Rename any instance of scene layer or render layer in code with view layer The RenderResult struct still has a listbase of RenderLayer, but that's ok since this is strictly for rendering. * Subversion bump (to 2.80.2) * DNA low level doversion (renames) - only for .blend created since 2.80 started Note: We can't use DNA_struct_elem_find or get file version in init_structDNA, so we are manually iterating over the array of the SDNA elements instead. Note 2: This doversion change with renames can be reverted in a few months. But so far it's required for 2.8 files created between October 2016 and now.

Rename any instance of scene layer or render layer in code with view layer The RenderResult struct still has a listbase of RenderLayer, but that's ok since this is strictly for rendering. * Subversion bump (to 2.80.2) * DNA low level doversion (renames) - only for .blend created since 2.80 started Note: We can't use DNA_struct_elem_find or get file version in init_structDNA, so we are manually iterating over the array of the SDNA elements instead. Note 2: This doversion change with renames can be reverted in a few months. But so far it's required for 2.8 files created between October 2016 and now.
