalone forum to confirm this.

how roughness is interpreted by the octane render engine, ... is black 0 roughness, and white 100%, or black is 100%, and white 0 roughness.
I am asking order to insert the info from substance painter to octane render as correct as possible.

black = 0 (not rough), white = 1 (very rough).

I've been thinking maybe a tool to convert Substance materials to Octane materials. I am unsure on what the demand for it would be like though.

I could use that. I would buy that.

Hi Rick - I just had a quick look it this....the .sbsar format is a binary format, and there is no public API available to read it. I'd be interested to hear your and Vlad's workflows. ie. Do you create the material in Substance Painter and then load into the Modo Substance plugin? Or are you exporting from Painter to png then loading those texturemaps into Modo?

Hi Paul,

I use in my workflow the bitmaps that I link into octane shader, but I think there must be some adjustments to calibrate the specular/glossiness workflow, (witch in octane translate to specular/roughness).
I think a great way to study the calibration Paul will be to read these 2 guides https://www.allegorithmic.com/pbr-guide .

It will be nice to make sure the plugin works also, https://www.allegorithmic.com/download/ ... d_free/195 .

The sweetness of my workflow is that I insert 4 bitmpas or 5, depends on the material need, and I am up and ready to render.

My slow down, is that Substance Painter uses metallic/roughness workflow, for memory reason, and I need to adjust my substance designer/substance painter materials.


Substance Painter is a free 15 days trials, as designer tool, so Paul maybe you can get some chance to play with these, make some textures imports, and get the calibration there , as you did with modo-ctane.
Cheers,
Vlad

I have refreshed the installer at the top of this thread with:

2.22.2.67
- Additional fix to correct colormapping issues with the octane.command downloadLiveDb command thumbnail generation.
- Added the Step checkbox and Control Points input in the Gradient 2 texture node

Hi Vlad - yes, I have tried the Substance Painter trial. The conversion of Substance materials into Octane materials is something I can potentially streamline in the Modo plugin, however getting deep into the maths behind PBR (which is over me head) in order to decode how to convert substance roughness to Octane roughness is out of the scope of what I can do in the near future. But if you determine the conversion formula, I can see if it can be incorporated into the Octane plugin. Sorry cannot be more help. There are too many other cool features to integrate into the plugin in the near future

Hi Paul,

I will make test for maps calibration, then I will share them for plugin octane adjustments.

I have refreshed the installer at the top of this thread with:

2.22.2.68
- Added new Octane node type "Node Graph", which has a single pin out which must be compatible with the pin that it is plugged into. Copy and paste from an Octane Standalone Node Graph into this node's XML property.
- Added ability to attach an Octane Nodes to assembly inputs and outputs. There is less error checking on pin compatibility, so you may get an Octane or plugin error message if you connect the wrong node into the wrong pin via an assembly link.
- Fixed Horizontal and Vertical Wrap alignment issues when the projection type was UV Map

Hi Paul,

Can you make the octane render plugin read tga (targe files), because I think the reason why the octane render plugin does not work with substance plugin is that substance plugin saves the files as tga files to store data.

About the conversion I do not think it is necessary if you can make this work, because we can convert the data in octane designer or painter when we import images.

You can download the plugin from thefoundry.com (substance plug-in)

Hi Vlad - I just tested TGA files, and they worked OK in the plugin. What specific problem are you having with them pls?

Thanks

Paul
