Render Preset

Hi, you can set the filepath property (datablock is scene.render.filepath, but you can just search for filepath) and from here you can use blender relative file notations (// means current blend folder for example, see here : https://docs.blender.org/manual/en/latest/files/blend/open_save.html#files-blend-relative-paths) Blender does not support environment variable in filepath like $HOME and so on.

Hope this answers your question, cheers !

thanks for the kind words ! For now, Render Preset is not aware of properties specific to Per-Cam addon, i could take a look if i have some time, it would be great to do a feature request on the github if you want :) https://github.com/samytichadou/render_preset_blender/issues/new
