Flamethrower Sim
 I am using a Tutorial on youtube by Sadjad Rabiee as a starting point for this project, I am new to pyro so this helped me set up a very good base understanding of the workings of pyro.

Week 1
I Started off adding a sphere and added an x velocity of 20 into a point wrangle, then added some point velocity and curl noise before putting the source into a popnet.


This is the popnet simulation, in the popsource I experimented with the values of the inherit velocity in the attributes tab of the popsource and the life varianc and like eexpectancy rates in the birth tab in order to get a desirable look





I then used a volume rasterize to give the particles a volume to feed into the pyro solver






Feeding the volume into a pyrosolver


Baking the volume and customizing and shading the fire with pyrobakevolume node

In my opinion the smoke is too orange and doesnt dissipate fast enough into a more black and dark color which I need to tweak some more in the shader.

Added Particle Collision using popcollision detect inside of main popnet, then seperated the two souces from the popnet and fed the object collision particles into a new pyrosolver


Pyro Playblast flipbook, the object fire spread looks a bit too strong at the moment

Did a quick render test with an Hdri and new pyro bake shader within Karma. the lighting looks a bit flat so I tried out a new hdri.





5-26-2025 Update

Found a nice hdri and added a directional light
I also updated the shader and turned down the dissipation value to 0.04 to give it a bit more volume and tried to show a bit more smoke coming from the flame in the shader.

made some trees with the houdini tree maker. I ended up baking the branches in order to optimize the trees better because it kept crashing my machine
when I imported the trees into my lop net.


Used the Labs Maps Baker to bake the leaves onto a texture to place back onto the trees

Final Environment, tried to match the colors of the leaves into the hdri
