I tried to render a video of water slowly being poured into a glass cup.
In some frames during the rendering process, a glass spike appeared out of no where, in the downwards direction that the water is pouring (into the glass cup). I do not know if this is a settings problem but it seems to pop out whenever I try to render and at different frames. Sometimes it disappear after one or two frames.
The problem is that I did not see it in the wire frame or solid mode when inspecting the timeline.
Is the spike coming from the centre of the glass? If so it might be a modelling issue. Looks like the kind of thing that happens when vertexes get pulled accidentally.
For now, I can only render and remove the specific frames. By the way, how to you change the frame rate of the fluid simulation to about 35 so that I can cut without any lag in the final product.
Weird, I re-modelled the whole thing from scratch and use a different shape for the cup and baked the fluid witha different velocity, but it still happens. My gpu is not supported (nvidia 9500 gt, cuda version too old) so I was using my cpu (amd phenom IIx4 810) to render, not sure if it has anything to do with that.
I assumed the frame rate of fluid is governed by the animation rate in render settings. I’m also assuming in my limited experience that ‘fluids’ are ‘skinned’ particle clouds.
