Help Distance Fields not working

[josemendez]

Thanks for your answer Jose.
I have resolved it by using .blend file instead of .fbx, I still don't know why it doesn't work using fbx.
Anyway, now everything is up and running, except that I see that the fluid doesn't completely fill the empty space within my glass.

Scene view (I enabled convex just for previewing the collider)


Game view


See that there is empty unfilled spaces at the bottom and on the left and right of the glass.
I have tried modifying the material fluid, regenerating distance fields using any parameters, changing the radius of the particles, but nothing could fill those empty spaces.
Is there any solution to this?

Hi,

Probably the scale at which the mesh was exported in .blend was larger than the one used by .fbx.

Particles are rendered as ellipsoids that follow the fluid's isosurface, but collision detection is performed using spheres (with the ellipsoid's larger radius) for performance reasons.

You can:
- tweak the collider's "thickness", using a negative value to let the particles go into the collider a bit
- slightly increase the ParticleRenderer's "radius scale" a bit so that particles are drawn larger than they are.
- Increase the fluid's resolution (so that particles are smaller, the gap will reduce).

All three can be used at the same time. #1 and #2 do not affect performance in any way, #3 incurs some cost (as more particles will be used for the same volume of fluid).
