I hadn't even noticed that spline rendering was in already, nice! Cool update (the chemtrails are cool, too ;))

What both spline rendering and my cylinder substitute are missing, though, is the interaction with the fog medium. Lasers are invisible per se, just passing through "fog" makes them visible, so a noisy fog just does that. I can fake it with opacity noise in the (light) material.

or you could model a laser,
but note, since light source is "hard to find" & experimental bidir VCM engine is no longer available (+ I'm not aware, nor have I experimented to check, if there's any other new engine/tech in Corona for such cases), I'd expect "noise & long gone days"

For now I am going with thin cylinders with a lightmaterial.
Although I am not worried about render times. I won't be the one rendering it ;)

We already had a couple of Q's about this here:
 Spot light beam angle and CoronaLight Directionality

Do as advised by TomG, there's no other way (for now).

Thanks for the links.
So there is nothing but to wait and wonder.

Have you tried passing it through a hole after it is set to 100% directionality?

To my surprise this did not help/work either.

[C4D] Bug Reporting / 100% light directionality isn't that

I have an area disc light with 100% directionality, but the light still disperses conically - otherwise it would stay parallel and just illuminate the cylinder cap.
Bad for laser effects in fog.

[C4D] I need help! / Re: How the hell do I use the Pattern?!

Hi Forum,

Having a go at the Pattern but can not work it out!? I am tired so this does not help but will there be a C4D tutorial soon? Thanks :-) John

- Create a landscape object. This will be the base object to distribute the pattern on. Each base object needs proper UVs. No UVs, no fun. No good UVs, very little fun.

- Create a torus. This will be our sophisticated pattern. The size of the torus does not matter. Really. Size does not matter! At least now.

- Create a Corona Pattern object.

- Create some light, because we will now switch the IR on. You cannot see the effect in the viewport without rendering! Make Corona your active renderer, if this is not the case anyway.

- Switch the IR on already! You already did that? Sorry.

- Make the pattern object a child of the landscape and the torus a child of the pattern object. Whatever you see won't be pretty ;)

- Select the pattern object in the Objects Manager. Click on "Fit in Object Space" (just to make sure, the pattern object already adjusted that when you set up the hierarchy) and click on XZ for "UV Plane". Your torus, by default, "lies" in the XZ plane with Y pointing "up". The setting needs to match that.

- Still not nice? Yeah. Click on "Render base object", now you will see the landscape at least.

- Let us finally(!) create a pattern! Click on the UVW tab and set tiling U/V to 10 each. Or 11. This is your world and here you decide. And there are no mistakes, just happy little accidents. I stole that one, though.

- It is still not nice, but you should see the pattern. Go back to the Object tab. Set pattern height to 10%. There you are!

Play with the settings, changing the crop box size is a good start to see how to "weld" the pattern building blocks.


I downloaded an HDRi from the Cosmos Browser to use in my scene.  How do I make the image visible in the viewport in order to position it correctly?  Note - I am still using S24  with Corona version 8.  Thanks!

Until this annoying display issue is fixed, I will copy the HDRI over into a light material and use this one on an old fashioned Sky object.

I would like request to expose random seed parameter in clouds UI. Offset is good for animating cloud movement, but it kinda sucks for fast exploring of different clouds positions, since you need to drag the spinners a lot, or enter numeric values by hand to get substantially different clouds.

I could imagine a spherical map (for example a noise with a big scale) as a mask.

Would a seed parameter for the cloud creation make sense?

... and: in Max - if I read the forum there correctly - the clouds are visible in the viewport already, in C4D they are not - same reason as for the invisible HDRIs?

excellent result! I wonder, however, if in this case perhaps it was better to use Corona scatter

Scatter just ... scatters.
Pattern conforms the geometry to the underlying surface.

*** or change the render software

Good luck finding a recent one that still supports R16!

I would love to see a little video or manual on the new pattern modifier for settings like object space/world space or whole or crop box and xy, zy and xz. It seems all very straight forward though but I am getting all sorts of unpredictable results. An example file with some presets would also do.

Its so busy here at the office that I dare not try new features. The pattern modifier looks great though.

There is already a help article for Max, maybe it can be of use for you.

In your objects manager, click on View and uncheck Vertical Tags.

Thanks for that interesting tool!
What would be great now were some ready-made pattern building blocks for instant experimentation.
