Baking OBJ Texture on a Plane
-
@Dr-Sassi also as an information after my previous reply.. , i am trying to bake normal map and AO onto a plane because i am going to use that image as a texture in another software (CLO3d), I am creating a buckle from fabric and would like to add the image as a texture( graphic) so fabric will look like hard surface buckle. That's why trying to bake the AO and normal map on to a plane surface.

In case you find it useful, I found this the other day. It's a native C4D shader that you can use to generate normal maps. It's listed on the homepage as NLinn Shader and best of all its free.

Hi @smckenzie Thank you! for the information, will look into more depth but i am also trying to do the same for AO and it needs to be onto a flat surface

Hi road-conclusion,
Just to repeat, as some might read on the post with the example file, to have that as a flat projection is a limitation. But set to flat and Fit to Object, it will work without UVs.
The key was to fix the mesh first. Removing triangles, SSD, using the Volume modeling to smooth it, then Remesh it. I then scaled it up.
By the way, I assume the little plane and buckle rotation was accidental.Please explore the file; the two renders are inside the tex folder.
I have placed two stripes on the model, which need a transparent material (alpha) to get the textures fitted to the plane and the buckle.
The camera is set far enough away to get no parallax.

Plugins can be helpful, but history has shown that they might be EOL at one point. Your gained knowledge in finding native solutions will have no EOL.
All the best

Hi @Dr-Sassi Thank you! for the file.. I am exploring the file that you shared.. I see that you did it with render option not the bake. Is that correct?
In this case how we can have a normal map like this? Same buckle is used for this normal map .. , someone did it in Modo, not sure how he did it but i know that he used this exactly buckle that i shared.. and he came out with this AO and Normal map . I don't think he changed the mesh type but he mentioned he softened only the corners.

Hi road-conclusion,
There are different formats for Normal Maps: Tangent, Object, and World. All are useable, but if not mentioned, it is diffcult to know what you need, you mentioned some 3rd party apps.

Here is the buckle with a Plane as a base for baking; as initially described, this one needs to be fully UV wrapped, so you don't get overwritten areas. This one is done via baking.

The image below is a jpg and not suitable for normal mapping, use the EXR, float,linear, as provided in the zip
All the best

Thank you! @Dr-Sassi ,, yeah the thing i am trying to find the way without UV unwrap .. but thank you for all the help..Appreciated!

You're very welcome, road-conclusion.
I want to encourage you to get familiar with UV; at one point, you need to have that skill anyway.
Have you tried my little drill? It takes perhaps less than five minutes.
Cheers
-
@Dr-Sassi I know how to unwrap but some of the OBJ that i need to work on are triangles and changing them to quads takes time and also removes the details..
sorry didn't understand your question which drill? -
Thanks for the reply, road -conclusion,
Sorry, I thought I had attached it, but if you know UV and avoid it for other reasons, please ignore it:
https://stcineversityprod02.blob.core.windows.net/$web/Cineversity_Forum_Support/2023_PROJECTS_DRS/20230305_UV_challenge_drill.zipYes, improving a model takes time, and bad models will take later on a lot of work to fix things, a balancing act.
I understand you have your ideas about this, and you don't want UV.
My best wishes, and have a nice Sunday Evening.

@Dr-Sassi Thank you! have a nice evening to you as well

Very kind of you, road-conclusion, thank you.
