How to combine (bake) multiple objects in Blender with UVPackmaster and Simplebake

In this video, I'll show you how to bake multiple objects and materials into one object and one material in Blender using UVPackmaster and Simplebake.

He doesnt mention it in the video but to do the initial pack make sure the built in blender addon called "Magic UV" is enabled to get the option to pack UV

Super useful and clear. Thank you Alex!

THE VIDEO I NEEDED !! Thank you sir !

Is it really possible that in such a complex plugin there is no possibility of group baking from high-poly to low-poly?

Always fantastic to watch your take on the topic of uv editing! Is the joining of multiple objects at the end recommended as you would lose references to individual meshes you might need to interact with, say, in a game?

[@AlexPearce3d]

Great question! It does depend on the project and use case. If you can join meshes togetger in the game engine of choice, it's probably best to just do it there, for flexibility. In unity (and probably unreal) , you don't have to worry about joining them, if you have dynamic batching enabled. That will basically join all meshes that share the same material at run time. I don't think webjs does that though, and the more meshes you have the more draw calls and the worse performance (in general).

[@mishraka]

It might be just me but I had to apply smart UV to initialize the whole process. After that, UVPackmaster has been working really well. You did the light packing in the beginning of the video as well. was that necessary?

Very good video well presented and simple to follow. I have one problem using SimpleBake I found and that is I cannot seem to work out how to bake 1 Object with Multiple materials into 1 Material. I could separate and break the mesh into multiple objects but that seems counter intuitive. Is there a method to this or is the way I described the only way to do this?

[@AlexPearce3d]

I don't know to be honest, I think I've always separated before. You can reach out to the developer through blendermarket.com, he is good at responding and would know for sure.

how to use this addon without breaking the texel density? I mean when I pack not only pack ,sometimes break the texel density and also rotate in different ways the island...I prefer to have all my island in vertical...for example a chst or a head... I need the chest and head uv island must be vertical... so it iesay to paint in gimp easier. thx

13:40 “you can not bake with optix” - why? is it wrong or blender won’t allow it?

[@jorgemoises5311]

hey men thanks for your video your link for uvpackmaster is not working anymore.

[@mishraka]

You also spoke about baking lighting few times during the video as a constraint that would change your uv packing process. Are you planning to do a video around that question? Learning to baking lights seem really interesting topic.

[@AlexPearce3d]

The short answer is yes! I don't know when though. I think I did do a video showing it before, but I want to make more of them.

[@AlexPearce3d]

But as far as uv editing, basically you want overlapping faces of its not being bakes, you don't want overlapping faces of you are baking lighting, so those principles are in this video.

[@mishraka]

@@AlexPearce3d could you please place the link to the video you are referring to?

[@mishraka]

I guess this might be the one: kzbin.info/www/bejne/fGiWiH-hopWEo5I

[@AlexPearce3d]

Sorry I'm driving up the coast right now, but yes that's the one! I also made one to show tmhoe to do it with Octane for blender. And when I had made that video, I thought you couldn't bake with your gpu but you can! You just cannot bake with Optix turned on. I also have a video explaining it better, id give the link if I had more time but were just stopped to get gas and I gotta run. I do hope to make a new tutorial that shows uv packmaster/simplebake light baking, it's very similar, but might be helpful for people specifically looking to bake lighting. One thing you have to consider is you may need a little more margin to make sure you don't get seams and texel density should match more closely, because you may be able to tell the difference between a part of the mesh that is higher texel density and a part that is lower texel density. You might not notice it at all if you're not baking lighting.

look like placing lego pieces
