lights in smoke

Morning!

Just checking, I assume the only way to remove these flickering estimated lights is to render in raytrace? The explosion gets bigger everyday :smile:

Thanks

Holy mother of rockets in the jungle! I think this is the light cache though - if you get voxel-sized artifacts, try with less speedup or without light cache at all.

Wow, that looks cool, man!

Thanks! Yea I think I rendered this version with lightcache at about 0.1 or so. Shall try it off :slight_smile: The final video should look cool, nice personal project when I got time in between real work!

Did a quick render, light cache off worked :slight_smile:

Niiice! There are some black edges on the smoke at about 0:10 - do you use a custom curve or geometry mode? Also the flying debris around that time don’t leave trails since they are solids - sources would take care to create a continuous trail when emitting from particles, but with geometries it’s still on the todo list..

Nice, cool sim!

I feel the animation is a bit ā€œsmall scaleā€. Doing the animation slower, with only 25-50% of the height on the initial lift would create a better ā€œscaleā€ for a huge ass rocket. ^^ Especially with the scale of the explosion which is nice. :slight_smile:

Yep, that will be the next thing.. re-do the animation :smile:

Hmm, if RGB is involved, I think I know that the black edges are caused by - the grid is filled with black color at startup, so the advection must take special care of not allowing this to mix with the actual color from the sources. Are you using multipass? Do you render with Spherical or Linear sampler?

Morning, it is using Multi-pass and spherical sampler :slight_smile:

Hey,

Do the black edges still appear with Linear? This might introduce some grid artifacts though, since the camera view is aligned with the grid axis, but it might shed some light on where do we start debugging.

I shall try and look later today at some point… I really don’t like the linear sampler though, always switch to spherical :smile:
