Vray Frame Buffer background image frame sequence

This seems like an obvious question, but is there a way to load an image sequence into the background of the frame buffer so when I move the play head in my maya scene the image gets updated with the correct frame? The maya native image plane has issues when the VFB is involved.

You could use an image plane as long as you have a background sequence you just set the image to play as a sequence on the image node, so frame 1 would be image_001.png and so on.

Yes, but the image plane seems to have issues with acescg exr’s while sending a png or light jpg sequence to the vfb from the maya image plane creates color issues.

Does the Color Space of the Image plane match the color space of the imported image? I’m getting correct results with either .exr, .jpg and .pngs.

It does with exr’s but did not seem to work with the PNG’s or JPG’s regardless of the color transform I pick in the file read node.
My initial question was about the VFB supporting image sequence advancing for it’s background image layer which sounds like a no. If there are any vray devs here maybe put this on the list? Sort of embarrassing to have a render viewer that can’t sync with the timeline of the host application.

Actually, you can do it with the Background layer by replacing the frame number with <frameNum>. It was in the docs all along.

Hello sir. Could you give an example how to use that tag on loading the file? I checked the documentation but there are no examples there also.

Tks so much!

Check the attached .gif. The filename of the sequence is img_0000.jpg, so I just replaced the numbers with <frameNum>. to get img_<frameNum>.jpg

Just tested this mehtod in maya.Is there any way to retime sequences with this method?
I was also looking into using Enviroment override + Background image but the footage we use is not cropped to the desired aspect ratio so when using “screen” i could not match the desired crop we would need.

Only this wildcard exists. You can always get some freeware to mass rename the images.

I actually got it to work with a background script job feeding the VFB with the FrameExtention of my image sequence at current frame. Works well enough
