Hello all,

I am starting to play around with the smoke tools and I have a nice wispy sim going that looks fine in openGL. I am having some trouble shading it though, using the wispy smoke material.

I have quite a small setting for my volume step size on my mantra rop, 0.05, which I think is quite high quality for the size of the smoke domain. When I render a test frame it comes out looking quite nice, but when I render the image sequence certain frames look fine and certain frames have a banding to them, almost like I dont have a high enough voxel res, but my low res sim was at 80 cubed and my upres sim is at 140, so I'm not sure whats going on.

See pics and hip file attached.

Could someone shed some light on this for me please?

Thanks!

Sorry the above images should be called ‘good_frame_1038’ and ‘bad frame_1041’ as they are frames 1038 and 1041 respectively (the sequence starting at 1001), just in case that was confusing anyone.

Thanks.

So no one has any clue huh?

Any developers in the house?

Hi,

On your /obj/upressmokeobject1 node try increasing the shading quality (render tab -> dicing tab - > shading quality). I increased it to a value of 2 and the problem went away.

Cheers

Tony

I agree that the default values for Shading Quality should be 2. Another thing I immediately increase in Deep Shadow Maps is the Pixel Samples. I will increase Pixel Samples to 2x2 right off and then increase to 3x3 before I consider increasing the resolution of the Deep Shadow map.
