Smoke: Testing Color controlled over TexUVW

[BeneZ]

Hello,
there is no official tutorial yet on this, but I tried to use also Smoke Color with TexUVW.

So as I understand, when I render this with TexUVW enabled
and for Rendering (geometric options) > I go for SMOKE COLOR "Texture" and check "Modulate"
then it should give me the Texture on the original coordinates, only that I could exchange this over time.

In my rough test it looks a bit different than using just RGB.
(when I use the same texture for RGB and compare how it looks when I use that texture as "texture")

For the start picture (using a sharp volume brush) I get a darker and unsharper result.

- Is that workflow correct or should I know anything else?

- Is it possible to blend between the setting RGB and the Setting "Texture" during rendering a sequence?

- checking "Modulate" with texture never made a difference...

- GPU seems currently not to work with this. right?

Thanks

Hey,

Your workflow is right, you just don't necessarily need to click Modulate. For example the smoke color - it can be based on some grid channel or texture, and if it is based on a grid channel, it could also be modulated by a texture, so this is what Modulate does. Check what the docs say about Modulate https://docs.chaosgroup.com/display/...er+Smoke+Color So this answers your other question - indeed you can blend between RGB and a Texture using the Modulate option.

Here you can find one official tutorial on TexUVW: https://docs.chaosgroup.com/display/...ing+Thin+Smoke

Here are a couple more official setups: https://youtu.be/mGAyh3uR89U?t=3061 (at minutes 51 and 54).

Lastly, indeed TexUVW is not implemented yet for V-Ray GPU. Cheers!
