This would be my first topic. Happy to join the big TD family!
I am a very beginner and now I have a workflow where I want to created a fire(or plasma) op and hopefully convert it into a geometry and render it with another geometry which is an eyeball.
I was able to create the plasma using the Nvidia Flow op however it is a TOP, which I cannot convert it into a geomoetry. My current approach is connecting it to a trace SOP but that flattens it to 2D. I am sure there are other more appropriate ways to do that. Appreciate any and all suggestions!
you could setup the Nvidia Flow Emitter COMP to use either the eyeball extracted from the geometry you have, or a Sphere SOP placed at the same position as the eyes in your model.
The Nvidia Flow TOP takes as it’s first input a background which could be the Render TOP of your scene, and as a second input a Depth Map which can be retrieved via the Depth TOP from the Render TOP.
In the end this is a compositing process.
The depth compositing seems to be a bit coarse right now - I’m inquiring if there are ways to make this smoother.
Thank you so much Markus @snaut ! The information is very helpful. I will try it out later.
For now I had two layers of composition from 3 Render TOP inputs (eyeballs, model and NF emitter) with different draw priorities which works but the 3D/depth relation between the eyeballs and fire is sort of simple.
