I’ve got a little issue with the replaceTexture puzzle.

I would like to have two buttons, to switch between playing a video and showing an image on an object.

Problem is that, as soon as I replace the map with the video, I can no longer switch back to the image, cause the map name doesnt exist anymore.

What can I do to fix this?

Use two materials that look the same, load video texture into one and replace materials.

Have to get back with this. This worked at first, but now it doesnt anymore and I dont know why.

Maybe because of the latest update?

I tried to debug this with a simple scene and pure puzzles. And it seems that after assigning the video material to the object, the other material gets deleted from the scene. Because after that happens the puzzle shows the material in red letters and in the dropdown it isnt anymore.

Sorry to push that issue again. Would need to get this fixed pretty soon. So would be great if someone of the devs could get back to me

Otherwise I would maybe need to create materials on runtime via javascript to workaround that issue.

Hi,
in Verge3D 3.3 we introduced a feature when materials being replaced by other materials are automatically cleaned up. If you need to preserve it, assign (in the loaded asset or dynamically, via Puzzle) to some other invisible or remote object. So I believe in your case the issue is with geo_video material being clean-up by Screen material.

Simply assign the test material on some invisible plane in your modeling tool and reexport.

Would you be able to show me (screenshots) of how you accomplished this? I’m looking to do the exact same thing. Possibly to swap a video texture with another video as well. I’m very new to this, and this has been a big stumbling block for something I’m looking to do. Any help would be appreciated. Thanks!

Hi,

you can check out the demo Video Texture if you’re using the Blender version.

I looked at the blender monitor/aquarium file. I was able to change the image texture to a video texture, but I was not able to replace the video texture with an image, or another video texture.

There were issues with video textures fixed in version 3.4 preview. You might give it a try. Here is a setup that works for me:
