Texture painting in the Blender plugin?

[grimm]

Does anyone have a good workflow for doing texture painting in Blender-Octane? I have tried to do it using all the methods I know but it refuses to work. I just bought a new drawing tablet and would like to try it out with the new Blender plugin.

No thoughts?

Well I did come up with a workable method, but I don't know if it's the best one or not. What I did was to select Blender's internal renderer and set up the texture painting as normal (UV unwrapping your object, setting up a blender texture for it, and painting). Then I saved the image to a file and selected Octane renderer. I setup the nodes as normal for Octane and loaded the image into the material. I was able to switch back and forth between the two renderers and modify the texture and still be able to see the changes when I would render the object with Octane.

Not the most straight forward method so if anyone has a better one please let me know. Thanks,

Jason

That's the only possible way, since Octane plugin cant (yet?) read in-memory texture data inside Blender. You must save it to a file first and reload for every change. It works the same for Cycles too, afaik.

I do it even less straightforward: I paint my textures in GIMP and use Blender paint at most to create a "guideline mask" that I import as a layer in GIMP. Blender has bad resource management (every texture brush you open is just thrown there without any context or grouping), so I never picked up paining in it..

Cool, thanks matej. I had thought that might be the reason, just wasn't sure. I just bought a drawing tablet so I'm experimenting with do more with it in Blender. Otherwise I would use Gimp or Krita as well.

Actually Cycles is able to read in-memory textures (dont laugh, my hand was shaking )

So its hopeful that Octane plugin will support this too, eventually. But you would want to regularly save your texture work to a file anyway, so it's not a big workflow issue.
