Pyro Smoke Dissolve

[nopopoch]

Hi Dr. Sassi,

I was trying to follow this tutorial the best that I could but I must have missed a step or two and cant figure it out. For some reason I'm getting smoke immediately before it is triggered. I am also unsure how they're getting such a clean fade off between the smoke dissipating and the object disappearing. The whole reason I was trying to copy this effect was actually to make something that look like a dissolving pill. I was surprised I couldn't find more tutorials on full volume dissolves. Thanks!

Here's my attempt:
Smoke_Dissolve_v001.c4d

Here is the video I was trying to follow:

Hi nopopoch,

Thanks for the file.

Inside the Igniter (Smoke) Vertex Map, the Invert was switched on. Box was suggested, Linear in this case needs to be in the opposite direction.

Sorry, I saw your file too late was in 2025.3.3
Mine below is in 2026.0. (Edit I got an alert when saving./edit)

CV4_2026_drs_25_PYsm_01.c4d

I have attached a transcript if you would like to go step by step.

Please let me know if there is any question about this set up. I'm happy to look in the morning into it.

All the best

As a side note
If dissolving is the target, perhaps this is an option:
