settings materials for animation

hi everybody...

simple question... how can i set materials in octane when i want to render an animation from blender?

usually for still images i just export the obj in octane and then work on materials. but with animations there is no way i can set materials in this way.

I saw that changing options in blender materials affects also octane material, but looks the relation between options is quite messy.

any help with this?

Hi Sdados,

once you're done working with the materials on a still image save your project and then ensure to uncheck the 'Replace' checkbox before starting the animation. This way the exporter will only update the obj and let the ocs file alone. The filenames must match but this will be the case if exporting both still and anims using the script.

here i come again with another question! :D

now i think i understood how to make an animation... there is a little problem left. i cannot find the rendered images.
i set the path in the box just above the render animation button, but then i cannot find them where i wanted to put them.

i tried many variations... relative path, absolute path, with the name, no name, writing also the extension (as .png for example) but i still won't find them!

what am i doing wrong?

The plugin is supposed to build the filename based on the following parameters: animation output, project name and frame number.
So if you have the following:
- Animation output: C:\Output (must be an absolute path)
- Project name: myproj (no path, no extension)
- render frame 25
the image should be C:\Output\myproj_0025.png

However, on Windows the actual parameter given to Octane is C:/Output//myproj_0025.png ("/" or "//" instead of "\"). Blenders accomodates well with that (I could check the obj and mtl files are properly created), but I don't know if Octane does too as I can't test it on Windows. I'm pretty sure I didn't alter the original code from Enrico for this part and was assuming it was fine.

In order to check, please start blender from command line, ensure verbose mode is on in the 'Octane System Setings' panel, render an anim and check the output from the console. The full command used to start Octane will be shown with all parameters.

sorry... i still have problems with materials in animations...

that's my workflow: i export the still render, i set the materials and then i save the .ocs file over the exported from blender one. i come back in blender, i uncheck the "replace" option next to the project name, and then i click on "render animation".

the animation starts correctly, but the materials are the default ones... :? :oops:

some help please?

thanks very much!

Can you post a small test scene here?
I'd also like to see the console output from Blender when exporting the still with 'replace' and then rendering the anim (without replace of course)

yoyoz... first of all thanks again for helping me. now is working... im sorry to bother the forum with my problems but to be honest i think i was doing the same things when it was not working... but probably not :D

sorry again, ill try to do more experiments on my own next time before asking.

even if octane and exporter still needs improvements, seems now they are working fine for me.

sorry and thanks again :)
