Hurray! I found the answer. Bear with me while I attempt to explain what is going on. It ended up being a scaling issue with the 3D models inside of E3D. I am including an image so it will be easier to understand. The smaller token (the one on the right) is a new model.

Top Panel: In this image there are two tokens. The token with the arrow pointing to it is the original model as created by the 3D modeler in my department. When importing and leaving the scale at 100%and turning on “normalize size” it is massive.

Bottom Panel: When you turn off “normalize size” (for the original token model), you can see that the scale becomes tiny.

The issue was the scale of the original model. I did not think anything of this when originally creating my scene since 3D models are vector based objects. I just shrunk the “normalized size” down to 4%. Conversely, the “non-normalized size” would have to be scaled up past 250% to be in scale with everything else (not shown) in my scene.

And this was the problem. Ae was using all of my vRAM attempting to deal with the scale of the tokens for some reason. I went back to my modeler and had him export the tokens again. First he upscaled the object 261%, which put it at 100% (non-normalized size) in my E3D scene. He then used a self-made script to reset all aspects of the object to zero, and exported a new .obj for me. This reset the token to a perfect 100% for me.

I ran a series of renders over the weekend and none of them “failed”. My RAM sat at around 50% usage (where it should be) and the RAM cleared after each shot rendered (like it should). So there you go. When working with E3D, keep an eye on the model sizes in your shots, they can kill your vRAM and cause you to have “failed” renders.

Hello Cassius.

Thanks for your reply. I did not know that E3D uses vRAM. Is there a way (if you know of one) to verify what my vRAM is on my machine or any way to optimize it so I don’t encounter this “failure” issue? I have not yet just tried rendering out the E3D elements to see if they are the culprits in this. But I will be attempting that tonight.

Dave (the post above yours) suggested that I just kick out background, main area, and overlay comps and compile them in Premiere. If I could not find a solution to this, I was just going to do that. I am just OCD in my shots and I like to have them all together so I don’t have to add layers in Pr if I don’t have to.

Thanks for you thoughts.

Thanks for the reply, Dave.

I have not had a problem in the past with mixing 3D and 2D layers in the same shot. Below is a link to one of my previous video using not only 3D and 2D images, but baked in animation out of E3D. This is why I am so confused. I did not encounter this “fail” issue in any of the shots I created for that video. And some of the shots in there are 2+ minutes long with just as many overlays.

I do think you are correct on doing pre-renders. I have a feeling that will be the only solution to this issue. I edit and compile in Premiere anyway, so it is not a problem to do. My OCD just likes to have everything in the one shot. LOL. I will probably be kicking out BG, main, and overlay renders and just put them together in Pr.
