Double face?

That will work as well. Thanks!

Sometimes to minimise the post work I put the proper sky background in the scene as a CoronaLightMtl
I see now that the CoronaSun position does not reflect the physical position of the sun but rather serves to define the light direction (yes, that's the reality)
So, to get the sun visibility together with the Bloom and Glare effect I have to make the background transparent a little bit or to put the Corona Sphere light in front of the background
Just wondering if there are more options )

Unfortunately, that does not help

The only solution so far is making the object a bit transparent through Opacity map

Please advise!

Most of the time for vegetation we have to adjust the Output parameters (Output Amount, RGB offset, RGB level) of each bitmap in Multi/Sub-Object material at once
In this case we use the following script

You should try it )

I would love to understand more about the Directionality parameter.

If it's not linear is it possible to correlate it with the light beam angle of the real lights?

I attached the scene with 3 IES lights taken from the Philips lighting website:

My question is How to adjust the Corona lights to mimic the similar beam angles? Only by trials?
Any help will be appreciated

Not sure if I understand your question correctly, but I would say that directionality 1 = 90 degrees beam (the light shoots straight from the light object's normals - like laser).

Hi Maru,
Let me re-phrase my question.
How should I adjust the Directionality parameter to match the Beam Angle of 60 degrees from the light's technical specification? Will it be (1-60/90)?

Is it the linear dependence between the technical characteristic of the light source and CoronaLight parameter? Let's say setting the Directionality to 0,5 will be physically correct for 90 degrees beam angle?


In the latest daily it's possible to add only Corona Camera origin into the Distance Texture
Would you consider to add the Physical Camera as well?

The feature is very helpful, indeed

However, would you please update if Corona team is working on the issue about UVW center transform for Randomizer


Yes! Big big hope!

So hard to make the randomised tiled flooring with one not seamless texture


I have a simple test scene of the mesh with 4x4 square elements
Each element has planar UVW map and Gradient Ramp Map with Box Gradient Type
The topic and attached picture should explain everything

I would recommend to create the cable through the Loft or through the Sweep modifier and turn on their own Mapping

Also, as an option it's worth to try Interior Mapping Shader
Similar to this
I know there is one for VRay
But I'm not sure about Corona
