Frequently Asked Questions

The Custom Overrides help says data paths need to be relative to bpy.context.scene. What does that mean?

Check the section about custom overrides above and the Blender documentation about data paths. http://www.blender.org/api/blender_python_api_2_72_0/info_api_reference.html

The post/pre actions help says I should use absolute paths. What are absolute paths?

Absolute paths are file paths starting from the root of the filesystem. From "C:\" in Windows, or "/" in OS X/Linux. For instance: "/home/user/documents/render/image.png"

What does “overrides” mean (for batch renders)?

Overrides are properties (like render dimensions, or the scene) that can be modified in a render job.

Some of my render jobs fail with a “Permission Denied” error. What’s the issue?

Check the output path for your render jobs. Make sure you have write permissions on that folder.

My renders are coming out blank/wrong in batch!

Do you have more than one render layer? In that case you need to select a specific render layer in the batch panel. Otherwise the last layer to get rendered will overwrite the rest.

When I select a format override in batch I get a message about that format not being available in my system.

This happens when you select a format that may or may not be compiled into Blender. Render+ can’t determine which formats were included in your Blender version (API limitation). Available formats can vary between Operating Systems and versions of Blender (official, custom, branch from GraphicAll, etc).

If you’re unsure about a format being available, try a small render using the size override to check it out.

Is there any way to change the path of an output node for each job?

This question applies to having a File Output node in your compositor nodes. You can change the path set for it for each individual render job by setting it in Custom Overrides. Jump to the Custom Overrides tab and add a new override. Use the following data path: node_tree.nodes[NODE_NAME].base_path. Replace NODE_NAME with the name of the node you want to modify. Set the “Data” field to the path you want for that job.

How do I start the batch server manually?

Head over to Renderplus’ addon folder and you will find three files called “start_server_[OS]”. Double click the one that corresponds to your operating system and the batch server will start running

I’m getting an error about network permissions when trying to render

Blender 4.2 introduced online access permissions. This akin to mobile apps requesting permissions for different resources.

Since Render+ can render over a network, it needs permission to use network functionality. You can enable this in preferences > system > network

Here is the relevant page in Blender’s documentation: https://docs.blender.org/manual/en/latest/editors/preferences/system.html#network

I have setup the batch server over a network correctly, but the batches are not starting

If you have set the batch server over a network and confirmed that R+ can talk to the server but batch are not starting or finishing before starting, check the addon preferences. Make sure the blender executable is set.

When Render+ runs locally it fills in the Blender executable from the one running the addon. However there’s no way to do this in a server on another computer, so we need to set a Blender executable beforehand.

How do I connect to the batch server over a network?

When you start the batch server it will try to find out that machine’s ip address in the network. In the client computer, open Render+’s preferences and in the batch tab select the “network” option. Paste your server machine’s ip address in the server address field. Don’t forget to check the port field as well.

You can check if Render+ can reach the server with the “Test Server Connection” button.

If the batch server couldn’t figure out your network ip, you can look for it manually in your system’s settings.
