How can I see textures in the viewport when I create an Octane material from scratch?
Or do I first have to create a Modo material and then convert to be able to see it in the viewport?
With my settings is 1. So the Octane plugin will pick up that same gamma value. If using Modo801 or later, check out the recommended color space settings at http://render.otoy.com/universe.php#42Modo801%20Specifics. Modo901 potentially introduces some addition controls in this area which I have not explored yet with the plugin.What is the default gamma value for textures in modo? 2.2? 1?
Hi Rob - if you want Modo to display the textures in the Modo preview window, then you need to add the textures to the Modo Shader Tree. In which case it is easiest to use the corresponding Texture Locator from the Shader Tree in the Octane Override (since it will do all the conversion of the scales, projections, etc for you). http://render.otoy.com/universe.php#42Projection%20MappingI just want to see the textures in the modo viewport (not rendered) so I can adjust mapping types and scale.
I have implemented this previously, but it is not at a quality I consider worthy for public release. The Octane Standalone material ball renders on the fly, so you can tweak and adjust settings and the rendering of the ball restarts. However with plugins, the generation of the material preview blocks the UI, so you make a change, and need to wait for 500 samples to get the result. So I don't think it is useable. The Rhino plugin implements this by rendering the material thumbnails whilst the app is idle. In Modo, the plugin generates thumbnails for presets when you save to a preset. I'm unsure how it's done in 3ds max. So there is no live material editor like in Octane Standalone in the Modo plugin - sorry. Otoy would need to modify the API to allow this to happen.Is there a way to get a material preview with a shader ball?
You could certainly script this. No one has ever asked for this before, otherwise I would have already put together a script. If you are using Modo801, then you'd need to use the python SDK, however with Modo901 there is the new python TD SDK, which would make doing something like this much easier (probably only a few lines of python?). This is a starting point (Modo901):Is there a way to convert the whole scene to Octane materials at once (script)?
scene = modo.Scene()
for item in scene.items(itype='advancedMaterial', superType=True):
print "Adding Octane Override to " + item.name
