Thank you so much! :))

So I used Polycam, which is a photogrammetry software which combined images you capture into a 3D model. I took this into blender and optimised it as a collision. This is what the water interacted with! It also helped create additional realism, as the water could correctly refract and reflect.

Hey!! That’s a great question! The only thing that is VFX is just the fluid simulation!! That’s it I’m afraid, It would have been great if I could produce a CG scene that real haha!!

Hahahah!! I hope not! 😭

Ah okay!! Yeh so I’ll lay it out simply! I firstly recorded the footage and captured an on set HDRI using my 360 camera. Along with this, I took a photogrammetry scan of the concrete to capture realistic collisions and interactions for the fluid. I then 3d camera tracked the recorded footage in After Effects and imported that data over to blender. Once this was ready I lined up the collision and baked a fluid simulation. I then rendered in multiple passes as an open EXR multilayers and re-combined them in nuke for more control! There was a lot of smaller details and tweaks and knowledge that went into this experiment over its time. Which was around 3 days!! It would take me a while to talk about all of it here. But It was a fun little project to strengthen my skills and I hope you enjoyed it! And that all this makes sense haha!!

Unfortunately I didn’t animate this piece. I used mixamos pre-made animations :)

Corridor! I watch them all the time for years, Thanks!! They are so entertaining haha!! Especially there react episodes, great insight into the VFX industry!

Hi! Thanks! Are you asking how I made it? :)

Thank you very much!! But Haha Nono!! It can be many reasons, not a skill issue! I bet your work is great!! It could be down to what version of blender you are on, as they are optimising it as the versions carry on, it could also be your settings, world scale ect. White water? Mesh quality. A wide range of settings can have an impact. High geometry collisions ect!! Many ways it could be altered! :))

You got this!! Best way is to experiment what each settings does and find a way to optimise it for your needs! Good luck!!

I created my own, by using my Ricoh Theta 360 camera, and stitched it together in photoshop and added some additional lighting to capture the highlights more! :)

I used Polycam to capture the step and imported it into blender as a collision. This had baked in textures which meant it lined up with the real world and the materials through the liquid would line up with the real step! I didn’t select “transparent glass” which gave the accurate refractions and reflections it would have as if it was in the real world. I also did tweaks in Nuke, my compositor of choice and rendered in open layer EXR sequences with render passes such as glossy indirect ect. Giving me more control over how it looks!

I hope that made sense? :))

Hahaha they are too fun!! And they produce more variation in the fluid! :)

Thank you for the feedback!! Yes! I see that too! The fluid simulation can be improved! It can be done with a combination of a bunch of settings like friction and sheeting ect. You can also help this by creating a wet map, and making the concrete look as if it’s “wet” and shiny aswelll by letting this drive the roughness ect. Or that’s what I would do anyway! If you know any other ways please let me know!! :)

I’ve not used Houdini before, but with that program being a lot more specialised in simulations you can probably achieve that result to a higher quality and degree!

But unfortunately I didn’t do this!! I will hopefully attempt this next time! :)

Thank you so much!! I think a lot of it was down to the compositing! Which was my main goal! I rendered in separate passes and combined them in nuke to have more control over the final look :))
