Being completely new to everything blender and 3d modelling i have run into an issue.
What i would like to achieve is making a 3d terrain model and being able to do some terrain analysis and visualisation using fluid simulation.
Using BlenderGIS i have made a 3d recreation of the terrain I would like to use, but when i try to incorporate this in a fluid simulation (using quick liquid) i just cant seem to get the fluid to collide with the 3d model that comes out of BlenderGIS.
I have tried to make the surface thickness way thicker, i have solidified the faces using edit mode, i have tried to use it as a guide instead of collision in the effector selection, and i have used the fractional obstacles with obstacle-fluid theshold to the max.
For some reason the fluid keeps passing through the terrain model.
I hope someone here could point me in the right direction.
I dont know if this is a common problem with objects created through blendergis? the way i use blendergis now is DEM raw data, and letting blendergis create the faces.
As a new user i cannot yet upload a file, but when i can i will add a blend file
