Why not making/using a LUT?
It works fine for Blender, even if render is done with Corona SA.



Troy J. Sobotka had done False Color Look for Blender's Cycles: Look Transform. Surely, you can too ;)

Don`t know if I undertood it.
Does it shows the real illuminance values on the surfaces ?

Hi, this was requested a few times already, and we are aware of the need for this. Any discussion about how exactly light analysis could be executed is welcome.

Nice to hear it and thanks for the quick response.

For me there are two important information, a numeric one which shows the real Lux on the surfaces and the pseudo color that is useful to quickly visualize contrast between areas.

It is important so we can match the rendered concept with what is going to look in real life, this way we can prevent an area to be over or under illuminated as well as comply with building codes requirement.

The pseudo color shows a degradee between a chosen range of values ex: 30 lux to 5000lux

Here are some examples:
Lux values  -  http://help.autodesk.com/cloudhelp/2016/ENU/3DSMax-Tutorial/images/GUID-67A4FE1A-0CD0-4F15-838B-60D3A9904503.png

This one is from 3dsMax, it creates a grid on the rendered image and shows the lux at each node. You can choose the grid density:

[Max] Feature Requests / Lighting Analysis Features

Hi,
First of all great rendering, I've been testing it for a while now and I`m probably changing from Vray to Corona anytime soon. I really makes my life easier with better results.

One thing that I would like to see is some integration with the Lighting analysis tool built in 3dsmax or maybe a pseudo color shader to show light intensity (LUX) on the surfaces.

This would be great for those working with lighting design or architects who want their rendered lighting to match the real world light levels of a built ambient.

Thanks

[Max] I need help! / Re: Missing the VFB side pannel
« on: 2016-06-10, 04:16:45 »
Duhhh !!
Sorry for that

Thanks

Hi everyone,
Suddenly my VFB side controls disappeared. I mean the color map and others. They are gone and I couldn`t figure out how to solve it.

Any clue here?
 

6
Didn`t work.

Keeps crashing. Don`t know what else to do.

Any idea here?

All the other renders do work fine Vray, mentalray

7
I tried it.
Now I`m trying it again but erasing every trace of max in my pc. I remember having some trouble to uninstall max 2013 ( I had to force the uninstall).

Maybe it's a related issue.


8
I reinstalled Corona
Activated a Demo License

But now it crashes Max when I open material editor and pick a Corona Material
Also, when trying to render it just freezes.

9
I just start max, Choose corona as render, Create a box , add material, add a corona light and render (perspective, no camera)

No warnings

by the way, it,s windows 7

Hi everyone, hope some of you can help me.

I`m experimenting with Corona for sometime now. By the way, it's amazing, congratulations.

But, let's go for my problem. I'm trying to setup corona on a new PC, so I can experiment with distributed render.
The problem is it's rendering a complete black screen and numbers of passes goes really fast.

The max scene has only a box and a light.
All the setup is in default.
I have experimented with light intensity - Nothing happens
If I change the color of Environment Corona does change the color in the VFB but no object appear.
Adding more objects also desnt work
Materials also does not show preview also.

I`m using Max 2016. The same in my other PC (where everything works just fine).
This PC has a Intel i7 2.93GHz
GPU Radeon HD 4350
8GB ddr3


Any clue on what is going on here?

11
After installation, how do I find it?

I`m using Max 2016

Thanks

[Max] Tutorials & Guides / Re: *Most wanted tutorial topics*
« on: 2015-10-03, 23:41:58 »
A bit complicated for me to grasp that concept at the moment, but i bookmarked this topic, so i come back at it later for sure :]

BTW, in your strawberry tutorial you used IOR at value 1.0 or just slightly above. Wouldn't be more physically correct to use higher IOR, like close to fresnel IOR values? Did you do that for performance reasons or there's something else?

Nope, i just did not find higher IOR values looking right. But i knew nothing has 1.0 IOR, so i tried to add at least some.

When i observed real strawberry, i found out that light doesn't bend and refracts inside that much, but at the same time, i did find that using translucency only made strawberries look too solid and not watery and juicy enough. So i added some refraction to the mix, yet i found out that when i increased refraction IOR, light bending was too significant and did not look like the real strawberry i was looking at :) So the only way to have still somewhat not completely solid, but also not oddly refractive strawberry was to use unrealistically low IOR :)

Amazing strawberry tutorials.
I`m still trying to figure out exactly the SSS but I think I`ll get there.
What about a strawberry cut in half with a texture mapping it, I`m trying to make it work but I`m not sure where to use the diffuse texture. Any idea?
