Texture baking

[MaTtY631990]

Is texture baking possible with unbiased rendering engines. I know that real time game engines are to have used, but this could be incredible for animations that involve camera flythroughs for interior scenes that have many frames.

I think it should be possible.
You can read from an uv texture to know which color must reflect etc.
Also should it be possible to write into an uv, respectively an image.

Thanks for the reply. If this could be implemented in octane render it could save time for the really long renders where their is no geometry movement.

Hey,

The problem is that you can only bake diffuse as its non-directional.
Since unbiased engines have glossy, specular, transmission, SSS, etc,which are all directional reflections.
They cannot be baked, and the use of an unbiased engine for this purpose is not worth it.
You should use a specialized baking tools (eg a lightmapper used mostly for games) instead, using an algorithm like radiosity...

Ok, thanks for the information.

I hear this over and over as an explanation why texture baking can't be done. But I still don't see what the actual problem is. Specular/reflection is much less computationally expensive than calculating the while lighting solution every frame, so having even having just the diffuse is a huge benefit. Game-oriented lightmappers don't do nearly as good a job as Octane does with lighting.

I`m really surprised about your answer, radiance.
Why do you say "the use of an unbiased engine for this purpose is not worth it".
I think this is a big mistake.
Or do I understand it wrong? it is not possible from a technical point of view?
Or you (or the team) doesn`t consider this to be an useful feature?
Which of these 2 possibilities?
I don`t wanna sound mean when I ask this. I`m just totally surprised.
I think it will be better to give the artist the tools and 100% they will find use for them.
Many times an "technical or analytical" way of thinking does not lead to the same results compared to an "artistically" way of thinking.
Maybe I don`t mind the reflections. or maybe i don`t mind the shadows. or maybe i can build a lighting rig that will be special for that bake.
What do you think?
Do we have a chance to bake textures in Octane?
If this is not possible because there are technical limitations in Octane, then it`s fine. I will never ask again about this feature.
cheers,

Radiance answer is more then one year old.
Texture baking would be brilliant.

[Goldorak]

Yes it would refracty

I think something already clearly said,

"The problem is that you can only bake diffuse as its non-directional.

why do You still lift up this topic? Doesn't get the answer? read again =p 'cos now it sounds like this:

Q: CAN WE USE LENS of 50MM F1.4 INSTEAD TO HIT NAILS? ..
A: maybe You can but it's expensive, maybe You would instead better to buy a real hamer?
Q: well, but I would like to use the lens instead, it would be nice..

/dead end.. =)))
