display a dynamic change process of data on the terrain by using decals

[sun.jinglin]

Hello, I want to display a dynamic change process of data on the terrain by using decals. I want to play an animation. Can this decal be realized

The decal is the first choice, but can the decal be set up? If not, is there any recommended method?

Thank you for your help

Hello,

As I understand you want to create something like a heat map over a terrain? Please, see the attached image for reference.

Decals weren't designed to display some dynamic changes and they will produce artifacts with big scenes.

But there's two possible approaches:

1. Using MeshDynamic instead of Decal. You can simulate growth and/or shape changing with plain mesh via code. Check our sample in UnigineScript\Objects\dynamic_00
2. Changing texture in the decal or mesh material. A suitable sample is available in the C++ API\Render\Textures

Please, give me more info on the task if I misunderstood you.

Thanks.
