I’ve had a very hard time with the Houdini tutorials lately, and so I was proud to even get through the first forty minutes following along. My smoke looks okay, but it’s doing something weird towards the end of the simulation, when a large box of light develops.
I was able to follow along until rendering, but then this happened. I’m going to book a session with Mehdi on Monday and just ask him what’s going on, I suspect there are multiple issues with my file.
UPDATE
I spoke to Mehdi and he informed me that the only issues were either with my graphics card or not hiding the geometry. I rendered again with the geometry hidden and was able to produce this:
The density adjustment slider was really interesting to me, and it’s cool to be able to choose between pure flames and a more smokey fire.
When it came time to render our simulation, I was at first met with the same issue as before:
But happily, I was able to solve the problem on my own this time! I realized that it was because the material shader name had not been updated and I reassigned it as well as making sure all the geo was hidden. As soon as I did, I got this image:
I feel that this week helped me understand rendering better and continued to help me get accustomed to the Houdini workflow. Being able to find my own material shader issue is a big step in the right direction of understanding the way Houdini nodes interact.
