[ANSWERED] how to make sure surface of sphere doesn't show

Eva

Hi:)I am presently working with different surfaces on a sphere, and for this I have currently used a texture on the sphere that is there simply so I can use other surfaces, that is photos and videos. The videos I need to start at a certain point, so I turn them on while fading in. This means, it is not the intention that I want to see the original texture. I just want to be able to fade in a video, that I start from the beginning. I want to be able to fade in and out different layers and most of the time, this work. My problem is presently that sometimes, if I turn the knob to fade in to quickly (and the knob also turns on a video, so it starts at the right time, the original texture of the ball shows for a split second. An now I want to ask, is there a work around to make sure this doesn't happen? I have tried to start the video a little earlier with some limit scale values on the nano controller, but I still sometimes have the problem.
Also, I found, that I can change the length of the video from 0 and in that way fade in, but then I cannot fade out with the same knob because it will also be connected with the video and the transition won't be smooth. I would like to be able to controll the timing of fade in so it is smooth with the music:)Does anyone have ideas, if it is clear what I mean? I also wonder if I need to make a new sphere texture in black, but Im not sure it will fix the problem.I hope this makes sense?
All the best

I think it appears every time there is no signal on the texture map input. I have tried with only two video player and a video mixer. If the two player are on off, I see the original texture of the 3D object. I have also tried two working solution:

1- the texture of the 3d object ist a black picture

2- add a background color and a multi mix actor after the video mixer.

I hope it helps

My advice is the same as @jfg, the original texture image file (jpeg or png) can be replaced with an image file filled with black color. All you would need to do is create a black image file with the same name and format in the same folder as the original image file. Then reimport the 3D sphere into the media bin.

However, if the background behind the sphere is not black you will then see the black texture. If you have a texture file that is already PNG you could add a full transparency to the texture image. With a transparent PNG file assigned to the 3D sphere you will be able to get it to disappear dependent on the parameters for showing back faces and lighting in the scene and if you have more than one 3d asset layered in the scene.

if you use a transparent .png picture you will need to set the "use alpha" input from the 3d player to "on" and the background color of the video mixer to transparent.

Could you also use a black rectangle from the shapes actor?

@jfg, @bonemap @CitizenJoeGreat,
Thanks that worked:) really nice!
