Texture baking prototype

maru:
I think this is a typical use:
Though I have never used it...

juang3d:
It's also used to translate one set of textures baked into one UV set to a second and different UV Set without having to "re-paint" the texture, it's really useful.

Cheers.

romullus:
You're talking about projection modifier, but that has little to do with Corona.

pokoy:
From back then when I was baking at work I remember that having these channels was very useful for realtime etc:

- complete map
- diffuse
- direct light
- shadow
- AO
- object ID didn't play a role for us but would be important

Now since direct shading and shadows aren't easily separated in Corona this might be impossible.

Another useful idea would be to map any material property (let'say IOR value or glossiness values) to a grayscale value, at least I'd know why it would be useful to me.

We only had limited usage of baking and it's really long ago, so keep in mind my knowledge is basic.

Nope, I'm talking about having a diffuse map with one type of UV in channel 1, and inthe same geometry, in channel 2 having the new UV layout made by the modeler, now think that you have all the character with all the textures ready, but all the UV layout has changed, you have two options, or you work again in the textures to adapt them to the new UV Layout or you project Channel 1 texture in Channel 2 UV Layout, and you have the new texture perfectly baked and ready to be used, and this applies for a variety of things you can do at the same time, like extracting different maps or whatever other thing.

You can do this with scanline (as long as scanline stays alive), but it's sampling technology it's not good at all, and if you have an specific material like the Corona material you won't be able to do it, so you have to convert all the materials, make the texture reprojection from Ch1 to Ch2 and reapply oyour materials again, so having this inside corona is good, you save a lot of time.

Cheers!
