Title: Corona doesn't update geometry of BLOBMESH
Post by: rozpustelnik on 2018-06-29, 16:30:18

Scanline does update the blobmesh geometry - rendering is similar to what is seen in viewport. Corona doesn't. Created mesh is wrong.

Hi rozpustelnik,

thanks for submitting the report. We've been able to reproduce the issue and will look into it.

Thank you for your patience

Has it been adressed yet?

Current status is that it's reported in our internal tracker. I think the Blobmesh object is pretty exotic (?) so it probably won't be high priority.

Well, it is not exotic if one use it together with particle flow to mesh particles into objects - imagine water splash.

Not sure this will work but as a workaround for the time being, will a TurnToMesh modifier on top help?

If it turns particles 1 to 1 into mesh then not really. Blobmesh is a specific object/modifier that has some parameters regarding mesh appearance, so when for example two particles are close to each other (treshold parameter) blobmesh will create one bigger (and particle to particle interpolated) mesh in their place. It's ideal for creating water splashes in cheap and easy way, without the need of running the simulation in 3rd party software.

But Blobmesh is a mesh, it actually doesn't change anything. My thought was that if Blobmesh doesn't send the proper notifications to the system maybe a TurnToMesh modifier added on top would successfully trigger an update notification. It wouldn't change anything, just help if it works.
If you're talking about PFlow than I'm not sure it can be added as a modifier on top... It would only work on standard particle systems I guess.

Try to use the Compound Object "Mesher". It works on a pr frame basis.

@pokoy  @PROH  Thanks! Will try.
