scratch marks when use 3D Solid

[Guest]

1.First I go to 3D Track in Video.
2.Then I add Solid in 3D.
3. I copy and past layer 3D.
4. I add Stroke in 1 Layer 3D.
5. Then happen like  striped, marking , scratch marks , a lot of little pixel .
6. All of that annoy me and when I move it I want to make a 2 Line in 1 Layer solid but the Line is scratch marks.
7. So I go to do a loop with add Solid in 3D everytime and when I render It take so long Time.
8. In 1 minute video I add 3D Solid about 40 Layer the Time render Export is 2 Hour .
*** at the first when i use After Effect like 5 mount ago I can Copy and paste Layer of solid and doesn't have scratch marks and I use only 1 solid 3D layer and copy paste is very easy and the render Export of time is shorter than this time .  #Adobe #scratchmarksinAE
I have no Idea what to do next I hop people come to see my Topic Thankyou.

Hi @Deleted User, 

This sounds like a coplanar issue -- meaning that the video and solid layers are on the same plane so its causing "tearing." The solution to that is either very small move (e.g. in Y) to separate the layers slightly or to set their opacity to around 97%  (The semi-opacity pipe handled that better at present). 

For your 2 hour render issue:

• what version of AE are you on?
• which renderer are you using, Classic, Advanced 3D, or C4D?
• what are your render and shadow settings at? You can check this by using the 3D renderer dropdown at the bottom of your comp window. What are the numbers they are set to?
•  what are your 40 layers consist of? 
• what codec are you trying to export to?
• Can you try exporting from the Beta app? 

Thanks so much for the intel,

Dacia

  Answer  Adobe After Effects 2023

Answer  Ahhh I get this at hte first I chose 3D and it okay to copy ans paste but I change to 4D and my video and layer solid is scratch marks  , That is the cause of the error. Well, it was my mistake for not checking. And Thank you "ขอบคุณครับ" DaciaSaenz, AE Engineering Team

• what are your render and shadow settings at? You can check this by using the 3D renderer dropdown at the bottom of your comp window. What are the numbers they are set to?

Answer  And when I change back at 4D to 3D , it take time render Export process shorter than 4D. Thankyou

•  what are your 40 layers consist of? 

Answer  40 Layer for make a line in Solid Layer of  3D track . at 4D I connot copy and paste but now I change back to 3D , Now it is very okay.

• what codec are you trying to export to?

Answer  I try to export to H.264 .

• Can you try exporting from the Beta app? 

Answer  I didn't try before.

Hop everyone get the answer with my mistake.
