3ds Max New Features Visualizing CFD as a gradient Once that’s done calculating, now we’ve got a gradient indicating the velocity on this plane. We can actually move the plane. Just be aware that the performance is going to be poor. If we want better detail, we’ll go into the plane primitive and increase the number of segments. Set this to 50 and 50. Now we have a pretty good visualization of the air flow within this space and that’s how to apply a gradient to an object in order to visualize computational fluid dynamics.
