[Max] I need help! / i need a diffuser.

« on: 2014-07-20, 12:44:53 »

Hello,

i'm trying to mimic a diffusing sheet of cloth, like the one the a box light has. I tried using translucency, but it seems it doesn't work, at least for a plane with no with.
I tried using noise for opacity, to mimic the cloth effect, but it doesn't work as i expect it to.

Does anyone has any advice for me regarding this matter?

Thank you.

[Max] I need help! / Help with daylight system

« on: 2014-04-26, 04:18:53 »

Hello,

i am trying to render a nigh time shoot, an outside scene in the desert.  I have about 4 square km area, which has track illuminated by light poles, and i want to get around 7-8 o'clock in the evening. But, with daylight system, and corona sun activated, no matter what hour or position i put the widget on, i get the same light intensity. Can anyone help me out with this? How do you set up a outdoor night scene?

Thank you.

Gallery / The glass project

« on: 2013-11-26, 12:39:09 »

Hello,
i intend to use this tread to learn trough a project.
I need to understand the following:

1. Geometry.
How does one models the liquid in the glass liquid scenario? I know i have to separate the liquid from the glass, and i have them both enclosed, normals facing outward, with a small 1 um gap between the top surfaces. Is this how to do it?

2. Is absorption working correctly ?

3. What are the correct rendering setting to be used for this scenario?

4. What are the correct rendering setting to be used for this scenario in order to have caustics?

i attached 3 renderings. the floor is the same glass as the other glass objects, and there's a background in the back with a hdr emission. Maybe s just me, but i don's think i see any caustics there. I'm rendering right now with PT+PT, but still, no caustics.

Hi,
I want to ask if model resolution counts in corona. It's is better to have a hires bottle of 5.000.000 polygons or a 20.000 ply bottle will be ok?
