Sophie Posted March 24, 2018 Share Posted March 24, 2018 Hi there, This is the first time I'm positing it, so I hope everything is in the right place :). I've been watching the Jeff Wagner tutorials for flip fluids and I have a question about one of his examples. In the water rapids file, the fluid basically flows over the side of the terrain and out. I tried changing the velocity, but that doesn't seem to change anything. I also tried to make the fluid follow a curve with a velocity field, but this doesn't look natural at all. I was wondering if anyone can maybe explain why this happens and also if anyone knows how to fix this? Thanks. Quote Link to comment Share on other sites More sharing options...
StepbyStepVFX Posted March 24, 2018 Share Posted March 24, 2018 Hard to tell... have you checked the scale of your scene ? Maybe try to play with gravity, increasing it ? Quote Link to comment Share on other sites More sharing options...
Sophie Posted March 25, 2018 Author Share Posted March 25, 2018 @StepbyStepVFX Hi, I have tried playing with gravity and gas wind as well. Changing the gravity in Y only, only makes it flow down quicker. Playing with X and Z either doesn't help enough, or by the time it doesn't flow over one side anymore, it starts flowing over the other side :/. Could you maybe explain what the scale of the scene could have to do with this? Sorry if that is a bit of a silly question, but I am really new to fluids.

Noobini Posted March 26, 2018 Share Posted March 26, 2018 it's just a lump of rock acting as a deflector to me...it just works.. Quote Link to comment Share on other sites More sharing options...
Noobini Posted March 26, 2018 Share Posted March 26, 2018 while here I've pushed the lump down....no lump, no overflow...nothing else was changed. Quote Link to comment Share on other sites More sharing options...
Sophie Posted March 29, 2018 Author Share Posted March 29, 2018 Sorry for not replying earlier. I tried this out and you are right that this is what causes it. I also tried to keep the landscape the same, but then use a popcurve and turning of the wind. I tried to play around with the values and the ramps a little. It did give me some results closer to what I am looking for, but I ended up getting that lump out in the end anyway. When I use the suction and such on the river, I feel the result is a bit too strong. I tried to make a curve on the landscape and give it a negative suction, so it would be pushed away from the curve and the land. This did help a little bit, but it still doesn't work perfect. If anyone has any other ideas, I would still like to hear! The first give is the popcurve with wind, the second one is the popcurve without wind and with a suction force. 1 Quote Link to comment Share on other sites More sharing options...
