K-Myst or Psyclone?

#1

I’m wondering, can these K-Myst or Psyclone produce image similar to to this photo (sorry, I’m no good photographer…) where light pass tru the clouds with ray…

I would like to make a star shape cloud, with ray light pass tru the cloud…

how can we compare these two cloud shader… is Psyclone a shader?

thanks for any advice. :slight_smile:

Hi Loon,

I have Kmist and I really like it, it’s got very good documentation, very cool sample projects and it’s very stable.

I do not think you can make light rays pass through it (like with a smoker) but you could fake this with a star shaped object and the erroded shader.

I do not know anything about Psyclone (I think it might already be a UB though…)…

Hope that helps,
Ian

Afractal could do it easily with a glow light (with ray) Or you could just use sky (and clouds) images and do the same. Just shining a light (with ray enabled glow) through any clip-map will do this kind of volumetric light trick, so you don’t really need any additional plugins or shaders.
However, these kind of tricks can require a fair number of iterations of setup and test renders to get the right look. You can also do this sort of thing in post (in real time) and know the look is spot on (too many times an effect like this can be too subtle, two extreme or blown out highlights (flat) by the time you get it in the final comp.)

Here is a quickie of a light (with ray enabled glow) shining through a plane (clipmap)

Thanks WmH, :slight_smile: thats help alot

I was also thinking of using Light Projection map to do the tricks, that will need some hard work done in photoshop…

Is this something that you -must- do in 3D? I think you’ll have less heartache doing it with real imagery compositing it in AfterEffects. Unless you need to fly around it or something.

it’s just a still image, the problem is the cloud in star shape, I was thinking to do it in photoshop before, but the client might want to change the angle/perspective, for me 3D is the only way to do it… :slight_smile:

Psyclone generates a clip map. It’s not as elegant as I would like but that really due to the fact that we’re not simulating atmosphere.
