Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Stopping Dynamic Effects "going through walls"

Hey guys.

I cut a poly sphere in half to create a bowl. I then created another small object and added the dynamic fire effect(default settings) to it. I places the fire into the bowl. Problem is, when I render it, the flame go through the wall of the bowl. I tried selecting the bowl and particles and setting "make collide" but it didn't fix it. Any suggestions?

Particle collisions work currently by calculating the CENTER of a particle to the collision object.

So, no matter what the physical size of the particle, there may be interpenitration with other collision geometry.

Here is a tut that explains a "sortof" workaround:

The problem I saw with setting the collision was that it went all "psycho(TM)" My system almost freezes when I run it, and the parts I DO see, it has the particles going all over the place like bomb going off in a fireworks factory.

...but I'll check out the link, cheers Izzyuser added image

Well, for your particles going all haywire, one reason could be that you left the resilience and friction factors of your geoconnector at the default values.

Check the docs regarding "make Collide" and in there it will talk about how these 2 attributes are CRITICAL in pulling off this type of thinguser added image
