B2U - Blender To Unity Prefab and Scene Exporter

by Cogumelo Softworks in Scripts and Addons

Working with Unity has never been easier! 

B2U is the In-House solution developed by Cogumelo Softworks for Exporting Prefabs and Scenes from Blender to Unity. For those that work with interactive ambient, archviz and games that need to export models from Blender to Unity this tool will make your daily work a lot easier!

What is B2U?

B2U is a general-purpose Blender to Unity exporter, that provide a faster, more powerful and easier workflow to export Blender data to Unity

Do I Need It?

If you work with Blender and Unity you know how hard it is to export a simple object using the normal pipeline and the build-in exporter. Most of your time is spent fixing rotation and many other transform problems while other features are not supported at all as Cycles node materials. If you want to master the use of Blender with Unity then B2U is for you.

What Features B2U Have?

B2U was designed as an In-House solution, so it has everything that a studio needs to export your scenes such as:

  • Prefab Export: Export Prefabs with correct transformations (Loc/Rot/Size), Cycles materials, textures, and configure Unity properties inside Blender.
  • Scene Export: Export full scenes with instances and nested prefabs support. Multiple instances in Blender are instances of the same prefab at Unity. Enable the power of static batch in fully exported scenes.
  • Cycles Materials: Configure Unity materials inside Blender using Cycles nodes and viewport.
  • Texture Export: External or internal (packed) textures, we handle it all for you.
  • Automatic Folder Management: Select just one base folder and we handle all the folder management of the exported scene. Or you can set it manually to better suit your project management.
  • Export Groups as Nested Prefabs: Blender groups can be exported as nested prefabs with support to parented object and more.
  • Cycles Lights: Export Cycles lights to Unity has never been easier in our scene importer.
  • Camera Export: Export cameras to Unity and make your perfect frame inside Blender.
  • More Coming! Much more features are coming, so tell us what you need to make B2U the best tool for you?

Why should I buy it?

We are a small studio from Brazil and we have already done some great things for Blender such as Graph Theme and BoolTool add-on. We want to support BF with Blender development as well, so we’re assigning part of all sales for the BF Development Fund. That’s our way of saying thanks to BF for all the good stuff that they have done. 

On top of it, B2U is the Best solution for exporting from Blender to Unity on the Market, so if you just want a tool to work with, B2U is what you need!

    I bought this a few days ago. Very easy to install but a little tricky to figure out. I have a few issues with trying to use it so far. For example, when I try to export my scene, I get an error about materials with problems but no further information. Good product but more detailed explanations on how to use it and explaining some errors would be good. I would definitely recommend this.

    Hmmm... how to install????

    • Cogumelo Softworks about 2 months ago

      Hi. The blender exporter is inside the unitypackage. You need to install it in your project first anyway. Bye!

    Cogumelo Softworks has created something that many Blender and Unity user's have been begging for. The only problem is the 3 min tutorial doesn't walk you through all the steps from A - Z and the manual doesn't either. When I move over to Unity to check and see if the export worked, it doesn't. I installed the B2U unity package into my Unity project before I export, I append the nodes into my Blender scene and use them, I UV unwrap my object...but to no avail, it just won't work when I export to unity. I'm thankful that Cogumelo Softworks has created this...but I just can't get it to work so until Cogumelo Softworks creates a better walkthrough tutorial, I would recommend saving your money and grind through the FBX method and drag your texture folder into the Unity project.

      Hi Ross. We are working in a better workflow for materials and more detailed installation guide for the next version. During this time we can keep contact inbox so we can help you to make it work for your case. Bye!

    Works really well for us, just need to follow tutorial to understand the workflow. Makes life so much easier. Hopefully future update bring support for animation, dubliverts etc.

    Unfortunately this is fatally buggy - it doesn't work for even the most simple use cases (that it's supposed to support!). Some issues are OS X-specific, are independent of the platform you're using. I've had to go in and fix a number of bugs already just to get basic functionality working, and there are still more needing to be fixed to use it to the advertised potential. Giving it 2 stars rather than one, as at least it's a starting point for building a working exporter/importer from.

      Hi rsim. We use B2U in our studio everyday without problems so can you send to us the exactly bugs that you got? That would help us to improve the product for everyone.
