How to achieve an effect of moving arrows in 3D environment?
I have attached below a screenshot in which a series of arrows are made visible after acquiring the target, however the arrows begin to move along a path indicating the direction of flow. Is this effect achieved by using a GIF as a 3D Image or TML-Text is used on that 3D Image.
one possible option, I know, is to use a shader /define in TML text widget and set the shader definition to the shader property of surface of / Model or ModelItem widget // also to 3DImage
Here is a post where this functionality was discuss. In the post also shown the setting as static property but there is also an example showing how to change the x, y property of the shader definition via slider- so this will - simulate some movement of the texture around the x, or y axis.

Here is also an additional post "" which demonstrates more advance techniques - where the shader should simulate texture flow. The principle is the same (for example the same principle to move an arrow in a particular direction, X or Y)
In case that you have some loops then you can split you model to different modelitems where you will apply different X and Y movements
In the mentioned post there are different pipes compoents / each pipe component is a different widget - modelItem widget . For each component there I used a different movement direction / but it depends also on the position of the components. Here in the example the movement is not only in a plane but in all direction in the 3d space Simulate Fluid Flow
Demo model is also provided where you can test it.
