After I saw that amazing tutorial of BiFrost from Maya. I told myself as soon as it comes out, I want to play with that amazing feature. Now here is my issue:
I've a bottle in which I want to create fluid and as soon as it rotates the fluid shall drop out the bottle.
My problem is that the collider isn't working. I added my Bottle as a Collider to my Bifrost emiter which is in this case a Cylinder.
As you can see Bifrost is pushing the liquid through my bottle and is ignoring the Collider Tag.
Any Ideas what I'm doing wrong?
Hello,
i´m normally a Softimage User but had a few month experience with NAIAD, what is now implented in Bifröst.
Don´t know what is the problem, maybe some tips:
1.) Found out that collider objects has to be Polygon-Objects and not Nurbs.
2.)Check out in the bifrostLiquidContainer under "Resolution" that your "MasterVoxelSize" isn´t to big.
Try to decrease carefully (!) the Master Voxel Size. Per default it is set to 0.5
If your bottle is 10 Maya Units heigh then 0.5 will work well to fill up your bottle.
If your bottel has no thickness set the collision to "shell" and play with the Thickness-Value.
The MasterVoxelSize defines a 3D-Grid in Space. If this grid is to big the colliding objects will not be very accurate calculate or will be ignored.
There are many other aspects for the MasterVoxelSize.
Very helpful is the old free NAIAD-Tutorial on Youtube from Farid you can see here:
I don´t know in which chapter it is, but in one of them he is explaining the workflow beetween Master Voxel Sizes and the calculation process for the particles and why sometimes particles make some strange things.
I think many of these informations are identical to Bifröst and can translate to them.
Sorry for bad english.
