Thank you for the additional info. I will take a look at what you sent when I have a chance. Don't know what you mean by a "sketch"?

Also, I am not a student, I work for a nonprofit creating materials to support their educational program.

Thank you I will give that a try!

Hi Dr Sassi,

Using RS Environment, we are animating the Emission Color and thickness using Camera under Ray contribution of fog to simulate morning fog to clear daylight. After looking this up on the internet and trying different render setting we we can not eliminate a flickering effect in output renders when playing them back.
The color will say even then will jump fairly dramatically from one frame to the next. You can see in the image I have done a split screen of 2 consecutive frames. I have uploaded a striped down project and one material texture needed to duplicate the issue. Do you know anything that might eliminate this drastic jump in color from frame to frame?

If you render from this project starting at frame 110, you should see the issue by frame 128.

Thanks Mark

Thank you!

Do you know how long I have been searching for fog and cloud tutorials! I have been looking for info on this for probably 2 years, this is the best tutorial I have seen and never came up in my searches.
They need to add Fog and Cloud to the tutorial name or at least the keywords!

You saved the day once again!

Thank you, Dr Sassi!

Wondering if there is a way to have the fog extend outside the bounds of the spline so we don't see the hard edge of the shape?

Hi Dr Sassi,

We would like to get fog to swirl. We have tried using a spline with Volume Builder but can not seem to incorporate a noise to give it organic randomness.

Here is a link to the project, https://drive.google.com/file/d/1WKM7pz9hFsHSPOXrWQ1s-vms8iqUhkz8/view?usp=share_link

Please advise.

Thank you

Hi Dr Sassi,

I have tracked footage in C4d, and created a background from the footage and all is working correctly except I need the tracked footage to start later, so I thought I would set the "Start Offset to the number of frames I need and move the Solved camera keyframes to the same offset, but the video background will only start on frame 0 even though I have the offset set to 15.

Any idea what might be going on? I would upload the project but the footage is too big.

Thanks, Mark

Thank you! It works perfectly.
Also, thanks for the information about the image size, it does help to know that they can be wider.

Hi Dr Sassi,

I am trying to use the Playing Cards from the asset browser and am having trouble. I think I understand how this is supposed to work, I can go into the material and activate the card I wish to show, So I set the count to 5 and select the cards to show in the materials "Multi Shader" it looks correct in the work window but when rendering for Redshift only the Joker is rendered on all 5 cards. Is there something I can do to get this to work? I am also adding a random effector.

Also, why is attaching an image so limited here? 500x500 is so small! Seems like it should be a file size limit, not a dimension limit.

Thanks, Mark!

I am getting out-of-memory errors constantly now. This happens when rendering, seems to happen at about 120 frames into the render revert time. Very frustrating. I think it is the FOG in the RS Environment I am using.
