Baking texture from one object to another in blender 2.8?

[uriel]

Hi guys,
doing photogrammetry, and retopology, i am used of the baking system from 2.79. As i do until now, using the blender render engine thaty provide rthat option, “baking”>“texture”, (wich doesnt exist in cycles !)

My question is: will we have this option in 2.8, as the Brender will not be ported ?
will it be available for evee render ? we really need this feature.

please, correct me if it already exist in the pre-release of 2.8 (i cant find it), have a nice day

Hi Damian…
Bake is there, but textures only is not available i am looking for the feature to get a “baking texture” from one object to another… like the 2.79 blender render bake system !
thx

Hi,

you should have no issues with baking any kind of texture from one object to another ( I presume you want to bake the photogrammetry texture to a new image which has more sensible UV mapping on a cleaned mesh object ) - here’s a link to 2 posts that cover the primary methods:

Bakeing 3d model to plane

Is it possible to bake 3d models to plane with all maps like 3dsMax in blender and how?? [artem-brizitskiy-plants-maps] [F1-1024x472]

and

Bake with 2 Uvs with different sizes

Yes it is. Let’s assume your tree section has two materials, the bark and the rings. Each uses a separate map. The bark has it’s UV’s filling the whole space:- [Log_prt1] and the rings also fill the whole space:- [Log_prt2] This is just one object with one UV channel but if you selected the whole object the UV’s would overlap - which is bad for game engines. To create a unified map that gives both parts in one UV space you need to make a duplicate of your original geometry. DO NOT MOVE IT…

I’m sure there are others too.

I think the procedure is similar to 2.79 but with a small number of changes:
Instead of baking > texture, select baking > diffuse.

Step 1:
For the low poly object, set up the materials as in this video, and the UV layer:
For my test in 2.8 I used a Diffuse BSDF material, and the Cycles renderer.
Ignore the bake step in the video.

Step 2:
Select the high poly object, then the low poly object, and then go to Bake > Diffuse. Influence should only be Colour, and Selected to Active = true, and Ray Distance should be a small number, but not 0.

Apologies for poking an old thread, but could someone, anyone please tell me what I’m doing wrong? I’ve been trying to do this on a transparent object and every time, everything just comes out solid black.

Pls halp

same i cant figure out why

I’m not sure it’s even possible to bake transparency (at least I never managed to make it work).

As a workaround color and alpha can be baked separately by plugging them into emission output one by one (into RGB and grayscale images respectively), and then combined into one RGBA image in compositor or any external image editor.
