DEV-thread - Blendigo v0.7 - material-editor-exporter

hi neepneep,
in fact meshes and materials get exported only once for animations. Only the objects are exported for each frame (some way more economic when you have big meshes).
Do you need animated meshes in your animation? Because currently only the animation on objects (loc, rot, scale) are exported by Blendigo

What type of animation do you need?

Yup, I am trying to animate a mesh via vertex keys. The scene is fairly simple - 10 frames in all and about 3 mb per xml. I managed to do a quick render of it by exporting it frame by frame which means Blendigo definitely can export vertex keys (check the zip for the animation.)

Can someone help me with the settings for milk in Blendigo v0.7t5_beta4?
I get colored liquids, but when I set the absorption to almost white the liquid gets transparent (with sss)

you should set higher SSS, in this case

absorbtion doesn't need to get whiter and whiter! It's a value, that tells you, in how many meters, the colour completely get's absorbet, so the values should be pretty high, n milk, I guess....
Also, blue gets absorbed fastest, as milk looks a tiny bit yellow...

Maybe, you should post an image and your current material

Ok, I searched a bit... These are render settings, used by mentalray... don't know, if the values do exactly the same as in indigo, but you can try

IOR = 1.3
absorption = 0.014 0.025 0.142
SSS = 7 12.2 19

(for these SSS values, you have to set this:
R 0.07 G 0.122 B 0.19 Gain 100 Try it

)

it´s a real quick render, I know.

I can't see your pics! They are red X's with white bg!
Use the new attachmentsystem for uploading pics

This would be more effective

sorry, I can see them

nice feature

hmmm... SSS seems to be wrong.
Press once onn the preview and get your Cursor away, then the colour should be inversed

Absorbtion looks good.
I'd say, you should extremelyy increase the gain in both values.
absorb. gain 300
SSS gain 10000

If you could give anything behind the glass, we could better see, how the milk looks like, than if you just have a white plain as floor...
either use a tiles-texture or a, say, diffuse primitive sphere behind it

(Primitives can be made, if you name the sphere "___.sphere")

I will give it a try.
Here is what I did since then. The values are from the scattering-new.pdf for Indigo 0.7t2.

looks better... but somewhat, if it just was the fat of the milk, without the rest...

Your scattering colour is back to front. click on the blue colour picker and move your mouse cursor away (someone already mentioned this) and it should change to a creamy colour. That's what you're looking for for the scattering. and change the gain to about 1000 for scattering too.

I've already said that

(And I mentioned this kinda-bug)

Now I understand

It´s rendering.
Here is what sss gain 1000 did:

at least, it now looks... intransparent

but it looks too yellowish...
