Render vehicle only

[wjie-gogogo]

Thanks for your great work!
I noticed that NeuRAD supports rendering only static background in

neurad-studio/nerfstudio/scripts/render.py

Line 738 in b7012ac

if actor_removal_time is not None:

, I want to know if there is a function or boolean to render moving objects only. If not, some advice to change the code will help me a lot！

I try to mask the origin image to train the moving object only.

At the same time, I set the background to black,which is [0,0,0]. In this way, when calculating the loss, the RGB loss will be 0.
However, the actual training result is more like a grayscale image (the red light has the color, but the yellow car body does not have color). As shown below, left is origin image, right is training eval image

So I would appreciate if there is an elegant way to train only dynamic vehicles or you can give me some advice.

Never mind !
I found the final render video has no problem!
