Help Trying to make obi fluids work with terrain holes

[josemendez]

Hey guys! 
Im working on a construction sim which uses Digger pro for voxel terrain and it uses terrain holes when digging downwards and puts a mesh in the place of the hole. Now the problem is fluids does not seem to recognise that there are holes and flows as if there is no hole. 
I tested this with a plain scene with a new terrain and painted a hole and added an emitter on top, but it thinks there is no hole there.

Am I missing a setting somewhere or is there a workaround for this? Any leads will be appreciated.

Hi Abhishek,

Terrain holes are fully supported, they should work. Could you give a few more details about the problem? Specifically, you mentioned:

Digger pro for voxel terrain and it uses terrain holes when digging downwards and puts a mesh in the place of the hole.

I assume this digging/hole making is happening at runtime? If so, you'll need to manually update Obi's representation of the terrain (it isn't automatically updated every frame, just once when starting the simulation). This is done by calling:

Code:

((ObiTerrainShapeTracker)yourObiCollider.tracker).UpdateHeightData();

kind regards,
