Yes... I know... Will be my running gag! ;)

Thank you for the kind words!

This can by a way, but don't you have any problems with antialiasing?

@@ChristophWerner Yeah, posiblelity. Actually an old way, there are several addons now. ^^

Some Augmented Reality applications need realistic baked content for scenes. Another case is to bake fixed light for a room or terrain for an architectual subject. This is mainly interesting for realtime presentations, if you don't have the GPU power to render realistic light settings in realtime. There are more cases like optimising the amount of renderered materials for example. Rendering less materials is faster for realtime apps and needs less memory. There are much more use cases.

@@ChristophWerner Dankeschön, mein Lieber! ;)

Immer gern! :)

You have to hold the ALT-key while selecting an object to open the Selection Menu. If there are multiple objects placed at the same position and overlapping each other, you can choose the one you need.

@@ChristophWerner Thanks Christoph!!! :-)

If you're working with Blender materials there's no need to mix them. What is the reason you need this?

​@@ChristophWerner, I would like to know that as well. I am working mainly for OpenSim/Secondlife. There you have a diffuse map with included alpha channel (e.g. .png or .tga), a shininess/specular map (also including alpha channel, which does a special work), and a bump/normal map, also with alpha channel, which does a "glow" work. So I am searching for a method to bake all three textures with alpha channel included, to be able to test those OS/SL features in detail and continue with my Blender addon development.

I've created a new short tutorial for this topic, after several people asked for a it: kzfaq.info/get/bejne/ldh5gMSmseDTZmg.html

@@ChristophWerner, many thanks :) Das hat mir darüber hinaus die ersten Einblicke in die Anwendung des Compositors und seinen Sinn gegeben … sehr hilfreich.

@@tomernst1370 Danke. Gern geschehen.

Basically all is possible. I'm not really sure what you're exactly trying to achieve, so I can't give you more feedback without seeing your project in this case. Sorry. I recommend everyone to visit blender.stackexchange.com first. There you'll find answers for nearly all Blender questions and can post your topics in detail, with much more posibilities than on You Tube in a comment box. Thx!

Why? Basically the steps are the same, just some options changed but it still works as described, also in Blender version 4.x. Do you miss something?

@@ChristophWerner no actually i followed this process and it worked just fine. Sorry for the confusion, for some reason i thought there might be some tools to use differently. Thank you for the video!

See the "High Poly Mesh" as the source and the low poly mesh as the target for baking. You need always a source mesh to bake from.

I do it just to have a clean shader tree and be sure all is baked right. But you're basically right, internally it will be handled like an emission node. So we may don't really need it at this point.
