Changing Start Frame and Offset of an Image Texture node with Eevee does not immediately update [it does on framechange though]
Open, Confirmed, LowPublic

Description

System Information
Operating system: Windows 10 RS6 Pro v1903 July 2019
Graphics card: NVIDIA GeForce 920M

Blender Version
Broken: Blender 2.81.16 (official release), and it was broken a long long time ago since 2.80, nobody reports it.

Short description of error
Start Frame and Offset of an Image Texture Node don't work with Eevee (Material Preview or Rendered), but it works with Cycles.

Exact steps for others to reproduce the error



  • Add an Image Texture Node.
  • Open a movie (I'm sorry, I cannot pack the video).
  • Change the Frames into 100 or something like that, don't leave it to 1.
  • Switch to Material Preview in Eevee.
  • Try to change the Start Frame or Offset of the Image Texture Node, now see that it doesn't work.

Edit (optional):

  • Open any music video in your computer.
  • It's possible that it appears very black because the beginning of the video is black and it seems impossible to solve it.
  • Never forget to change the Frames to 100 or something, then move the Current Frame to check the video animation.

Cannot reproduce this [working relaibly here -- unless you set the offset to something that can then not be found in the sequence/movie...]

So in order to really reproduce, please provide a .blend file and an movie you can share, with exact setting for offset/start frame that are not working for you...

It doesn't work with my computer, whatever the Offset and Start Frame, it never never work whatever their values.

I updated the Screenshot and the .blend file, but the problem is I cannot upload the video as an attachment, so you cannot download it. But you can use any video.

Used your video in your file:

Step 4: You cannot use Start Frame or Offset due to the bug.

Yes I can. This is what I get with an offset of 50 (notice the video is really offset):


This is what I get with an offset of 0:

(only thing I have to do after specifying the offset in the node is to change the frame -- via timeline or shortcut)

  • What exactly do you mean by "cannot use Start Frame or Offset" or "now see that it doesn't work"?
  • What are you seeing whit an offset of 50?

Please play this video, it's not an image.
Here is a video I took with my phone, I'm sorry I don't know to use a video screen capturer.

Changing the frame is refreshing the video with the specified Offset. Thanks, I've never knew that because it 50% solve the problem. But anyway there's always a bug in the video above. But changing the Offset doesn't refresh the video.

OK, the immediate update when changing it on the node could be considered a bug [with lower priority].
