This Blender Exporter only works with Blender v2.7x
-
Don't use the Blender from the distro repositories. Download the Blender official 2.79 builds from: https://download.blender.org/release/Blender2.79
-
YafaRay only supports one scene in the .blend file. If you have more than one scene, it could cause unexpected results and problems in the new Material Preview Controls.
-
YafaRay v3 has only limited support for multiple YafaRay versions and forks installed at the same time
If you have several YafaRay versions together, make sure that you enable in Blender first the old and later the new v3 in that order. If you have problems, disable both, restart Blender and enable them in that order.
Having several versions could cause in some cases: - Black renders - Random crashes - Inability to enable the YafaRay v3 plugin or all kinds of strange problems
If you have any of these problems, remove any other yafaray folders (or derived forks) from the Blender addons folder and try again. This typically solves most of the problems stated above.
Thank you.
