Raymond Chua Posted April 20, 2009 Share Posted April 20, 2009 Hi all, How are you guys? I been trying to do a tornado on H. I been tweaking it for weeks and I still can't get it to look right. So maybe someone can look at my scene file and give me some ideas on where to improve? I have attached the render images and scene file. The images look horrible and I been trying to get it right but no avail. Thanks! regards, Ray tornado_merge_29_changeTornadoShader.hipnc Quote Link to comment Share on other sites More sharing options...
Starrider Posted April 21, 2009 Share Posted April 21, 2009 Check out 3dbuzz, there are some free tornado tutorials (Houdini 6 but should be helpful anyway). Quote Link to comment Share on other sites More sharing options...

Hi there, thanks for the reply. I have tried the tutorials at 3d buzz but it is not giving me the look i want. I would like to get a smoky details look. I know volume shader can achieve the quality, but i wish to see if i can get it done in particles using sprite shader since it is faster.

Is it possible to achieve something like this using sprites and vex surface SHOP? I have been playing with sprites' sizes, number of particles birth and the noise and color on the SHOP but still can't get that. This is a test achieve in volume shader. Something that look like this using sprites? Thanks. Quote Link to comment Share on other sites More sharing options...
Sayden Posted April 21, 2009 Share Posted April 21, 2009 I have a little crazy idea Have you tried to birth particles from the tunnel? Pointing inverse of the vector direction of each one with sprite rendering too. Quote Link to comment Share on other sites More sharing options...

I think you'd need so many sprites overlapping and shadowing each other that you're really just creating a Volume. Quote Link to comment Share on other sites More sharing options...

Personally, have you face this kind of issue before? And what do you end up doing most of the time to solve it? Quote Link to comment Share on other sites More sharing options...
