    Hi Andy,

    With the use of Instances as much as possible, because it has a significant effect in reducing the file size, one of the methods used is to render the scene in pieces and assemble the renderings in Photoshop or other programs. If you have several shots, you could in each scene keep only the visible things on the camera and delete everything else. You could also use the Polygon Reduction tool, in addition to some tips related to lighting and materials such as:

    • Check which material effects are computationally cheap vs costly as caustic or detailing displacement materials and use the cheap ones as much as possible if the costly ones are not significantly better.
    • Simplify lighting complexity as much as possible and prevent emissive surfaces from being blocked too closely by other geometry.
    • Consider faking volumetrics if possible and consider whether they’re worth it for the scene.

    I hope this is useful to you.

  • Hi Tom,

    I don’t have a way to make the process more evident, as you stated, and I rule out the existence of this because of the diversity of shapes and sources of spline each time, and as one of Maxon’s experts said in answer to a question related to this (I have no “one-size-fits-all” suggestion), but there are some helpful tricks, including using Mospline, because it gives you more control of the whole setup as the number of points and other things, including also using the hierarchy feature in the Extrude tool, which is useful when you have several splines so that you can turn them into one polygon with a clean mesh. I have put a video below explaining that. Also, one of the tricks is to use the surrounding spline to create the polygon and then use the inner lines to create the islands. As in the tutorial below, I also suggest you to use Extrude in the 2024 version because they have made performance improvements.

    I hope this is useful to you

    They said on the Maxon website that using Brute Force will solve the flickering light problem, so we have to keep that and go to change the light parameters. I don’t know what’s the Falloff curve value for the spot. We should set the value to zero because with increasing values the light intensity will decrease faster between the center and the outer border of the spot cone. Are there other lights in the scene? Because if a light is visible, it will cast shadows from other lights.

    Also, you could post your file here or email me so I can check it for you.

    Amazing! I worked on your file yesterday for several hours to fix it, but I could not radically solve the problem. I just reduced the overlap, so I left the matter to return to it later. Then I now saw your post. It was a smart move on your part. I congratulate you on that. What is strange is that I previously changed the height in the cloner, but did not occur to me to change the rotation value. In the attached screenshot, in the red box is the rotation value that you changed so that anyone who faces such a problem will know how to solve it. In the yellow box, I changed the height value slightly to a negative value to show that the book has several pages to give a realistic look.

    Thank you very much for sharing the solution and file with us.

    The same principle. I think the cause of the flickering is that the scene doesn’t have enough sample rays, especially since you are not using the light volume on an opaque model. So with RedShift, In the GI settings set both Primary and Secondary engines to “brute force” and increased the brute force GI rays from 16 to 512.

    I hope this helps you.

    Hi Alex,

    If you zoom in on the tip of the cone, you will find a distortion due to weak resolution, and as the light moves, that distortion becomes like a flickering, as happened to you. I don’t know, perhaps the reason for that is that the calculation of light and shadow is low with volumetric light. I think that to control that, you have to convert the shadow to Shadow Map, you will then find that the resolution is only 250. Raise it to the maximum possible value. The same applies to the Sample Radius, you will find it 5, raise it also to the maximum possible value (you could lower these two values ​​slightly from the maximum value if this affects your rendering speed). I hope this is helpful for you.

  • Hi Nils,

    I hope you could present the problem in another way by explaining the goal you want to achieve. Perhaps someone here could suggest another strategy better for your purpose.

    Hi Mikhail,

    Some problems occur with tracking due to the source of the video, the way it was shot, and the ratio between the height and width of the frames. You may be able to overcome this by using Lens Distortion profile. I have put a link below that explains how to create this. I hope this will help you.
