Particles not showing up!

Hello!
I'm having trouble getting particles to show up in a composition.

How I have the composition set up is having my "MediaIn" node going to a "Camera3D" node, going to a "Merge3d" node, going to a "Renderer3D" node, then going to a "MediaOut" node.

My particles are created by a "pEmitter" node, which is connected to a "pRender" node, and that goes into the "Merge3D" node.

The particles appear when the "Merge3D" node is displayed in one of the viewers, however, is not seen when the "Render3D" is displayed in one of the viewers.

I'm not sure if another node is needed, or if there is a specific setting needed for the particles to appear.

In the "Renderer3D" node, I changed the "Renderer Type" to OpenGL Renderer as was suggested in a tutorial video by Blackmagic, but this did not solve the problem.

Any help would be awesome.

Thanks!

Are you certain your camera is pointed at the particles? Is there an ImagePlane in the camera that is occluding them? You don't mention a light; is Lighting turned off in your Renderer3D?

Typically, you wouldn't put your MediaIn directly into the camera unless you need to use the footage as an image plane. A more usual workflow would be to Merge the output of the Renderer3D over the footage. That way you'd get independent control over blur, color correction, etc of your particles.

Thanks Bryan! I was able to the particles back into Renderer3D.

For some reason when I would change the particle type to "line", the particles wouldn't show up. Other particles worked fine.

(in Resolve Studio 16 first beta on windows 10) i tried every type of Style in pEmitter, only Blob and Ngon worked. Point, Point Cluster, Line worked before the renderer, but not in it, Brush did absolutely nothing anywhere (probably some other reason for that, perhaps mentioned in the manual), and Bitmap caused an instant crash. i believe i have followed BMD's tutorial precisely, but they are using R15 and i am using R16.

The Line style creates vectors that the software renderer doesn't support. You should see a message to that effect in the Console: "warning - Line rendering is not supported by the Software Renderer." Switching to the GL renderer will probably cause them to appear.

Points and Point Clusters should work in both renderers, but remember that they're very tiny and don't respond to the Size control, so they may simply be hard to see. Try tuning on Proxy mode. That will force them to undersample, making them larger but blurry. That should at least verify that the pRender is working.

In Brush mode, you have to select one of the Brushes from the Brush combo box, which appears below the Gain slider. I believe its default value is "None."

Bitmap mode requires you to connect an image to the external input that appears when switching to that mode. It certainly shouldn't crash. Please submit that as a bug report in a separate thread, and we'll see if others experience the same thing (I don't have the beta installed at work, so I can't test immediately).

I wish we could get some feedback on this issue. I've followed the tutorial perfectly myself with the same result. No particles rendered

In the right viewer which should be the Camera3D view from the Merge3D node, make sure that the "Checker Underlay" is unchecked under the 3 dots menu. Also, make sure that you are using the OpenGL Renderer under the Render3D node.

All that already done. No particles rendered. I'm wondering if the problem is that I'm using "fusion composition clip" as my source clip instead of a real video clip. I think I'll try that, or maybe a solid color
turned into a compound clip.

That's weird that it's working for you. Practically the same node structure that I have. Could you possibly take a screen shot of your pemitter and prender node settings?

Here are my pEmitter settings.

Yep, I've got the same settings. No particles rendered.

If you can select the nodes in your Fusion comp, hit ctrl-c, then reply to this message and hit the "Code" button and click in-between the two code tags and paste the code you can post your node tree and I can copy it into Fusion and see if I see the issue.

As an update, I've gotten glob particles to render but would rather line or point. I've pasted code as you asked. Thanks for the help

I took a look at your nodes and the only real problem I saw was that you had the size of the particles too low, he had them set to .5 then tweaked the other settings below the main size setting. I didn't get them to look exactly the same as his with that size setting, so I would suggest maybe 3 or 4 for the size setting. I cannot see all of his settings so he might have a setup that causes the particles to show up better when he made the video or there might be a slight difference between Resolve 15 and 16. If you are still not seeing anything I am at a bit of a loss.

Thanks. I'll give that a look. I believe I changed the size because I switched to blob particles instead of line but I'll switch back and see if I can get them to show up.

I ran across what I think is the same issue via a BM YouTube tutorial. I was able to make the particles visible by updating the fixing the pEmitter / Style / Color settings. Color appears to be white but is at 1.0 for each component... if I change to something like 10, particles become very bright.

My post to other thread is here...

The Point style particles may entirely vanish if you're not viewing at 100% scale. They're only one pixel in diameter, so filtering can very easily make them invisible. The reason they show up when you turn up their brightness is simply because you're averaging a much larger number with the surrounding black pixels.

Thanks Bryan... these were line particles with the tutorial's values. Maybe the YouTube video tutorial is using a higher quality graphics/monitor setup allowing the particles to be seen or something. I'll keep that in mind.

Hi there !

I stumbled upon this topic because I was having trouble myself not seeing particles in the camera POV while I was able to see them in the other viewer. After tweaking around particle size, brightness, render node settings etc. unsuccessfully, I realized a bit by chance that the node that was activated in my viewer was the camera node. As soon as I activated the particle render node instead, all my particles apparead like magic while keeping the POV of the camera ! Hope this will help others...

Actually let me add that if the problem happens when you activate the render 3d node view, I found a workaround : I created a second merge3D node to link the render3d node, the particle render node and the previous merge3d node together... Work like a charm after that ! Maybe a bug in Davinci Resolve 16
