Principled Baker - Bake PBR textures with a few clicks

ShadC · August 16, 2019, 2:09pm

Can I bake a single object with multiple materials on it?
Thanks.

Yes.

update 0.4.5

(optional) new UV map without overwriting existing and select
(optional) new UV map set as active render
Combine List checkboxes
fixed: missing alpha from channel in Combine Channels

The update is for 2.80 only, too.

New UV map is a feature request from @aryeramaty.

update 0.4.6

individual Samples option
individual Color Depth option
Color Depth per entry in Bake List
fixed: Texture Folder always created

The update is for 2.80 only, too.

Big thanks for your hard work .

update 0.4.7

duplicate object option
fixed: slow detection on large node trees

The update is for 2.80 only, too.

Duplicate objects is a feature request from @aryeramaty.

Duplicate objects duplicates the objects, reduces to one UV map, adds a new material and renames.
It works in Single/Batch mode only. (for now)

Warning: The duplicate object feature crashed Blender sometimes during tests!

The latest update doesn’t work for me (doesn’t work = blender give me an error when I enable it)

BTW I’m using the daily build

DanielEngler · August 22, 2019, 5:19pm

I tried the add on with the daily build, but I couldn’t reproduce the error.
PBAKER_AddSuffixPresetObjectDisplay is defined in pbaker_preset.py.

Maybe try to delete the __pycache__ folder in <config_path>/2.81/scripts/addons/Principled-Baker-master/ and restart blender.

Rakqoi · August 22, 2019, 6:25pm

I had that same error in 2.80 (stable), 0.4.6 installed fine.
Deleting the __pycache__ folder fixed it for me and 0.4.7 installs as well.
Thank you!

@DanielEngler I have some questions related to this tool:

Why UV maps are a requirement for hi poly meshes? Most of the time you don’t have uvs on your hi poly. I get an error every time when I try to bake… Also having at least one material on your hi poly is a requirement. sometimes you want to bake only the normal map from a sculpt. you don’t need a material for that
Is it possible to do a bake to itself - low poly to low poly - in order to bake the round edge shader(bevel node)?

BTW great tool! Thanks for sharing.

DanielEngler · August 23, 2019, 5:41pm

Well, than these are bugs. I’ll fix next week.

With “Single/Batch” or “Combined”. The round edges from the bevel node are going into the normal map.

DanielEngler · August 27, 2019, 4:31pm

update 0.4.8

Selected to Active: autodetection/manual detection reduced to Normal Map only, if one selected object has no material
Selected to Active: new material will only be added to active object, if “Add New Material” is enabled
fixed: Selected to Active: UV maps for selected objects necessary
fixed: Selected to Active: only baking Normal Map not possible without materials
fixed: Selected to Active: only baking Wireframe not possible without materials

The update is for 2.80 only, too.

DanielEngler · September 2, 2019, 3:41pm

update 0.4.9

duplicate objects for combined bake mode
join duplicate objects option for combined bake mode

The update is for 2.80 only, too.

DanielEngler · September 9, 2019, 4:00pm

update 0.5.0

vertex colors: bake selected/active render/all/n-th
fixed: missing detection for value differences over multiple materials/objects
fixed: detection for value differences for some BSDF nodes not working
fixed: false detection of not linked inputs in groups
fixed: wrong colors from some mixes with AO

The update is for 2.80 only, too.

Great addon! Have you considered adding “bake material/image to vertex color”?

DanielEngler · September 9, 2019, 7:06pm

Thanks!
I don’t think, I’ll add this feature. This type of data transfer is something for an other add-on.
Isn’t there already an add-on, that can do this? I can’t remember.

I haven’t looked into vertex data and uv maps, but this shouldn’t be too hard to make. Sample the color of every vertex at the x and y location of the uv map on an image and put r, g, b in vertex color data - or something like that.

Vralsza · September 9, 2019, 7:13pm

Would be amazing! Up until 2.8, bake to verts was a feature of Blender Internal. As that’s no longer included, there’s no easy way to accomplish this in 2.8. The closest thing is using a baked image as a canvas base for Dynamic Paint but the result is dark and blurry compared to the previous BI bake method. Thank you!

DanielEngler · September 10, 2019, 5:31pm

With this add-on you can transfer image data to Vertex Colors. It’s can be found it in the Shader Editor Toolbar.
There is no check for existing UV Map and Vertex Color.
The word “bake” is an exaggeration!

@Vralsza: You can be the first test candidate for a brand new add-on.

edit: here is the “official” thread: Bake to Vertex Color - Transfer Image Data to Vertex Color - #2 by DanielEngler

Vralsza · September 10, 2019, 9:16pm

SUCCESS!!! Thank you, you’ve saved Blender 2.8 for me!
Just did a quick test and it seems to work for me! I’ll keep using it and see if I stumble on any bugs though.
Thank you again for this!!!

update 0.5.1

fixed: displacement working with displacement node only

The displacement from with and without a displacement node does differ!
This means the baked results from with/without displacement node can not be used interchangeably. The baked results without displacement node may also lead to unwanted results in other 3D software like games.
This fix is only there to have the option to not use the displacement node.
