Fluid Rendering
 

Alright Guys

Having a bit of a problem with fluids, when I render the image out I have a degree of "Blockyness" with the fluid, as can be seen at the edges of the fluid in the following render.

Do I have to increase the resoliution on the fluid or its there another way?

Note - The render was rendered on "production quality"

Cheers

I've had the same problem.

You can increase the resolution of the fluid contianer but it wall also affect the dynamics of the simulation. In other words, the explosion will probably look different if you increase resolution.

I think that if you decrease the amount of fluid/second this will also help.

To be completely honest, I never did come up with a great solution to the blockiness.

There are some explosions and a meteor animation on my website. Check it out!

Just had a look on your site, nice work man.

Tried loads to ge it looking better, including doubling the resolution, this gives huge cashes and lot's and lot's of slowdown on My PC.

I'm going to atttempt to comp this into some footage of my city, hopefully.

I'll give the fluid/sec a go.

Cheers

Hiya,
You might be able to loose some of the blockyness by playing with the opactiy curve and the bias.

Currently I'm doing some fluids and haven't run into this problem, maybe because I'm using the texture opactiy. It may also be the temperature, it sometimes causes a sort of "streak".

Cheers for that, i've tried and tried adjusting temp, and the opacity curve but to no avail, Need to have another crack with it as I aint givin up!!

My theory is that if the explosion is happening really fast, the voxels will fill up completely inbetween each frame so that they always appear full (that's why the fluid is blocky) instead of filling up gradually and overflowing into the voxels around them. That's why I suggested decreasing the amount of fluid being released per second. Use less fluid and adjust your density curve.

Just a theory..
