Bake Texture + Emmision = Output, Add Mix Shader Then Copy Bake Texture Add Vector Mapping + Texture Coordinate Assign To Reflection
Thank you for experimenting and sharing your results. Seems to be a good possibility for CG elements in real footage...
I'm just over a year into Blender, and reached the point where baking is relevant to what I do. This is right in my area because I do a lot of camera animation in 3D scenes.
So, thanks very much for this. And, I'm hoping you've done some follow-up tuts on baking. Thanks again.
i am coming for a long way .... trying to know what´s baking.thanks a lot..................now i know it...much love
Hi Sardi, thanks for a very informative tut. Blender has an option in the add-ons options of 'Animated Render Baker' which gives a button in the 'Bake' window labled 'Animated Bake'. Can I suggest a tutorial on the correct way to use this. I am trying to bake materials to an animation and have had limited success with this function. Thanks again Sardi.
Thanks for the suggestion Tony, I'll take a look at it.
Whoa whoa. You didn't show us how to make the glossy work correctly.
Great tutorial, as usual. But! You could spend a couple of words on "Optimizing your Unwraps". I mean averaging (Ctrl+A) and packing (Ctrl+P) the islands to maximize their coverage in the Texture Atlas and minimize the (wasted) empty spaces. This would intrinsically produce a higher quality, being less stretched.
Great video! Is it possible to bake textuers in cycles and use them in Blender Render to effectively get Cycles quality in Blender Render?
Yes you can use baked cycles textures in Blender Internal. Whether that gives you a better quality image is debatable is the textures were still Cycles rendered.
Sardi Pax Because I'm trying to use a scene for a game and in Cycles Render it's beautiful and "softer", whereas in Blender Render (which is the only way I can load it into the game engine properly) it looks harsh and "bitter".
Thank you -- so much info and all of it useful!
Yes very interesting and very quickly done.
if you only have emission shader (from bake), why not render animation with 1 sample?
Hi, great question. You can indeed do that but you may find there is additional noise at extremely low samples, due to the way the render engine works. I would suggest experimenting with each baked scene to find the minimum that is acceptable. Also, if you included some un-baked elements, they would require higher samples of course.
How do you bake texture only in cycles or is that not possible - there is no tyextur only option in the bake menu - would appreciate your feedback
You can bake Diffuse only (for example) by clicking the 'Combined' button and selecting what you want to render. Diffuse will contain the colour information (if that's what you meant by texture).
Yes, I was talking about texture only - not normals or lighting or AO - But i see now what I need to do - apprecatae the reply
Hey Sardi, sorry to bother you but I'm trying to find out how to bake my textures using cycles in an animation I'm doing with animated character's & I can find nothing on youtube about how to do that except for those that only animate the camera not the subject of the bake. Is it possible to bake the textures of a full animation & if so what parts could I bake? I strive for realism because that's my preference, I'm also using the Manuel Bastioni Laboratory for the character's I'm trying to bake. I made a 120 frame animation of an elven woman doing a Matrix leapwhich has been rendering for the last 5 days on & off at 1 frame per hour. I'm poor so my computer is crap. I can't upgrade it because it's to old ( I don't even have a recognoizable gpu Geforce 210, hell I can't even run Blender 2.8) & I can't afford to get a better one as of now so this info would be a life saver to what I'm trying to accomplish. Thx in advance.
Hi, the video you commented against shows the basics of cycles texture baking you can animate the resulting scene by just rendering everything with a texture as an emission material (shadeless) and use the OpenGL render engine to actually do the animation render. However, be aware that if you have anything moving (other than the camera) in the scene, you will struggle to have an animated bake (eg moving shadows). There are cheat ways around such problems, for example, render your figure as a silhouette, then apply the movie as the texture to (for example) the floor as an overlay. You could do something similar with reflections. Hope that makes sense and gives you some ideas.
Thx for getting back to me so soon. I wasn't speaking against your tutorial, it's inspiring. I just needed more. As I said my computer's a dinosaure & the animations I'd like to do need this baking feature. I think I grasp your suggestion but I still don't know what I can bake on my character's. I'm guessing by your reply not the shadows, gloss or transmission. Am I right? Sorry to be a pain but I'm really trying to get some things out that I can share. Thx again for your help.
Thank you for the tut. Lot of information. One question I've got. As I've set the scene up, I have the sphere reflected int eh side of the cube, but when I bake the objects the cone is reflected instead. Any ideas? Tried it a couple of different times. Same result.
IMHO, your tuts should be mandatory with every copy of Blender.
Sardi, so, this kind of baking is useful for Non-animated scene, where there are staticts.objeects? but I think the results are very meaningfull and nice, for renders or statics situation of interioral environment, right?
Reifus Ruffus Hi, you can use the technique for animation as well, you just have to beat in mind that the lighting is not dynamic so doesn't change even if the camera position or object positions change. it can cut render times significantly.
0:11 "very quickly" *tutorial is 20 minutes long*
Really good video :D. It's sad that when you bake glossy & reflection, the result is horrible !
Most helpfull tut about baking in Bl cycles on youtube!..thx a lot :)
Hello sardi, I'm not having any luck baking in cycles. I get it to work in blender render however in cycles I'm having several problems. I'm only trying to bake 1 object with a few materials. The issue I'm having is if I have say 4 materials only 1 or 2 bake and the others are missing. I went through each material, added the image texture node, select the node in each material, and always seem to get the same result? Any ideas?
Hi, I just tried with 4 materials on one object and didn't have a problem. Are you making sure that in each case the image texture is set to your Texture Atlas image?
Sardi Pax
I was just using a uv image I'll try the atlas.
This tutorial was super helpful thank you!
One question: I baked a big scene and it took hours to bake because I was a noob and didn't first bake small to see if everything would work out. When it was done, I accidentally clicked off the baked image and I can't seem to find it. Is it still saved in internal memory somewhere or am I totally hosed and have to do the whole baking process again?
I got to the part where you packed the image/saved the image but I didn't do that before I lost it.
Thanks for the tutorial though mate.
Hi Chris. If the image is still in the buffer, you can find it by opening the UV Image editor then click the box to the left of the Image name. You will see whatever images are in the buffer so you will see your bake if it's still there. Clicking it will let you bring it up then you can click the Save Image option. If it's not there, I'm afraid it's gone :(
finally a really clear explanation. Thanks!
Can't thank you enough for all of your tutorials. Never disappointed. Quite well done.
Best wishes.
Thank you :)
fascinating, thanks a lot!
This is great! Someone finally explained how to use the Texture Atlas!! Thank you.
I do have a question. Would this work if we were, say, taking many high-poly objects and baking them into an image to apply to a single plane? It used to be done in Blender Internal, and it was quite easy. Cycles is giving me one headache after another.
Thanks again for your tutorial!
Hi James, do you mean creating a Normal Map to simulate the high poly geometry? I believe you can bake to normal maps just like you can in internal.
Yeah. But, not creating a normal map from a high poly model to be put on a similar shaped low poly object (like a fire hydrant). I mean take multiple high poly objects and creating a single image from them to be put on a single plane. There was a tutorial 5 years ago about making a panel with lots of detail. In the old BI it was simply selecting the objects in order and baking to an image that could later be applied as one image to a single plane. Like the wood crates as well. All that geometry can be baked to a single image to apply as an image to a plane. Thanks for your reply.
Another winner.
to the point..nice one!
the best video on baking. thanks alot
