Btw it should be a nice alternative if CoronaScatter could scatter based on pflow particles matrix.

Good to know, thank you.
I often use data operators, maybe it's that one.

Ondra ?

Hi,

I'm really impressed with last build speed increase !
However I can clearly see a color tint shift.
Even more strange is that it seems there is time shifting too.
It's a PFlow scene, don't know if it's related.

Here is a simple noisy test :

Edit :
Forget about the color shift, it appears only when viewing jpgs here on my mac, not in max or in browser.
But still strange, has jpeg saving changed ? A color profile thing or something ?

nothing about saving was changed, or could even be changed, because saving is done by 3dsmax, not corona ;)

Even when saved from the corona vfb ?
Do you have any idea regarding the time shifting ?

I think I found the "time shifting" culprit at wake up...
I use custom bokeh map, there was an offset issue that was resolved few builds before. Should be that.

Oh wait, it don't even work when I pick a single geometry...
Is this feature broken ?

Hi,

It appears that PFlow true instancing is not working with a scene I'm working on.

I use Shape Instancing with a group to load several instances, maybe it's not supported ?

Thanks for your help :)

Do you think it is possible do allow values bellow 0 romullus ?

IOR value lower than 1 in textures will now render as 1/value, so you can use LDR maps without using output manipulation. This is to improve compatibility with applications such as Substance Painter.

Isn't the same what Vray does?

I don't know what's V-Ray behaviour with textures as IOR, cause I only used to input direct values below 1.

Corona mtl don't allow this, so I tried with a corona color map plugged into the IOR slot, but I got weird results compared to what V-Ray does.

If you're using Corona version prior to v1.3, then plugging 0-1 ranged map into IOR doesn't make much sense. In v1.3 however it should behave same as Vray, AFAIK.

I am not sure what Vray does, but Corona does something strange indeed. A lens with IOR below 1 should not flip what is behind it upside down, and it does in Corona. I think setting it to 1/1,33=~0,75 does the same as setting it to 1,33.

I agree with you maru, that's exactly what I tried and it gave me same result as 1.33.

I use version 1.3

Hi,

I try to render air bubbles under sea surface, so I have to set the refract IOR below 1.
Corona mtl don't allow this, so I tried with a corona color map plugged into the IOR slot, but I got weird results compared to what V-Ray does.

Do you have any idea ?

Thanks,
